Popular Mark III Modifications

[Boogie Bill]

I have two Mark IIIs. One is a 200-watt Classs AB Coliseum Head with reverb and EQ--no color stripe. I have a C90/EVM 412 Halfback cab that I like to use with this amp. My other Mark III is a blue stripe Simul-Class combo, cream with a gold grill, EQ, Reverb, and 112 EVM.

What are some of the more popular, practical modifications to make to a Mark III?

Thanks,
