Handmade in beautiful Akron, OH!

I love Tonebenders - they all have their own vibe and each MK has about a million different flavors.

This is our take on the MKIII. I don't think the MKIII gets enough love, but in it's heyday tweaks on this circuit showed up everywhere - Carlsbro Fuzz, Park Fuzz Sound, Rotosound Fuzz Box.

Our build follows the OG MKIII pretty closely and features NOS Russian Germanium transistors and clipping diodes.

We've also used our custom power inverter board, so you can use a standard +9V power supply on this old school, true to form -9V circuit. How cool is that?

We round out our build with Rean/Neutrik jacks, lead free solder, and old fashioned cloth covered wires.

She really is a beaut.
