Trek II UC-1A Universal Leslie Combo Pre-Amp

I purchased the pre-amp used and sent it back to the factory (Michael at Trek II) to make sure it was working 100%.  Michael replaced the fuse holder and the speed footswitch with the quieter component that he currently uses in production.

The unit pictured above is the actual unit for sale.  The information below is from the Trek II website.  List price is $829.00 plus shipping when the unit becomes available.

The UC-1A allows most Leslie speakers to be used with a portable organ, guitar, synthesizer, or any audio source that can be fed into a standard 1/4" plug.  The UC-1A is equipped with four different outlets, one to accommodate each of the Leslie families listed below.  These four outlets may be used singularly or in any combination.

(Yes, if you happen to have a Leslie from each of the four groups, you really could play them all simultaneously with the UC-1A!)

FEATURES:

  • Foot switch tremolo control
  • Foot switch power on / off
