1967 Realistic Pro Verb, Solid state reverberation. Rare, it only appeared in one radio shack ad. This was probably due to the fact that they were cutting out their guitar line. This reverb tank was manufactured in. the USA. Sounds very good, the sound you would expect out of a vintage spring reverb. 
 
Features: 3- 1/4 inputs for, Instrument, Microphone, and foot Switch. Also has an on/off Switch, and a Reverb Mix knob. This Unit was hardwired and hand built like many old products, includes power cable and 1/4 input cable.
