I use a Conklin GT7, a Yamaha RBX350 that i defret. Both thru a A/B box into a Bass V-Amp from Behringer, and it goes into a custom made 200w Tube Amp, with 2 cabinets of 15". It sounds great, and the low frequencies are incredible. I also have used (and sold) a Ibanez SR350 (not recommended), and a Yamaha BBG5 (very good bass), a Tobias Growler 5 (the ones made by Mike Tobias himself, not Gibson's), but i need more strings, so i need this Conklin baby.
