Check the listing for details. Fender Smolder Acoustic Overdrive Effects Pedal. Condition: New. Listed at 179.99 USD. It’s tough to add overdrive to acoustic guitars—not only can it sound unmusical, it can also cause tone-destroying feedback. Designed specifically for use with acoustic instruments, the all-analog Fender Smolder Acoustic Overdrive effects pedal elegantly solves these issues with Fender know-how. To soften the bright attack of a piezo pickup, Fender included a Pickup Compensation control that smooths out the highs. The Drive knob controls the amount of distortion, while 3-band EQ and Filter controls let you shape your sound to taste. Fender even includes a cabinet simulation to add some flavor when plugged into a full-range acoustic amp or PA.Designed by Fender's in-house team of experts, the Smolder Acoustic Overdrive is an all-original Fender circuit.
