Did he mean "hurt the cab" as in underpowering it, LOL?Just the other day i was at the guitar store and the clerk came over to harass me and we got to talking about the pf50t so he hooked me up to one and an ampeg 1x15. Whwn i asked to plug into the fender neo 8x10 they had, he wouldnt let me. And said it might hurt the cab...i laughed as i left, thinking that man probably will never know he lost that sale
