Fender Vintage Transition Era 1963 Princeton Combo Mod'd (Joe Satriani Private Collection)(Pre-Owned). A killer find! A Transition Era 1963 Princeton Reverb Combo. Features a Brown face circuit in blackface. VINTAGE COLLECTORS NOTE: This is a Mod'd amp. We are not advertising this as period authentic. However we are able to tell you that Master Amp Gurus Kirkwood (of Kirkwood Audio) and Ben Fargen both personally worked on "tuning" this amp for Joe. The amp has an added standby switch, a grounded 3 Prong AC line and a Push pull for bringing vibrato in and out of circuit so you dont always have your signal running thru that circuit if you dont want it. Some notes on the mods are included. So while its been "mod'd" its done by highly qualified techs and for a Player's Reason. Take advantge of Joe's efforts.
