1 wyowill 6 months ago Traded a 4 year old Princeton Reverb Reissue for this 64 Ampeg Reverberocket. Has a three prong cord, but the tubes (octal pre amp, 7591 power) all are USA made Ampeg branded. Haven't pulled the back off to see if it's been serviced.Have only played it for a bit, but so far, I'm loving it. Nice smooth overdrive, much tighter lows than the PRRI, trem and verb to die for. A bit warmer sounding than the Fender.
