StewMac EC Expander Pedal Kit

The secret weapon of a blues god
The EC Expander is a powerful mid-boost that will instantly supercharge the tone of your pickups, pedals, and more. Now you can finally get this tone in a pedal.

This pedal kit is our take on the famous Strat MDX control Eric Clapton installed on all of his guitars. With just the turn of a knob this powerful mid-boost changed his bright and sparkly single coils into creamy vintage PAF-style humbuckers.

Don't buy your next pedal—build it!
We loved this unique circuit so much we made it into a pedal kit. Now you don't have to modify your guitar—you can instantly add this tone to any instrument. Step on the pedal and your single coils sound fuller, and humbuckers sound richer and more dynamic.

But the pedal you build is not just a one-trick-pony! With just two knobs you've got endless ways to shape your tone. Add just a touch of mids to fill out your sound, or crank it to totally change the tone of your amp. And it stacks well with your favorite overdrive or distortion pedal for added flexibility. If you've got some drive or fuzz pedals that just turn to mush in the mix, adding some mids from the EC Expander will make these pedals come alive.

It's more than just a schematic
We include everything you need to build your new pedal:

  • Top quality components from resistors to switch
  • Road-worthy rugged metal enclosure with all holes pre-drilled
  • Bare or powder coated white finish
  • 3PDT breakout board for low noise
  • Input, output, and power jacks rear mounted for easy cable routing
  • True bypass switch
  • Custom printed labels
