Here's the deal. I love the clean sounds from my Maz 18. I think it's the best clean sound I've ever heard. BUT, I really am not liking the cranked overdrive sounds. The top end fizzes out really bad, and the notes are still really focused and "in your face" for lack of a better term (I know that sounds like a contradiction, but the focused note hits, and then the fizz kinda trails off). This is probably great for country or blues, but I need a rock amp. I have been using a TIM with good effect most of the time, but I've been thinking more and more about something with more natural grind to it. Current owners: Anyone have ideas on making more of a smooth overdrive by cranking the amp? Tubes??? Former owners: Has anyone switched from a Z and found another amp with comparable cleans and better overdrive? I'm looking into amps like the Bogner Metropolis and the Aiken amps.
