LR Baggs ALIGN ReverbProprietary reverb tailored specifically for acoustic instruments The Align Reverb was built from the ground up to complement the natural body dynamics and warmth of acoustic instruments that we love so much. The circuit seamlessly integrates the wet and dry signals with the effect in side chain so that it never overwhelms the original signal. We shaped the reverb with analog EQ to reflect the natural voice inherent in acoustic instruments. Additionally, the tone control adds versatility by sweeping from warm and muted to open and present. The result is an organic reverb that maintains the audiophile purity of the original signal with the controls set in any position.  reverb control blend reverb signal with unaffected signaldecay adjusts the length of the reverb tailtone sweeps a wide range of warmth, clarity and everywhere in between9 V battery or 9 V DC powering options (not included)engage footswitch for affected signal or true bypassvolume level control.
