Re: Boss - OD-3 Overdrive [schematic]

Is there a verboard layout for the OD-3 with true bypass?

I only found a simplified version.

Fernandes Sustainer installation manual / schematic EARLY version

Hi, I'm looking for an installation manual and/or schematics for an early version of the Fernandes Sustainer circuit. I bought a guitar from the early 90s, the Sustainer works, but the wiring is a complete mess and the lever switch is broken. The circuit has only two trimpots and no coil on the pcb....

Re: Whisper of Screams (Kasha OD Pedal Trace) [traced]

Nice! Do you have sound samples?

Have you tried to replace the 1m resistor in front of the second transistor with a pot? Maybe this could replace the "whisper" mode?

Why do they use such high resistor values at the output?

Re: EMG DG20 (SPC and EXG) schematics etc.

I'm still not sure, which opamp is best for the SPC midboost with input buffer. - OPA2134 and LM833 produce distortion/oscillation. There is some positive feedback in the circuit, which might cause this. - 1458/4558. Better, but current draw is a bit high for use inside the guitar. - LF442. Best sou...

Re: weirdbrato 2399

This could sound funny in the feedback path of a delay.

Re: Hotone - Soulpress

Nice sounding wah with one mistake: It's made for small pedal boards, but you can't place it close to a power supply because it hums like hell - the inductor isn't shielded. I could add more pictures if someone really wants to draw a schematic. I don't think that it makes sense to build a clone, as ...

Re: Can anyone check my Boss OD-1 Schematic?

I tried values from 220k to 1M and ended with 470k. A lower value might work better if you want a lead tone, but I use the pedal to add only a little bit of dirt, and I use totally clean amp sounds without any effects a lot of the time. In that case, the 220k always sounded a bit "muffled", compared...

Re: Can anyone check my Boss OD-1 Schematic?

Increasing C1,C7,C8 or C9 doesn't make any sense. Calculate the highpass filters... There's no audible "mod" in the last schematic, only the bypass signal switching is removed. The 1M pulldown at the input lowers the input impedance, which is extremely low anyway. Maybe increase the value of the 220k?

Re: Can anyone check my Boss OD-1 Schematic?

Can't R4 and everything below it simply be omitted? They were part of the clean signal path for the buffered bypass.
It's R3 in the first schematic with parts values...

Is there really no better solution than using transformers as inductors?
4700uH inductors are avaliable on ebay.
