The non-reverb Princeton is an excellent low-wattage amplifier, that stays very clean throughout the volume range. A lot of players love them as a pedal platform, as they have great headroom, and sometimes can extend beyond the typical 12 watt rating. This amp shows minor signs of wear and looks great overall, with no stand out blemishes to speak of. The power cord and electrolytic caps have been replaced, along with the power resistors. A bias trimmer was added as well, which is a great help for dialing in power tube changes. On the preamp side a couple of plate resistors were changed, and one coupling cap in the tone stack, but otherwise it's all original.
