Whether you’re looking for a sweet lunar breeze, or the roar of an interplanetary ocean to push your tone beyond your normal confines, the ULTRA PHASE SHIFTER UP100 is ready to help you make a change for the strange.

Trip the Phase Phantastic!

With two distinctly different phase shifters built into one incredibly twisted pedal, the UP100 grants access to every conceivable shade of sonic dementia. In Mode I with the dedicated Rate and depth dials set high, you get a warped, warbling phase shift that turns your guitar into a symphony of lysergic rubber bands. If a more traditional sound suits your mood, slip into Mode II and enjoy the blissed-out shimmer of classic rock’s trippiest moments.

Easy to Use

Control the overall parameters of the effect with the dedicated Level and Res(onance) dials. The status LED lets you know when the UP100’s lucid magic is working, and a top-quality on/off switch maintains pristine signal integrity in bypass mode. Power it with either our PSU-SB DC power supply (not included) or a 9 V battery.


When your imagination tells you to step over the edge, step up to the super-affordable ULTRA PHASE SHIFTER UP100. Just one of the delightful, mind-bending stomp boxes you’ll find at your BEHRINGER dealer.
