Ampeg J-20 Guitar Amp Mods

The Ampeg J-20 Guitar Amp was recently blown out for $299 each, so I picked one up. The amp seems to be fine enough to me, based on what little playing I've done through it so far. Amp modifications (mods) are part of the tradition for amp enthusiasts, so in case anyone got a J-20 and is looking for ideas for mods, check out this thread on The Gear Page.
