This is the Zahnrad 4000pre. It's a red model exclusive to Ikebe Gakki. As you can see from the appearance, the paint is peeling in several places, but there are no functional issues. I'm selling it now because I'm consolidating my effects into a multi-processor. I've used it for several years, and it gives a particularly rich and exquisite sound, especially when thumbing. The original box and the warranty card from the store (expired) are included. Please consider it! #Zahnrad #naturesound #4000pre #basseffects #guitareffects
