MXR Bass Chorus Deluxe is powered by analog bucket-brigade technology and has top-mounted Flanger and X-Over buttons with LED status indicators. In X-Over Mode, modulation in low frequencies is decreased. Its Bass and Treble controls cut or boost lows and highs, while its Stereo Hardwire Bypass Mode can be used with a Y-splitter cable to send the effect signal to two amplifiers, allowing the modulation to move left to right.
