Fender 68 Custom Princeton Reverb Guitar Amp Combo – Black: A 12-watt all-tube guitar combo amplifier with a “silverface” design and modified circuitry for increased versatility is the Fender ’68 Custom Princeton Reverb in Black. Compared to its ’65 counterpart, it has a more aggressive, rock-oriented tone due to its single 10-inch Celestion Ten 30 speaker. It has a shared reverb/tremolo circuit, tube-driven spring reverb and tremolo on both channels, and less negative feedback for a faster gain onset and more sensitive touch. This amplifier is well-known for combining classic Fender tone with contemporary playability, making it perfect for practice, small performances, and studio settings.
