I have an SVT-CL and a Markbass LMII. I had been using my Markbass amp way more at gigs because at 6lbs (and 500w), its much easier at 2 am to move. And, alot of places I play can be on the smaller side, so space is a concern sometimes. I think it sounds great, but, the SVT smokes it. I have been using the SVT much more lately and man it sounds so good (and "sounds louder" even though the MB is 500w at 4 ohms and the SVT is 300w). Yes its a 90lb deadlift, but the sound is worth it. I have entertained the idea of getting a smaller tube amp, like a V4B or Orange, but for now I am pretty happy with the SVT.
