I was thinking of buying one. Is it ok to use it with overdrive and fuzz pedals? Or are the inbuilt amp functions good enough(then i can sell my OD..a boss bd-2 and not buy a fuzz) Since i can't really afford a tube amp, i was wondering whether it will be able to simulate an amp. Will it be better or similar if i go direct into the P.A. with the tri ac last in the chain(gain at 0, getting all Drive requirements from my pedals) than going direct with just the pedals. And does it respond to picking dynamics?
