Hey Folks, I've got a Mesa Boogie Bass 400+ and would like to get another amp that will compliment the 400+ in terms of different tones available. As a starting point I've tried a Thunderfunk 750A and liked it. Love the idea of an Ampeg SVT-4 Pro, Aguilar DB750, and Gallien Krueger 2001, but never heard any of them. I think the hybrid route is calling me but would like your thoughts please! BTW I run the amp thru Mesa Diesel cabs (4x10" & 1x15") with a all kinds of basses (P's, a J, Stingray, Gibson LP) 'Cheers' Jon.
