This is a self-made JML clone. It sometimes has poor contact, but when it's working properly, it makes a nice sound. I haven't used it for several years since I made it, so its condition is unknown. The case is relatively thick, so I think it's quite sturdy. 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. I recommend it to those who can fix it or are willing to compromise. 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.
