Does anyone own this amp? I'm thinking about buying it after comparing it's sound with the Ampeg BA 115 (great, but much more expensive) and the Gallien Krueger MB 115 (it wasn't what I expected...). I haven't found ANY useful review of the W, though. Currently, it's the best I've tried (talking about sound/price), but I'd like to hear some owner/user's opinions. I used the aforementioned amps with a Schecter Omen Extreme 5 bass. PD: I'll try the Fender Rumble 150 before taking any decision. Thanks for your help!
