Kay Model 504 Tube Guitar Combo Amplifier #50881

Availability: In stock



WORKING CONDITION: Good - Tonally this amp sounds great. The volume and control settings are working properly, however, the vibrato effects are not working at all, even when engaged with a footswitch. Will likely need a bit of service to make those options fully operational. The power transformer was replaced in 1999

 Good - Considering that this is a vintage amp, there are some signs of wear. There are numerous scuffs and abrasions around the chassis of the amp. The speed knob for the vibrato control is cracked and sits loosely on the amp. Some of the metal parts are rusted as well. Otherwise, everything is well-kept with each original knob nicely intact. Overall, the physical condition is good.
