Landgraff Dynamic Overdrive Clone Pedal 9-18V Power Supply Compatible Overdrive Booster This is a Landgraff DOD clone pedal from a handmade pedal workshop that produces and sells many clone pedals by hand. It's a TS-type OD with 3-way clipping selection, but it's also recommended as a booster. Connecting it before a multi-effects unit and leaving it on all the time will nicely increase the sound pressure. Knobs: [Top Left] Gain [Top Right] Volume [Bottom] Tone Switches: [Left] TS Mode [Center] Dumble Mode [Right] Marshall Mode There is a considerable volume difference between the switch settings, but this seems to be the same as the original. Center negative, true bypass I bought it new and used it a few times, but I am selling it because I am using other pedals. The box and instruction manual were not included when new. A battery adapter is included. There are no noticeable scratches, and it works without any problems, but returns are not accepted, so please consider purchasing only if you understand this. ※I am also selling it on other flea market sites. Therefore, it may be taken down due to a purchase on another site. Please be aware that if a purchase is made on another site at a time when I am not immediately aware, such as at night, the buyer who completed the purchase first will be given priority.※ Overdrive Booster Tube Screamer Landgraff
