This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.
Here's the Tube Zone distortion from MI Audio. Original has 6 knobs with the Presence pot internally as a trimmer, but I know how you guys like to fiddle with knobs, and the layout was turning into a 1590BB size anyway, so I made it external. Schematic available on FSB.
Precense also reversed and the 220n/100k should not go to the emitter but the collector of Q2. I would suggest using a B25k as Presence as stated before and if you want to be very puristic put a 100k between legs 1 and 3 to get B20k.
Effects Layouts admin you are great guyz for all the schem layouts. So far i had 45 buiild to date the latest is friedman be od.!im so honored to be part of this lead burning world! Tnx guys! Jun fr Philippines.
Great! Thank you! If caps are rated high enough, can it be powered by 18v?
ReplyDeleteI see no reason why it couldn't be.
DeleteVou testar esse projeto com dobrador de tensão chaveado para poder usar o pedal em 9V ou 18V.
DeleteCuál es el reemplazo del lm833, gracias
DeleteI think you could best change out the B20k presence for a B25k since there are no (cheap) B20k external pots.
