Techno-FA Optical Phaser

"This stereo SviSound Synthboost is the perfect pedal for all keyboard players who need an increase in db during their performance, especially in the context of pedal queues that with their compressions take away volume from the synths. The total clean SviSound SynthBoost stereo pedal gives you total control of your volume in studio and on stage!!!"
