Keeley Dyno My Roto Chorus effect pedal. Operation confirmed. Includes the main unit, Japanese manual, box, warranty card (unfilled), rubber feet, sticker, and everything else that came with the purchase. It's a beautiful item with no scratches, except for Velcro on the back. Please check the photos for details. It has three modes: TRI-CHORUS, ROTARY, and ROTO FLANGER. The outstanding one is the TRI-CHORUS mode. It sounds the same as the legendary Songbird Tri Chorus used by Michael Landau, Dan Huff, Steve Lukather, etc. (in my subjective opinion). I think it's amazing that it can reproduce that sound in a mono output. Power consumption is low at 65mA, so it will work without problems with power supplied from a general power supply. Although it is a beautiful item, it is being sold as a used item, so please refrain from purchasing if you are sensitive to this. Please read the profile to prevent any trouble. Thank you very much. Excerpt from the manufacturer's description: "Dyno My Roto" was developed to reproduce the sound of 80's rack chorus in a compact pedal. Most chorus pedals are simply composed of two sounds: a dry sound and a modulated sound, but the Dyno My Roto adds another modulated sound. In addition, it has modes that reproduce the sounds of a flanger and a rotary speaker. The new rotary speaker simulator has a "Proximity" control, which was not available in previous Keeley products. This is intended to change the tone when the player changes the distance from the rotary speaker, and it can adjust the depth of the effect and the reverb-like effect. 【 Specification 】 ■Controls LEVEL, TEXTURE, RATE, DEPTH, MODE SW (TRI-CHORUS/ ROTARY/ ROTO FLANGER) ■ True-Bypass Switching ■ SIZE: Approx.
