I had concentric pots on my weirdo 70s Tele bass. It had the original WRHB and then someone added a Jazz pickup near the bridge. The wiring was fucked, so I set it up to have two pots. 1 pot per pickup, the bottom was volume and the top was tone. Honestly, it worked out really well for that specific purpose and was a great way to get the max amount of versatility out of that bass!

I have never met a concentric pot on an instrument that I like. I have a concentric bass/treble on the active fender jazz bass that I used in Replicator. It seems okay, but it's still annoying. I keep waiting for the active preamp to die so I can put in two loud, passive J bass pickups wired to one volume knob and call it a day.

I've never had them on an instrument, but on pedals they are fiddly as fuck. OK, I don't have the nimblest of fingers but fuck a concentric knob. I inevitably end up constantly resetting them, as I've either nudged the other one by accident, or I have turned the wrong one (or have forgotten which is which). Fucking hate them. (WF:7 sausage fingers)

Hate concentric knobs. Yuk.

Perfect! I'd been lusting after their chorus/flanger last year, can't believe I didn't think they might make a tremolo! Thanks!

Pedal Builders!

The pedalpcb Chop Shop clone of the V1 Fairfield Barbershop - Is it spec'd out to take 18v the same as the real deal?




...or did it fry mine by doing so [/eyeroll]?

The only thing that would probably be prone to getting fried would be under-spec’d caps?

Agreed, and specifically C100, the 100µF power supply filter cap which the PedalPCB build doc specifies as a 5mm diameter. Looking at 100uF caps on Mouser the voltage rating for anything 5mm or smaller maxes out at 16V.

Ooooh that's unfortunate about the 16v thing...

Found a guy one neighbourhood over. I'll pass that on. Not a spendy fix I hope. Thanks!

It ought to be very easy, and you could probably have the guy put in a higher voltage spec one so long as it fits.
