MultiDrive Studio Edition 

The EBS Metal Drive Studio Edition is a high-gain distortion/overdrive pedal designed for bass players who need a mean, distorted sound for modern metal music and other styles. It is a natural extension of the EBS MultiDrive, offering more gain and distortion for those who require it.

The EBS OctaBass SE has been further improved in the SE version (Studio Edition). The OctaBass from 1992 quickly established itself as THE octaver for electric basses. The classic now has an improved internal signal path, a new design and a new protection circuit against overvoltages of up to 18 volts.
