If any of you get a chance to check out philjonesbass.com ,do it. I just bought (2) 6 pack amps and i'm very pleased to see something difrent on the horizon. I feel the low end and the mid range of my instrument finally sounds true. It also sounds great on my banjo and dobro!!I have a huge rig ,but these amps give me another perspective when it comes to finding my tone! I'm freaked out. I plug my Madison Hydras cabs into them and they drive the hell out of them.!!
