This is a priceless piece of history, and we are taking your best offers.

This pair of ADA MP-1s is from the private collection of Billy Corgan.

These are the Gish preamps. The main unit that Billy used has 'STORE' markings on it. Billy would typically run this these as preamps into Marshall heads. That was the main guitar sound from 1989 through 1992. Later, during the subsequent Siamese Dream era Billy switch to the Marshall JMP-1 preamp.

This pair of ADA MP-1 rackmount preamps was used to record and tour on "Gish." These units were in Billy’s rig prior to switching to the Marshall JMP-1 preamps.

One unit has a marking by the STORE button. This would have been the main unit used with the other as a backup.
