This unit is extremely clean. I bought it as NOS (“new old stock”), it has never left my smoke-free house while I’ve had it, and shows little sign of rack wear.

Note that this is the improved Dual DeltaFex (NOT the original DeltaFex).

I will reduce the price of this item until it sells, so if you're at all interested please add it to your watch list so you'll be notified when I drop the price. And of course feel free to make an offer at any time.

The Dual DeltaFex has two programmable effect engines that can be used in four different configurations:

• Series
• Parallel
• Dual Mono
• Summed Mono

Both Series and Parallel modes process a stereo input signal into a stereo output signal. Dual Mono mode configures the unit exactly like two separate stereo effects processors. Sum Mono works the same as Dual Mono, except it combines the two effects units into one pair of outputs.

Each engine can have one of 16 effect types:

• Plate Reverb
• Hall Reverb
• Room Reverb
• Short Delay
• Bright Delay
• Dark Delay
• Pitch Shifter
• Compressor
• Chorus
• Flanger
• Phaser
• Tremolo
• Rotary
• Distortion
• Exciter
• Karaoke (vocal eliminator)

See pic of top of unit for routing diagrams and effect details.
