Re: Fender style/Brown sound/Dumble PCB boards

Are there any recorded examples? I'm curious how the noise floor might be on the crowed pcb's

Re: Catalinbread - Katzenkönig [traced]

Mesa was also known. [ or merely said to have, possibly by themselves ] to release schematics with intentional mistakes

Re: Sonomatic Doctordrive 2 [traced]

How do the Vic values compare to the ocd ? Since full of himself's designs are often variations of something else, what proceeded the ocd or was IT based on?
[ edit I see it apparently is similar to the voodoo labs o/d , now which egg came before that ? ]

Re: Sonomatic Doctordrive 2 [traced]

Nice job so far, though if it's just an ocd is it worth the bother ? It's tough to get out of the case, pcb soldered in place to jacks after they're installed ?
I can say there is the 4148 protection diode in the lower right hand corner between the jack & pwr jack

Re: Sonomatic Doctordrive 2 [traced]

This pedal never had that sticker, but I think I'll just buy it. It's reasonably satisfying to play, I thought ocd were higher gain ? dr drive feels like diodes in the fb loop but maybe it's just a reduced gain ?

Re: Sonomatic Doctordrive 2 [traced]

60mm x 90mm this is all I have for images of the copper side. The trace broke off of the led so I had bent the lead over that's why it looks ugly.

, it's a light/med overdrive so I wouldn't think it an ocd, I could be wrong i never liked [ or tried much ] ocds but I liked this box

Interesting how one guy kept the look and the other went way different [ with more offerings ]

Exactly , I can't find a website for these guys, though I see someone selling their version of an 808 on reverb, Similar case form factor, which is compact and sturdy, well designed I think. i fixed one for a friend that the dc protection diode blew when it was plugged in hot, it arched which was he...

Sonomatic - Doctordrive 2 [traced]

Anyone know this pedal Sonomatic Doctordrive 2 , made by a company in Buenos aires Argentina and billed as a 18watt amp emulation
It appears to have one opamp & two transistors but if it's a yats it sounds pretty good for a med/ lo gain pedal

I haven't built this yet, [ but will ] but here a blurb apparently from a reverb listing quoting PG Super rare and out of production! This pedal does what it promises... super transparent and powerful OD. So many OD options with one pedal. Great shape and fully functional. 3M Tape on bottom. From PG...

Looks great, straight forward thanks, you weren't tempted to put a second stage volume [ master ] at the end ?
