Pre-Owned Blackstone Mosfet Overdrive Pedal

While most pedals create distortion with a pair of head-to-toe diodes, the Blackstone instead employs four gain stages, each con­tributing a small amount of soft clipping. That avoids intermodula­tion and the creation of fizzy high-order harmonics, just as in the best vintage amps. Those amps sound good in large part because the distor­tion does not occur at just one point.

The cir­cuit is also un­usual in that it interacts with the induc­tance of your guitar's pickups to get its unique dynamic response. Because the guitar's pickups and controls are actually part of the input stage, you can go from a juicy lead sound to a barely-breaking twang with just the guitar's volume control.

The Mosfet Over­drive gets its distor­tion entirely on its own – it is not a "boost" pedal meant to cause distortion in your amp. It does its thing into pretty much any amp, at any volume.
