I'm temporarily offering this at a reduced price. This is an effects pedal designed to emulate the sound of semi-hollow and full-hollow body guitars with a solid body guitar. Settings 1 and 2 provide a clean boost. Settings 3 and 4 give a sound similar to a semi-hollow body. Settings 5 and 6 give a sound similar to a full-hollow body. The higher the number, the fuller the sound. This is a very flavorful effects pedal. As a booster, it has good clarity, and from setting 3 onwards, you can experience the rustic and hollow feel of semi-hollow and full-hollow guitars. I didn't notice it much, but I sometimes felt a slight scratchiness in the volume control. This is a rare item these days, so how about taking this opportunity?
