KAISH 10pcs Clear Guitar Scalloped Edge Amplifier Knob Transparent Cylinder Effect Pedal Knobs

I was happily surprised they fit my Korg Triton X treme 88. These knobs are fully round and my Korg has the flat on one side type, plus a couple of mm smaller in diameter.The replacement knobs showed up on time and I didn't even have to Shim the shafts. Screwed the set screw onto the inner flat side and it worked.As far as longevity I cannot say but the feel and sturdy and easily allow me to turn my effects with no wobble

Some boss pedals have closely spaced control knobs and need a small diameter control knob at the base. Also the Boss original knobs are not tapered as many knobs on the market are. OEM stuff from Japan was ridiculously priced. Although these are not push-on knobs as most Boss original knobs are, they went on perfectly and were easily secured with the set screw. There is no wobble when turning the knobs as they fit the pot shaft diameter very well. Be aware that these shafts measured 6mm, the control knobs space is slighter more than that at about 6.2mm and also that 1/4 inch does not equal 6mm precisely, as much of my online research seemed to point to interchangeability. Hope this helps someone out there!

The strength and weakness in this product is one in the same. They have no metal tube in the center, so they are lightweight and get little cracks around the set screw holes, but they are also very clear for light effects. These will work on those illuminated kind of pegs you see on the Volca or Monotron series. These are standard guitar pedal sized knobs, so they are probably too small for your actual guitar. Luckily, the small cracks don’t seem to cause them to break, so I will be buying more of these eventually.

I had bought the RG-1 years ago and never really considered the knobs to be a problem, but as I got older, I found it harder to see the designation "line" on each knob on-stage or under lower light conditions. So, I noticed some folks were changing the knobs out (saw online) and I thought I'd give it a try. These particular replacement knobs have set screws. The RG-1's pots have the flat-sided posts and the original knobs have inserts to accommodate those posts, so, the set-screws are pretty much a "must". They fit "ok", but not perfectly, however, the reasonable price and quantity make this a great alternative to dealing with the original shiny, hard-to-see knobs. I'm certainly considering these replacement knobs for some of my other pedals, too. Very cool way to customize your pedals!

Durable, screws tight. Using these on my Roland SP-404sx as replacement knobs.

Bought 3 sets of knobs, 1 black and 2 transparent. The Black set was fine but the clear set were the worst quality aftermarket knobs I have ever bought. Overall the exhibited poor workmanship. Finishing on the plastic wasn't very good: sharp edges, plastic burrs inside (I had a lot of plastic bits fall out of them) and holes for brass screws not fully tapped on most of the knobs. Additionally, I had one knob that the screw just popped out. Would not buy these again.

Great knobs for some pedal projects. Purchased this DeltaLab with only one knob, and I picked up the orange for a nice contrast. Then my friend built me a God City GCI Brutalist Jr Bass pedal. I had extra knobs left over and they worked perfectly. Nice knobs with a good look.

I recently bought a used Digitech RP350 guitar effects pedal, and some of the knobs were missing. Looked at lots of potential replacements but none fit. Ordered these and thanks to the set screw design they are a great fit (except for one knob, which is a special case anyway). So now my RP350 has a full complement of knobs, looking cool and sounding great.
