Pitch shifting and harmony are some of the most entertaining effects to play with, but most guitar pedals that deal with these kinds of effects are one-trick ponies. That's why the Behringer Ultra Shifter/Harmonist US600 is such an outstanding pedal, particularly among the more affordable stompboxes This pedal combines five different detune and harmony effects into one, including Tremolo Bar, Flutter, Detune, Harmonist, and Pitch Shifter. The Pitch Shifter and Harmony setting give you distinct doubling effects, whereas the Tremolo Bar and Flutter effects bend your sound in creative ways at the push of a switch. And if you just want to thicken up your tone, set the US600 to Detune and go nuts. And when you add an expression pedal to control the Pitch setting on the fly, you'll be amazed by the range of sounds you'll get out of the Ultra Shifter/Harmonist Ultra Shifter/Harmonist US600 Features: Real Sound Modeling (RSM) technology delivers realistic detuning and harmony effects 5 modes (Tremolo Bar, Flutter, Detune, Harmonist, and Pitch Shifter) deliver a wide range of expression Tremolo Bar effects can shift up to 2 full octaves Harmonist pitch can provide 3rds, 4ths, 5ths, 6ths, octaves, or double octaves 10-step Key select control lets you dictate which key you're playing in for intelligent harmonies Delay/Speed control adjusts the character of your effect Balance lets you blend in as much effect with your dry signal as you like Add a TRS expression pedal to control the Pitch setting on the fly Runs on standard 9V battery or optional power supply for full pedalboard integration Tech Specs Connector In: 1/4" TS, 500k Ohms Out A: 1/4" TS, 1k Ohms Out B: 1/4" TRS500k Ohms Power Battery: 9V Type Power Supply: 9V, 100mA, regulated Behringer PSU-SB USA/Canada: 120V~,60Hz Connector: 2mm DC Jack, Negative Center Dimensions (HxWxD) 2-1/8" x 2-3/4" x 4-4/5" (54 x 70 x 123mm) Weight 0.73lb (0.33kg) Packaging Info Package Weight 0.85 lb Box Dimensions (LxWxH) 6.6 x 3.7 x 2.4"
