Reverb enhances the tone and natural beauty of an acoustic guitar and Fender’s Acoustic Preverb provides that and more. Featuring three distinctly voiced-for-Acoustic-guitar reverb settings and a high-fidelity preamp, this pedal is the ultimate ambience machine. The Notch filter and polarity switch are designed to eliminate feedback while the Tilt knob allows you to control your overall EQ balance.Designed by Fender’s in-house tone gurus, the Acoustic Preverb is an all-original Fender circuit. The chassis is crafted from lightweight, durable anodized aluminum, and the LED-backlit knobs show your control settings on a dark stage at a glance.
