The Pigtronix Infinity Looper has some of the best specs I've seen in a looper yet. I feel like this NYC based company really assessed the looping community's needs when building this box. The first thing that caught my eye was the advanced sync options. Infinity’s innovative “SYNC MULTI” mode provides a multiplier function allowing the length of Loop 2 to be 1, 2, 3, 4 or 6 times the length of Loop 1. The two loops can also be run out of sync or even in SERIES, for verse / chorus song structures. Ninja style input split mode assigns Input 1 to Loop 1 and Input 2 to Loop 2, effectively allowing performers to record and overdub separate instruments on separate loops, into isolated amps simultaneously. Midi input for beat clock sync causes loop start and stop points to obey Pro Tools or any other DAW / Sequencer that outputs Midi. The audio fidelity of this device also looks impressive. This pedal incorporates discreet analog limiter stages, transparent analog pass-through and 24bit / 48kHz HD recording engine. I also really like the AUX Loop output intended to send looped audio to stage monitors. This is especially helpful for drummers to hear and stay in time. An expression pedal jack for Loop Volume allows hands free control of the overall audio output.... Click on the title for more
