Hi

I did a search and found ssme good info, but I wanted to be sure I got this right before I gave it to my tech to try or did it myself. I will not try anything I am not comfortable with, I have plenty of help, I just need info and schematics.

I have a Bogen L330 which sounds nice, but needs a few things for me. I need a master volume so I can overdrive more quietly. I did find a few schematics and useful threads on here as I said, but I'm not sure where the ideal place to put it in is, or how.

I am also going to put in a fender tone stack if I can. I found this thread

but I think our amps are slightly different. Mine has a voice filter switch for one. Any advice or schematics that could help me?

Thanks!
