Soft BB preamp

[panchokunstmann]

Long time without update.

is a BB Preamp slightly modified:

in the diode # 1: The modification is an old diffuse green led  versus 1N4148 diode. the green led sounds less compressed, more organic and less saturated but the 1N4148 diode also has its charms.

Well, I used a JRC4580D that also delivers a less compressed and more organic sound that JRC4558.

Also I changed the curve of potencimeters (Vol and Gain) for a logarithmic curve, I think it works much better than linear curve.

inside: ( as always, I'm not proud but I think I'm improving )

I really like the way that you tweaked it to how you wanted it to sound.

Clean & simple. I like it!
1N914 and ilk are my least favorite way to clip a signal. I bet the LED sounds great in there.

Simple but elegant an killer sounding I would imagine. Great build.

Oooo, very tempted to try the LED clipping in mine. Might socket and try a few different colours etc. Was it a 3mm diffuse you used?

Thanks to all, really is very pleasant forum   .


It is a 5mm led, I'll try different colors this weekend and some diodes that I have.

I'll tell you how everything is going

The pedal really sounds great, I love it
