This is a self-made Jean-Raquel clone. It sometimes has poor contact, but when it works properly, it makes a nice sound. I haven't used it for several years since I made it, so its condition is unknown. The controls are, from left to right: Volume, Treble, Bass, and Gain. It can be powered by 9V DC. Due to its condition, I'm selling it as junk, with no returns or exchanges. Please consider purchasing only if you understand this. Please refrain from purchasing if you are overly concerned about details. There are no pets or smokers in the household.
