So this looks cool, but I think there is an issue with the electronics. The bass and treble cut and boost switches appear to be sheared off. I would have the new owner send the electronics here for repair and RF upgrade. That way we can fix the switches, test it all out and make sure it works quietly in all playing environments. When we do an upgrade we also change the IS for the quieter low-drain model that's available now (the original low-drain ones were quiet noisy, so these electronics probably have to get the battery changed every month or so). Another thing we do on the upgrade is to increase the maximum available output.
