Featuring three control knobs and a 3-way toggle switch, it offers versatile tone shaping with true bypass for signal integrity. Housed in a sturdy zinc alloy case and powered by a 9V DC adapter, this pedal is perfect for musicians seeking rich octave textures in a portable format. ## Description Features: 1.Three working modes. Using the Toggle switch located at the top of the pedal, you can choose between 3 different octave types. TOP chooses a very high end octave, the BOTTOM gives a very low octave and the BOTH option combines the two. The TOP and BOTTOM switches both encompass 2 octaves, so when you choose both, you actually have 4 octaves (provided that both oct1 and oct2 are turned up). 2.Onboard OCT 1, OCT 2 and DRY controls for precise tonal shaping. The OCT 1 and OCT 2 knobs do the same thing, but to different parts. ① OCT 1 controls the volume of the lower of the 2 octaves present while OCT 2 controls the volume of the higher octave. If you choose the ''BOTH'' switch, which uses all 4 octaves, OCT 1 will control the lowest of both and OCT 2 the highest of both. ② The DRY knob adjusts the fullness of the octave tone. turning it clockwise will create a warmer, fuller tone, while turning it counterclockwise will make a drier, harsher tone. In any amount, both ends of the knob are great for creative full octave effects. 3. True Bypass Footswitch Press once: Switch between original sound and effect sound. Press twice: Switch between fixed mode and normal mode. Longtime Press : Store the current parameters. 4.LED indicator light Green light: Normal mode, can use knob to adjust parameters. Red light: Fixed mode, effector use the fixed parameter, knob can't be use. Go out: Original sound.
