I have 2 amps i'm trying these days- an Ashdown 500 EVO head and and an Ampeg SVT CL. Both i've been trying on an 8x10E Ampeg cab and a 2x15 and playing with both an american Fender P-Bass and a mexi-Fender J-Bass. I can't seem to get the volume I want with the fullness of tone I want- a big phat, smooth big bottom end sound. Strangely i can't get either to be THAT loud without seeming to get a tiny bit of bit of distortion or loss of smoothness to the notes i play- the CL is brand new so it can't be the tubes on the amp, nor could it be the cabs, as i know they aren't blown. It's odd to me that i can't a great big tone without worrying whether i'll blow the speakers. Any ideas or suggestions?
