C24 -> Tantal capacitor Volume and HiCut Pot. -> A curve It's must for everyone.

Is it similar?

Catalibread drive pedal is not easy to make. I made it with the same parts as the original as much as possible. The result is awesome.

No doc on website. Can I use L78L15, Silonex 7532 and 7371 lamp for this Vibe?

Sanguine, Malachite both pedal used 4.7nF but Tyrian used 2.2nF for C6. Has anyone ever replaced C6 with 4.7nF?

Does it look similar? Choose high hfe(280-290) 2n3904 TR. Low hfe(190-211) TR makes poor sound.

My favorite setting is diode clipping off. BTW Presence knob works reverse. (Zero position is Max.)

This is my version of Centaur. I did best I can.

Use tantal capacitor for C24. This is must. Most important thing for making this pedal.

Nichicon FG capacitors were using for both 2.2uF, 22uF. Opamp is LM833N chip. I tried so many opamp chips but this is the only chip which didn't make noise. Strongly recommend.

Satisfaction guaranteed.

1/2W & 1/4W resistors EPCOS MKT, Pilkor & Orangedrop Cap Nichicon FG 6 of MPF4393's.

Nice optical compressor !

It was builted in October 2018 but has been upgraded so many times,, and finally completed today morning. I'll never open it again.

My version: R2, R3, R4, R6 ; 1/2W carbon composition resistor. It makes sound rough & muddy. R5, R7 ; carbon film resistor The other resistors are metal film resistor. Trim 1: 4.0V Trim 2: 5.0V Trim 3: 8.0V

- Carbon film resistors for all signal path. 6 carbon composition resistors for R2, R3, R10, R15, R20, R21. - R3 is 1k, R10 is 680. It's original pedal's correct value. I did R4, R11, C18 Mod, but now back to the original values. These mod make pedal easy to use, but lost magic that only exists...

Hot and smoking~!

Maybe the best preamp pedal?

Sustain Potentiometer - C50K. It's correct curve for Sustain.
