Product Description

Fulltone Custom Shop That 80’s Rack Chorus

Fulltone has procured enough N.O.S. Panasonic MN3007 Analog Bucket Brigade Delay chips to build a limited production run (total 3200 units)of Custom Shop “That 80’s Rack Chorus” units. These are exact reproductions of the extremely rare and wonderful sounding rack-mount format Tri Stereo Chorus (TSC) effect sold during the 80’s under the Dyno My Piano, Songbird, and Dytronics names. I own multiples of all three version and there are slight differences between them, but according to my ears (and verified by Michael Landau) the early Dyno My Piano is “The One” and, not surprisingly, the one I have chosen to recreate. Like the early Dyno MY Piano, mine has 11 x NOS JRC4558 chips, and I chose a JFET input chip, which improves interfacability, and shows up on early to mid-period TSC’s.

Fulltone has produced many custom parts for this project, including pots, switches, transformers, and photocells, which is a huge & expensive undertaking, but just the thought of only 3200 of these ever being made with the T.E.R.C. logo one them… drawing heavily from the vintage Looney Tunes “That’s all Folks” font… puts a smile on my face.
