Marshall Guv'nor (original) mods

[thugler]

So, I really like the sound of the distortion on this pedal (I think i have the korean version).

I was wondering if there are any modders, preferably in the uk who would be able to increase the bass output and make it a bit more usable? I've heard that there are some mods out there but I wouldn't know where to start.

I'd be grateful for any info from those who've tried modding the guv'nor themselves too
