I honestly dont mind how it sounds clean, but if I run a fuzz through it, I find myself in need of ear plugs. Bright and shrill. I plugged another speaker (WGS G12C/S) in -- problem solved. Now that I think about it, I also had a Maz 18 that I sold because I hated how it sounded with my fuzz pedals; it also had a G12H. So what should I replace it with? I want something fairly effecient. The amp is a Bruno Cowtipper.
