SOB Limiter Mod?

[greg777]

Hi, First time on the Boogie Board, never had any problems with a Boogie before so never had to ask!

I have an old SOB "Son of Boogie" and it says presence on the faceplate put it is actually a limiter/attenuator. Let me just say that the limiter is terrible! I usually hate attenuators but I don't know how this useless feature ever made it onto a Boogie?

Any ideas how I could remove the limiter and wire in a standard presence knob? From what I understand of Fender amps is that a presence is usually wired to the negative feedback?

Any ideas would be helpful.

Thanks,
Greg
