Brainwaves Pitch Shifter is solidly built. The controls onboard consist of an FX selector, a wet/dry mix control, and two knobs that separately govern each voicing. A pair of metal toggles switches allow the user to select which direction the steps are shifted: up or down. Pop the back cover off, and you even have dipswitch options for switching between true/buffered bypass and kill-dry activation. Furthermore, the Brainwaves allows both mono/stereo input and output, making it an incredibly versatile option in any player’s rig.
