The TC Electronic Flashback is a digital delay pedal with 9 distinct delay styles; a looping function; and Tone Print, an extra mode that can be loaded with downloadable artist preset. The pedal has stereo in/out, buffered or true-bypass and controls for FX level, Decay, feedback and mode plus a 3 way toggle to divide the timing.
The pedal is powered by 9V battery or standard DC pedal power. The bottom of the pedal is removable with one screw revealing the battery compartment and a pair of DIP switches. The first switch activates the buffer circuit which helps keep the signal strength consistent in a large pedal board. The second switch mutes the dry signal for use in a parallel signal chain.
Delay time can be set in two ways. First by using the delay knob, the time range is from 20 ms up to 7 seconds, except in slap mode which goes up to 300ms. Having this very long delay time available takes some getting used to, coming from analog pedals. Basically anything past 12 O’clock will be too long for anything but special effects.
The other way to set tempo is with the unique audio-tap function. Push and hold the bypass button, strum the guitar, lift your foot and the delay is in time. This is a very fast and intuitive way of setting tempo.
The toggle switch takes your delay time from 1/4 notes, to dotted 1/8th notes or 1/4″ + dotted 1/8th. When the pedal is used with dual outputs, most of the modes will have a mono output unless this third toggle position is selected.
