allright bass guru's here's a topic for you. which do you prefer and why the Tech 21 San amp RBI or the Ampeg SVP-CL? i currently own the sans amp but i wanted some backround on the svp-cl. i use an svt-3 pro as a power ap for the RBI b/c i like the grid it puts on my tone, but i have considered the svp-cl. i wasn't sure if it really differs from the internal preamp in my 3 pro though. any opinions and suggestions are welcome.
