Hey guys! I had read way to much and Youtbed a lot... Ok I have a PF-800 running true a original Svt 810 from the 70's with some blown speakers (3) that I will repair all the cab in January. my set up is fine works really good but I want the PF as back up for tour and get the V4b as main. Has anyone had a comparison between them? I am more focused about headroom (volume) since booth are nice and legit to ampeg tone. I have a Vintage modified squire with bareknuckle pups and sans amp pre amp with circle K strings and its killer tone set up as main bass, I have a active 5 strings with seymour duncan pups to. I play mostly hardcore agresive music. Any input on help on pulling the string on to this amp is very welcome!
