REV II 33”, A.Obretenov signature

KD REV II 5-String – The A. Obretenov Signature Bass is a 33” scale Bass made exclusively from Alexander’s specifications and demands. The shorter scale, the selection of the wooden materials, the hardware and electronic components were all carefully, and with great detail, selected from the world’s best. They were then all carefully combined to craft this bass guitar. It has been such a pleasure and honour for me to work on this bass project – which I would describe as simplicity, efficiency and perfection.

LED lights: This feature is an achievement which took a lot of energy and hard work. The main goal was to develop two coloured lights (red and blue) that would work in synchrony, which was a challenge that my friend, Georgi Vlaev, solved in a fantastic way. He developed a pure analog 9V preamp that the LED lights require. The preamp works smoothly. Most important – it does not generate noise or frequencies that could disturb the work of the pickups or the EQ preamp.

Copper shielding protects the entire electronic box and pickups.
