Donner Reverb Guitar Pedal, Verb Square Digital Reverb 7 Modes Room, Hall, Church, Spring, Plate, Studio, Mod, True Bypass

For the cost I cannot find anything to complain about with this pedal. The Donner Distortion pedal allows me to produce a wide range of distortions, from a relatively mild, overdrive tone, to hair metal. Adjusting the tone and volume using the knobs is simple, and the noise level is not overwhelming, and disappears completely when using a noise gate. I've been practicing and gigging with this pedal and it has held up great so far. It is powered by a standard, 12v power supply (not included) If you're looking for a compact, inexpensive, distortion pedal for your board, I highly recommend this one, it does a nice job at a great price.

So I ended up with 2 Harmonic Square Pedals. Wanting to gift one to a friend, I plugged them both in at the same time, you know... keep the 'good one' hehe. WOW!!!!!! I cannot describe how nice they sound together -running one into another. Used separately they work very well and do what they should (including a killer chorus in the 'detune' setting) but together they sound so rich, deep, full, shimmery and expensive. With both of these on at the same time there is near endless settings just flipping the switch and turning the pitch knob. Easily sounds like a $450 effect. Run these into a tad of reverb/delay and it's absolutely amazing ambient heaven. It could be one of the coolest pedal combo's for shimmer/pitch/chorus/octaving/doubling... SO GLAD I ACCIDENTLY TRIED THIS. So in short, I'm buying my buddy a new one.

I really enjoyed using the looper pedal by Donner. Once again this brand delivers an excellent product at an extremely low price point! The controls are very easy to use, though I did notice a slight difference in sound quality when being played back through my amp, not too bad though. I removed a star because I noticed another persons pre recordings were saved to the device but that’s hardly a complaint. I would definitely buy again!

Surpassed my expectations. I was picking this up just so I could use it for down tuning, turns out the dry/wet knobs give uou some amazing results when it comes to crazy effects. Well worth the low price!

This is a good guitar tuner that is solidly built with a solid foot switch. A lot of these budget pedals have very cheap foot switches. Hopefully this tuner holds up better than the Mooer tuner pedal I bought. I crapped out in six months. These are great pedals for the bedroom pro like me.

This is the first Amazon review I am writing, and I am only doing so because the quality control of the product is so bad as was the customer service. I am a fan of Donner. I have other products by them, including pedals of this same line. But this 30 minute looper just doesn’t cut it, and considering I have bought 6 (yes… actually 6) of them it’s unacceptable. And before anyone suggests that it’s because of my power supply: I have two different Donner power supply units, each working perfectly fine with the rest of my pedals and effect boards — I also have independent power units, and none of them fix the issue. The issue is this: For one, a general white-noise ambient hiss is present. This I honestly don’t have much of a problem with. The main thing is that when it’s recording every five or so seconds a strange and harsh digital chirping/beeping sound occurs. This sound is recorded into the loop itself. Naturally, as you make various dubs, the chirping noise is compounded and compounded and the whole arrangement is quite annoyingly taken up with this recurring beeping. I originally bought 3 back in December. My mailman stuffed those one into the mailbox on a particularly rainy week and decided not to close the mailbox for whatever reason. Given, it was wrapped in plastic and all. Anyways, these pedals didn’t work. I attributed this to water condensation or something. I returned them no problem and I bought three more. Same problem. At first it was 2/3 of the second batch that didn’t work, but then they all started doing the same thing. This isn’t a problem with a particular amp. This same thing happens on my guitar amp as it does on my bass cabinet as it does through my mixer and out my PA’s. It’s not a problem of my cables. I have dozens of different quarter inches, some I got even brand new alongside this purchase, and same issue. I reached out to their support team and explained the issue and the lengths I went through to troubleshoot it myself. They asked for video proof — which is fine, though they said it needed to be less than 20mb. This is what they said exactly: “Dear Customer, Thank you for responding to our email. We hope this email finds you well. We are humbly asking for your cooperation to send us videos so that our technical team can localize what the problem. Rest assure once our team know what the main problem is we will provide suitable solution to solve your problem. Please operate it and send us a video showing the operation and explaining the problem. (Note: The video should be less than 20MB in size.). Once we receive the needed information, we'll handle this matter with the utmost care and attention to detail. Looking forward to your reply.“ I said, “I filmed a video showcasing and explaining the issues, but I have no idea how it’s going to be able to only be 20mb in size.” (My 3 minute video to them shot on my iPhone amounted to 328mb) I then went on to say I can send them a google drive link, which I did. Their next email was them mechanically repeating their former email to me, saying once more after I already sent them the google drive link. This is it: “Dear customer, Thank you for reaching out to us regarding the issue you are experiencing. We sincerely apologize for the inconvenience you have experienced with our product. Could you show us the problem via video? Could you upload the video (less than 15 MB) as an attachment. Rest assure we will do our best to solve your problem” This could just be a minor mishap, bur they switched from it needing to be under 20mb to them needing it to be under 15mb — which leads me to believe it’s really not some hardline technical consideration as to why they need the video to be such a size, and they could very well just click on my public google drive link to the video as they clearly have internet access. All around upset with this product and their service. Going to go through with my second return on this same product and shop around for different loopers — I was just very excited at the prospect of having 30 minutes of loop material, as I compose very experimental and trance-like songs, and so this was in theory absolutely perfect for my purposes, especially considering the price point.

I am hijacking my wife's account to post this. Hopefully it helps. Over the past couple years, I have purchased every Nano and Mini Pedal that Donner has made. Some of them I have two of. Some I do not use at all. Only because I prefer specific ones over the others. For instance, I have the Verb Square, Echo Square, and Mod Square pedals, but prefer the Yellow Fall pedal for its simple operation. I also have all the Super Mini or Nano pedals, which are also great, but decided on the Mini Pedals for my set up, just because of how they can be configured so closely using Getaria cables. After many reconfigurations and finally watching a 1 hour YouTube video interview with Steve Vai about the principles of splitting a signal and playing in stereo, I set up a couple amps, and now have the option of playing in stereo using several Donner pedals that I feel produce the best signal path that I can control to create the voicings I am looking to emulate. For starters, I have a 1973 Peavey Studio Pro 40 that I use as my amp head that has been in the family my whole life, though I have only seriously learning to play guitar in the past few years. It was barely used until it was passed on to me, and probably not utilized the way I am using it now. I also have an Acoustic A20, an Acoustic G120 DSP, and configured an old set of Infinity speakers (two 1x12's) into a cabinet for testing the quality of the unbalanced line out on the Peavey. After two years of playing around with the pedal configurations and watching the Steve Vai interview, I have settled on this configuration as the optimum path for pushing the cleanest signal until I am ready to manipulate it: I run the clean signal from the GTR into the following Donner pedals listed in order powered by two DP-1 power supplies, and one DP-2 power supply, with the majority of the pedals mounted on a DB-3 Pedalboard for the main signal path: Donner Wah Cry (wah/volume), DT Deluxe Chromatic Tuner (tuner)*, Ultimate Comp (compression/sustain)**, Stylish Fuzz (fuzz/distortion), Extreme Driver (boost/overdrive/distortion), Pearl Tremor (phaser), Blues Drive (gain/overdrive), Boost Killer (gain), Morpher (distortion), Giant Metal (boost/distortion)***, and Viper (passive volume) pedals into Channel 1 (high gain) on the front of the amp. On the back of the Peavey Studio Pro 40 amp are jacks for an FX loop, an Unbalanced Line Out (ULO), and a footswitch controller. From the back, it comes out of the Send jack into the following Donner pedals: Noise Killer (noise gate/ suppressor)**, Jet Convolution (flanger), Harmonic Square (octave/pitch shifter), Tutti Love Chorus (chorus), ABY BOX (line switch) [pay attention here], Yellow Fall (delay), Golden Tremolo (tremolo), and finally into a Looper (loop station) which then goes into the Pwr In (Return) on the back of the amp to complete the effects loop. On the back of the Peavey, since it ALSO has the ULO jack, the signal coming out of the ULO can go to a mixer, recorder, another combo amp, or speaker cabinet. Using the ABY switch to split the signal before the Yellow Fall (delay effects), I can send a signal path to another amplifier and play in stereo (in this case, simultaneously using the Studio Pro 40 and the G120 with the slider switch set to ABY). If I use the ULO and utilize another speaker cabinet set-up, it enables me to use the Peavey as a monitor with a simultaneous split for a 3-channel Surround Sound Stereo effect. Using the ABY switch immediately after the Tutti Love Chorus, the signal path 'B' gets sent into Channel 1 of the Acoustic G120 DSP (high gain) on the front of the amplifier. The signal comes out the FX Loop on the backside (Send) into a MOOER GE-100 (configured to preset #64 'PreAmp Driver', or #65 'JC Amp'), and then into a second Donner Yellow Fall (which is the same delay pedal as on the 'A' signal side of the ABY BOX) with the echo, time and feedback settings compensated so the Acoustic G120 sound washes over the output of the Peavey Studio Pro 40 so that the delays in sync. For a regular set up (Dual Channel stereo), the Peavey is directly in front of me, with all the foot controls comfortably within reach, and most of them on the Donner pedal board. Any other amps or cabinets are about 10 - 15' away to the left and right facing out. This set up CAN BE VERY LOUD! The Viper (passive Volume/Expression) pedal is key to controlling the signal level and achieving the sound you want, based on your guitar, how hot the pickups are, the strings you use, etc. But it can also be soft, clean, warm, bright, rich, or spacey. With just one ABY switch at the end of the signal path, just before any time effects are applied, the signal is split into A and B, enabling me to play, A, B, or Both (Y). Playing 'Y' (A and B together), I can play in stereo (up to 160 watts), and with the 'B' signal passing through the MOOER GE-100, I can wither use its metronome feature, or select from a variety of preset drumbeat styles and adjust the tempo to play along with. It also has an MP3 input, to play along with your favorite songs or prerecorded tracks. It also has its own looper with over dub features, so between the MOOER GE-100 and the Donner Looper, I have 2 loopers available to play multiple riffs of up to 10 minutes at the same time. And if I really want to get crazy, the MOOER has 80 preselected voicings to use with its own integrated volume/wah pedal (as well as room for 80 more user programmed presets). This enables me to split the signal and have one guitar playing like there are two; either playing the same notes with two separate effects signals, or playing in unison with the same effects signal. Yesterday I added another ABY BOX Line Selector between the GTR and the Wah Cry to go into an Acoustic A20 amp (for acoustic and hollow body guitars) to use as a lower watt amplifier head and/or monitor plugged into Channel 2 on the Acoustic G120 DSP. Using the ABY Boxes and a Line 6 (2 button latching footswitch) to switch Channels on the G120, I can direct the signal to go from the Peavey into the G120 DSP (toggling between channels 1 & 2) or into the A20 and come out the FX loop and through the MOOER and any other effects (I can take the MOOER out and toss in an entirely separate set of Donner effects or cabinet simulator effects pedals -- Dynamic Wah, Sweet Juice, Incredible V, Green Land, Force 2, Black Devil, or MOOER M005 Brown Sound as well or in the ULO path for different cabinet simulations). [A side note here: I am exploring the possibility of adding a EarthQuaker Devices Swiss Things Pedal Board Reconciler for more control in place of the first ABY Box (between GTR and the Wah Cry) and letting it manage one of the signal paths to either the G120 DSP or a more aggressive cabinet setup like a 200w Marshall stack (400W total).] All the effects pedals (stomp boxes) are true bypass, so depending on whether I want to play some blues, pop, funk, rockabilly, country, rock, metal, or jazz -- it just depends on which guitar I pick up (acoustic, electric, hollow body, semi-hollow body), what effects I apply, and where I direct the signal. I have my sights set on a Marshall cabinet (or stack of two) to have a 200w (possibly 400w) option available and still use the Peavey as the amp head because it has the one thing the Acoustic G120DSP doesn't -- an Unbalanced Line Out to be able to play in stereo or with a smaller amp and integral FX loop as a monitor. With a double latching Peavey footswitch connected to the Studio Pro 40 (I cannot find a vintage Automix, so I have a Peavey multi-purpose 2 function footswitch), and a double latching Line 6 footswitch connected to the G120 to change between high gain or low gain input channels, though they create a pretty large footprint with all the pedals and footswitches, I have total control as I play. It is important to note that the placement of the PolyTune 3 serves as a kill/mute switch for everything but the drumbeat or metronome (there is a Rhythm switch on the MOOER GE-100 to turn this feature on and off). This set up can be pretty interesting, and is definitely a lot of fun! Though I have them all, I have spent significantly less on the Donner brand than any Boss, MXR, or other major brand to have all the effects available to recreate any voicing -- from a clean 50's vintage tube amp, to a heavily distorted or modulated brown sound -- I can dial it in through the Donner configuration, or choose a preset in the MOOER GE-100 and play along or improvise my own music. *Note 1: I will be replacing the Donner Chromatic Tuner with a PolyTune 3 for more immediate recognition of which string may be out of tune and higher tolerance. **Note 2: Depending on your amplifier's ability to apply more equalization to the signal pre amp and/or post amp, you may want to consider a 5-band Graphic EQ (filter) either between the Ultimate Comp and the Stylish Fuzz, or immediately after the Noise Killer. ***Note 3: Fuzz, gain, overdrive, boost, distortion are in increasing order of how many ohms they utilize and the dB they output in order to eliminate accumulation of line hiss that is common when high gain/distortion pedals are in series despite whether they are true bypass.

Pros: good sound quality and versatile effect options. Cons: noticeable volume reduction even with the level knob cranked all the way over. Also, I found that the rotary fx controller is way too easy to move and I would end up inadvertently changing the effect when I was hitting it on and off in a hurry. I ended up returning this pedal and went with the Valeton Coral Mod II which has better detents for each fx mode on the rotary switch.
