If you had to choose between the 2, would you pick a Micro VR head or a solid state SVT350 or 450 head? Everyone should own a P-bass, right? Everyone should own an Ampeg at one point too. I have had the PF500 and had issues with it cutting out, going into protect, etc. Prefer the look of the SVT style box head. Not looking to shell out for a tube amp. Will maybe get 4 or 5 gigs a year with either a 4 ohm Berg 2x12 or 4 ohm Berg 410.
