Managed to finally try a PFT50T head coupled with a PF410HLF cab and wasn't too impressed by it. It sounded slightly too muddy for me, like it had a wet blanket over the tone. Could it just be the cab or is it the tone of the head? I accept it was in a sound booth too so maybe not representative of true gig tone. Anyway i've been thinking of getting a V4b but probably won't get to try one before i buy. Will i like it if i'm not fussed by the PFT50? Is it just the cab i tried that's "muddy"? I have an Ashdown LB30 all tube which sounds way flatter (although i'm using it with a Barefaced Supertwin 2x12 cab). BTW, i like a flat tone with occasional grind.
