Though I like an old school bass sound, I have difficulties to a sound out of an Ampeg that I like. So far I have used an old early 70's SVT and a 90's V-4B(H). Both I used with a 1x 15" cab. Maybe it is the amp/cab combination or the bass/amp combination or just my playing. The V4 is okay but not loud enough (maybe also a problem of having the wrong cab) I once used an SVT 3 Pro on an 8x10" cab, that was nice. I am thinking of getting a Weber Mywatt 200 (Hiwatt clone), I think it will fit my style better and doesn't cost as much either. Most of my basses are active (Fender US Dlx J, Gibson RD Artist and a Hamer w/EMG P/HB), so maybe those don't fit an Ampeg anyway.
