Hi y'all.  I'm new here, name is Mark Lee Hunter.  I play mainly solo dance music, from Handy to Prince, usually open tunings with slide.  Live in France, play out often. Gear: Reverend USA and import guitars (I'm a senior contributor on the Reverend forum), also USA Washburn and Curlee, Supro Resophonic, Charvel bass, Hohner OSC.  I like buying cheap gear and fixing it up and have modded most of my guitars. Have NOT modded my amps, which include  Bassman 100 export head (big and HEAVY), a pair of Crate Powerblocks ( <3), Microcube, Pignose classic, and Champion 110.

I got the Champion 110 cheap a decade ago, thought it was OK in the store, have never liked it since.  Changed the speaker (for a mid-heavy Fenton, French, not bad), still don't like.  The treble on this thing just cuts my ears, hate it.  If I could cure that I could live fine with this amp.  So what I want to now is: Is there a fix for this sort of thing that involves, say, changing a capacitator?  If so, any good things to read before I change it (so as, say, not to get electrocuted)?  Or is this gonna be a killer job that drives me nuts? 

BTW, glad to see there's a forum like this.  I LOVE solid state and digital gear, because it's light, usually inexpensive, and can be made to sound great, and doesn't break or blow up all the time.  Why I bought 2 Powerblocks... Thanks in advance for any counsel.
