Electric guitar Jolana Disco

A rather rare copy of the Czechoslovak guitar Disco Jolana is for sale. It works great, but: the timbre does not work, it needs to be repaired. The kit includes a leatherette case, two strings, a cord, different attachments for it (for connecting to an amplifier, you can connect it in two ways.) Also included is the amplifier itself, made of speakers and a microlab creative subwoofer (the most melodic and clear sound)
