Doepfer offer a DIY/OEM version for a 25 key basspedal (without case). It is made of two 13 keys pedals PD/3 and the MBP25 electronics. One of the two pedals has to be shortended by one key as one of the “C” keys is redundant. Fortunately the PD/3 pedals use a plastic frame and can be shortened with passable effort. In the user’s manual the shortening and wiring of the two bass pedals is described. A bit mechanical skills and suitable tools are required (soldering iron, saw, screwdriver). Both pedals have to be mounted on a common base plate and a suitable case (e.g. made of varnished wood – as shown above) can be added. The base plate and the case are not included and have to be added by the customer. These parts are not available from us.
