Ojo Dominatrix!

Project overview

This is the über-evil twin brother of the Ojo Diablo! Made to deliver the most extreme metal tones. It’s all there: massive gain, lightning speed attack, aggressive punch, super-tight low end, and clarity of chords through the entire gain range. The active 3-band EQ with and an additional Mid-range pot adds much more versatility than the original toggle.

This version does not feature the gate on board.

Introduction

There are always some pedal brands that somehow manage to fly under the radar of the gear nerds no matter what they offer sound-wise. Okko ™ is one of them, barely knew outside of Germany but fully packed with the finest engineering and tones that just deliver your modern needs.

A built-in charge pump for more headroom. (Make sure your electrolytes can handle them) a super powerful EQ and Distortion with its own voice and powerful attack. I mean… You can imagine that I build quite a lot of drive pedals, but this one ended up on my board right after I put it in the enclosure. Not even needed an artwork on the 1590BB… Just had to play it.

The original unit has a toggle for the mids, and we replaced this with a potentiometer for the ultimate control over the – for guitar elementary – mids.

Side note, there is a 15v regulator that’s pretty tall. I would solder it on the very end of the build. Right after you drilled the enclosure, so you get an idea of the best angle. Don’t make the same mistake I did. I could barely fit it in the enclosure.
