This is a modulation pedal from Alexander Pedals in the US, featuring four modes. The Dimension Chorus mode is particularly noteworthy, as there are few options available with this feature, making it a strong contender for those seeking it. Each knob has a secondary mode, allowing for more in-depth settings. Additionally, one preset can be saved for each of the four modes. Stereo output options include L/R and Dry/Wet. This is a very versatile pedal. I purchased it new last October. It has only been used indoors and is currently in excellent condition. Operation has been confirmed to be problem-free. Accessories are as shown in the photos. By adding features like Dimension, Rotary Speaker, and Pitch Shift to traditional chorus sounds, this pedal has been crafted into a new and unique effects pedal with four effect modes. ●CHO: A mode that creates everything from traditional chorus to vibrato. An additional chorus voice can be added to thicken the effect. ●DIM: A "non-wobbling" chorus mode that combines two opposing delay circuits. By adding feedback control, it can also create flanger-like chorus sounds. ●ROT: A mode that emulates a rotary speaker (Leslie speaker). Setting the mix control to maximum provides the most realistic effect. ●ICE: A mode that adds a pitch-shifted voice to the chorus and combines them. The pitch can be selected from one octave down, unison detune (slightly off-pitch from unison), perfect fifth, or one octave up. ※Please note that this is a used item, so there may be minor scratches that are difficult to see.
