This Ampeg Gemini G-12 amplifier is in Very Good Condition for it's ageand works great for Guitar or Harmonica if you are looking for a good clean tone. These were widely used back in the day by Jazz Guitarists because of the clean tone.
The amplifier has an interesting tube line-up with three 12AX7 tubes, one 6CQ7, one 7199 and a pair of 7591A Power Tubes to provide 22W of Great Tone!
The front panel has controls for the tremolo speed and intensity, Channel 1 VT&B, Channel 2 VT&B and reverb saturation. There are 2 inputs for each channel (guitar and accordion) a power toggle switch and fuse holder and a power light also included on the front panel.
The original speaker has been replaced with a 12" JBL Signature Speaker and the power cord has been replaced with a properly grounded 3-prong cord for safety.
A permanently attached footswitch allows you to turn both Tremolo and Echo effects on and off easily.
Overall this amplifier is in great condition and works perfectly on both channels. The tremolo and reverb both work perfectly as well.
There are a few minor nicks and cuts but it looks pretty good for an amp that is getting close to 60 years old. It is solidly constructed and will make someone a great amplifier which will probably last another 60 years.
