Im lookin for a mid size gig amp. I don't like tube, they're expensive and something about their cleans dont work for me. I like SS. But how you can take lets say a Fender Champion 40, and stop the break out at high volumes? with a higher wattage speaker? lets say 75 or something? I've reduced my choices between Fender Champion 40 and Mustang II V2 (40 wts). Since I travel a lot, I need a small but powerfull amp, that won' break the bank, and will take the punishment of transport.
