I've used it a few times since purchasing it. It works perfectly. This is a modulation guitar effects pedal that packs four effects: chorus, flanger, phaser, and tremolo. It's perfect for those who want several modulation effects but want to keep costs down, or don't need a lot of options. - Model Name: Warped Dimension - Brand: SONICAKE - Power: DC 9V - Controls: ON/OFF, DEPTH, RATE, MIX, TAP - Output Terminals: Stereo Output Included: Box, Instruction Manual (English) Thank you for looking.
