DIY Effects: Homemade Blackstone Mosfet Overdive Pedal

DIY Blackstone Mosfet Overdrive pedal in a chocolate tin

It’s been a while since I had any time to build a pedal. In fact, I probably shouldn’t have taken the time to build this one…but I couldn’t resist. A friend of mine recently picked up a secondhand Blackstone Mosfet Overdrive and was raving about it. After some digging online I had to give it a try.

Without getting too technical, it’s basically a “dual channel” overdrive that allows you to toggle between 2 different gain settings in one pedal—pretty useful if you want to dial in a crunchy rhythm sound then punch up the gain for a solo. All told, I’ve been having a ton of fun with this one and recommend checking it out. Of course, for the sake of masochistic exhaustiveness, I’m going to build a similar project by the fine fellas at called the Double D (both use the same chip for a similar dual channel idea…) to compare.

That said, this is one of the rare builds where I’d almost have preferred just buying the thing. For one, it’s not just another repackaged Tubescreamer, and also the real deal is about half the size of mine and looks great. Check it out for yourself at the Blackstone Appliances page.

Oh, and I found the awesome tin at Goodwill for $0.99. Those of you who follow us on Twitter know about the excellent records and things I’m always picking up there (got a ton of great stuff today, including The Art of Noise, This Mortal Coil, The The, The Boomtown Rats and more…).
