Debuting in 1984, the DOD Delay FX90 was DOD's 12th FX-series pedal and the last to feature "bars" graphics. Always providing great bucket brigade delay sound at an affordable price, the Delay FX90 has consistently used the analog MN3005 chip, which is also found in the famous Boss DM-2. Delay, Mix, and Repeat controls make it easy to push the FX90 to self-oscillate for a little extra infusion of crazy in your delay.
