Music Man 65 Amp-in-box Overdrive

[lioonel_dg]

Hi there,

I love the overdrive flavour I get from pushing the front end of my Music Man 210-65 amp with a clean boost. I wanted, for versatility purposes, to recreate that sound in a pedal format. I thought I could just cascade in the same pedal, a boost circuit into a recreation of the preamp stage of the amp.

Could you help me determine up to where in the schematics, would I need to copy the preamp circuit in order to be the most effective ?

Thanks a lot for any help !

The missing piece of info is can you get the tone you want with the Volume control turned down and Master up.  If that was the case you only need to mimic upto the Volume control.   Otherwise you would need to mimic upto the Master volume.

I can get the tone I want with Volume down and Master up. So mimic up to Volume control I guess ! Thanks !

I did a pedal/preamp PCB for the HD130 preamp section.  It has an onboard +/-15V supply too.  Design files are up on oshpark and github if you want to get some made.

Do you get the desired tone in either channel or only in one of them?
