This is a set of the EBK-SHO Booster and EBK-LS&RL Overdrive. These were custom-made over 10 years ago. I've completely switched to a multi-effects unit, so I'm offering these for sale in the hopes that someone else can use them. The booster is a clean type that can increase the volume without significantly altering the tone. There may be some crackling sounds when turning the knob, but this is normal. The overdrive is powerful and has a built-in level-adjustable buffer. When the gain is increased, it becomes a wild type with a fuzz-like roughness. The buffer can be used even without engaging the drive circuit, so it can also be used as a buffer pedal. The lettering on the surface is printed with stickers, and the color may fade if rubbed strongly, so I will sell them as they are.
