Re: Nux looper core pedal malfunctioning

I think other owners of this Nux pedal have reported issues.

Maybe use an audio probe ?

Re: LCA Guitars overdrive/distortion

Despite the 'rat's nest' build, debugging might be simple. Perhaps a shorted wire? Clean up the circuit traces? Looks a bit 'hairy'... (could also be a complete diy nightmare too...!) ******** Funny, a local audio tech used to do what I considered 'bullshit' repairs. Quick fixes and then wrap with e...

'SRV in a box' is a questionable claim to fame....and I wasn't disappointed, a couple of IC's.

Finished my clone this weekend. Love it so far. Very versatile booster or eq or both. Used a cheap eBay china 1590B enclosure (~4$) and cheap chinese knobs. The quality of both is surprisingly good. Love the raw sanded look of the enclosure. Overall design is heavily inspired by Mr Jon Lyons work a...

Re: TAD Range King schematic [traced]

R1 & R2 are both 100k? Is that verified? Thx. I ran a simulation of this circuit and found the collector voltages as follows: Using R2 = 100kOhms : 1.8 Volts DC Using R2 = 10kOhms: 7.7 Volts DC A collector voltage of about 7 Volts is common in the known Rangemaster circuits. IMO the Value of R2...

Re: BJFE-Baby Blue [traced]

Thanks for your hard work!

Do you have any idea which JFETs the original circuit used? Any voltage readings on the original JFETs?

How about D3 & D4 ? What kind of diodes?

Re: VFE Pedals official schematics - 11 so far

Many thanks for your thoughtful insights Peter. I for one appreciate your candor and 'open source' approach. I find the pedal 'business' quite fascinating. So many sellers competing with each other, mostly selling small variations on similar circuits. Sadly, success is more often due to clever marke...
