FX67 STEREO TURBO CHORUS
FX67 STEREO TURBO CHORUS
The FX67 Stereo Turbo Chorus was introduced in early 1988 as the "top of the line" chorus effect in DOD's lineup, with a suggested list price of $140. Like the Ibanez BC9 Bi-mode Chorus (produced from 1981-84), the FX67 featured two independent chorus circuits and was best used as part of a two-amp setup. The FX67 was discontinued in mid-1990 with the introduction of the FX68 Super Stereo Chorus.

From the manual: "The new Stereo Turbo Chorus gives a rich, thick, ebuillient chorusing effect not available before from a single chorus unit. The FX 67 Stereo Turbo Chorus has two completely independent chorus circuits. These chorus circuits are varied by a unique modulation scheme and mixed together which makes a distinctive chorusing sound. This technique gives the user truly different right and left outputs from a single chorus unit. The right and left chorus circuits are derived from separate chorus circuits and do not cancel each other out if summed together. This unique chorusing effect is unduplicatable even with the use of two separate chorus units."
Technical info:

*********Pedal shows light to medium use. Pedal has some scrapes and/or chips. Comes with battery cover and rubber bottom with foil serial sticker. Very hard to come by. For best results, you should run it to another amp or monitor.
