EIS is essentially a one man show, owned and operated by Bob Schleicher. Bob has played and worked on a variety of electronic keyboards since the mid-1960's but has gradually narrowed his focus to specialize in Hammond organs and Leslie speakers.

Due to ever increasing demands on his time, Bob asks that equipment requiring his attention be delivered to the Hammond Clinic. For clients outside the San Francisco Bay area, quick turnarounds on shipped equipment requiring repairs or rebuilding can be arranged. Book appointments here. EIS services include:

• Leslie amp rebuilding and model conversion
• Leslie 1 speed to 2 speed conversion
• Leslie custom bi-amplification
• custom Hammond organs and "chop-downs"
• complete repair and rebuilding of Hammond keyboards
• Hammond tonewheel generator repair
• Hammond pre-amp rebuilding and repair
• updating 56-57 Hammond pre-amps with modern tubes and built-in 122 Leslie control

To assist with some of the more common requests and questions, schematics and labels are available through this link.
