There have been quite a few pedals that allow you to blend some combination of overdrive and distortion with a blend pot to do so. The idea has been around probably 25 years at least as there was some Boss pedal that did so, but I can’t remember the model.

What I would like to see would be a pedal that allows you to blend a high gain distortion and a low/moderate vintage style gain overdrive or fuzz but in parallel.

The Pigtronix Distortion’s parallel approach was part of what gave me the thought, but both its overdriwe and its fuzz are both in the low to mid-gain vintage territory and it does not get modern aggressive at all.

My thoughts on what might be best would be like a EH Metal Muff and a Tonefactor Hellbilly (Pedalworx McFuzz Jr). I think they’d do a lot in parallel to get many more shades of middle ground sounds with modern bite and vintage sensitivity than pedals that are otherwise available.

But given the pedals EH already has, I think the best combination for an EH pedal (assuming no other circuits created for it) would be the Metal Muff in parallel with the Double Muff.

The problem with high gain pedals is that they have no vintage part to their sound, and blending a vintage pedal by putting it in series does NOT work. I don’t own a Double Muff, just a Metal Muff TB. Maybe someone can try it?

Is it ok to try two pedals in parallel by using a Y splitter and then a Y combiner after the pedals?
