OB indicates an early 1965 - February amp.This amp was completely gone over (as all my amps are) by the guy I consider to be the best vintage amp tech in Columbus, and it has a clean bill. Sounds absolutely amazing.Footswitch is included.I am not a vintage amp expert, but am told this amp is original. I can take pics of whatever you need to see,  just send me a message.The amp currently has a new Weber in it. It will be replaced with the original speaker prior to shipping. I have 2 pics of the original speaker included in this ad.100% ready to go. I am selling off a few of my great guitars and amps to raise money for a vintage muscle car purchase. Check my other auctions for a Gibson Custom Historic ES335 P90, a blond/maple neck Custom Shop Strat, and a very rare ASAT Junior Special Custom Shop. I will also be putting up an early 60's Fender Reverb Tank and a 1966 Vibrolux Reverb. Inquire if interested...Shipping will be listed here as $75, insured FEDEX. I will charge ACTUAL SHIPPING. If teh charges are less, I will refund the difference. If it is more, I will invoice the difference. Please NOTE. I expect the $75 will be close for lower 48 states.Good luck. This is a great Princeton Reverb
