I have the SW 65 one, got it from SL sale 50% off. Wanted to get the SW35 but well was a bit too late n only the SW 65 one is available tts y i got it. My impressions is that it seems a bit underpowered for a bass amp i guess, dont have that much oomph but well its meant to be a practice bass amp so gotta be a bit fair. The amp has a good tone to it great for funk. It emphasizes upper mids a lot. Not much on the bottom end, so its great for a funk (slap tone). Basic bass thump can be achieved by dimming the bass tone knob.
The eq on the bass is quite powerful i guess, although i prefer keeping it flat and control the eq on the bass. Usually i just balance btw the 2 J pickups w more vol on the pickup closer to the neck for more thick tone. W the amp setting on flat it gives a smooth warm tone.
Still gassing for an ampeg, hehehe mabbe get the ampeg portabass head n cab later onz,...
