With the power of 4 FLASHBACK 2’s and an expanded interface that offers 3 MASH switches, tap tempo, 6 slots for storing artist or custom TonePrints in 2 banks with 3 presets each, FLASHBACK 2 X4 is TC Electronic's most powerful delay machine ever. FLASHBACK 2 X4 features a colorful palette of studio-grade delays, including the all-new and improved Analog and Tape delay algorithms, which set a new standard in realism. Their hauntingly, lush Crystal algorithm, developed around our proprietary polyphonic octave algorithm from our lauded SUB ‘N’ UP Octaver, creates an other-worldly shimmer that is as inspiring – as it is spine-tingling! Plus, we’ve added a brand-new dual delay algorithm with two individual engines for intertwining 2 echo lines at the same time – for epic Gilmour-esque soundscapes. FLASHBACK 2 X4 is even backwards compatible, which means you can still use the original FLASHBACK presets you know and love.
