For such a simple layout, there's a lot going on with the 410. In addition to gobs of boost, there is also a "tilt" tone control, and a unique buffer scheme. When the Buffer Switch is on, it is always on, even when the pedal is in bypass. When the Buffer Switch is off, the pedal is true bypass. This allows the 410 to be used as a buffered boost, unbuffered boost, line driver, stand-alone buffer, and an always-on tone sweetener with or without buffer. More than just More Me! While the 410 is based on the vintage '70's 410, it has a lot more tricks up its sleeve.
