Title: Marshall BB2 mod - hard/soft clipping mod
Post by: George on May 04, 2016, 01:40:07 PM
Today i modified my BB2 to  true bypass and i was thinking if i could easily do the soft/hard cliping mod that is mentioned in the 8BALL document.

With a DPDT (on-on) switch you can switch the diodes out of the feedback loop of the op-amp and put a pair of red LED's to ground as clippers.

I am not savvy enough to draw you up a diagram on this, but that's the idea.
