For your consideration is an active dual-volume-pedal, Model HA-1, for a Baldwin Combo Electric Harpsichord. This dual volume pedal and combo amp is in very good functional and cosmetic condition. It is much rarer than the passive version; we have owned about twenty Baldwin harpsichords and have only seen three active pedal units, though we have seen over ten passive pedal units. Unlike the passive version, the active version of the Baldwin Harpsichord pedals is also a combo amp (amp + speaker) all in one. With this, you don't need a separate amp to hear your Baldwin harpsichord.
