I know some if not most will say this is a sin but there is a tone I'm after that I believe the modding process can help with. I want to put in a high quality tube fx loop plus I want the treble to be less spikey. I believe that's the technical term. I checked out Voodoo Amps and FJA mods. Any others out there that I should look into to? Also, I'm near Chicago so a local tech that specializes in Marshall would be a great point in the right direction.
