Need a little advice - looking at you Jimmy. Reading the title you'd probably think i'm crazy. Last week I purchased a used V4B from the local Guitar Center - $899. It's in great condition however the power light is out. I also picked up the 212av cab. The tone is pretty sweet. However, there is a loud rattle at moderate volume from inside the head. I tightened all external screws btw. Anyway, i had my first practice with it last night and I guess it just doesn't have the power that I need. I had to push it fairly hard to keep up - the style is rock but not heavy. While I do like a little breakup/overdrive - the rig was distorting a lot - like, fart out bad. So yea, great amp but I need something more versatile as I play in a few groups ranging from softer rock, funky blues, and the previously mentioned rock (the loudest). So, I need an SVT. However, that's not in the budget and I do not want to hump around a 100 pound head. A local store has a new pf-500 on closeout (they are no longer an Ampeg dealer) for $279 but neither they or Guitar Center have PF cabs to try out. Would the pf-500 with a couple PF cabs offer up significantly more headroom and volume compared to the V4B with 212av?
