I dont understand what you mean by "really enjoying the seperation between the clangy harmonic high side and blown-out wooly low end side".
Just hyped up the Mid-Fi Wave Folder! I didn't know these types of pedals even existed...The Prunes and Custard is kind of a tame version of, but cool in its own way. The Unpleasant Surprise also dips into this territory. There is also the Mid-Fi Wave Folder on the wishlist, but it needs some more hype I think.
Also, a ringer into a ringer is gnarly. There’s a variation of this idea in one pedal, the ZVex Jonny Octave, though it’s a different type of octave up.
Speaking of Octave, and Clang, there is also the Octave Clang. Super low parts count, super fun times.
At the time I built it, I wasn’t aware that this was something to consider. I must have gotten lucky, it sounded the way I expected with the first ones I grabbed and put in there.How was the build experience biasing the J201?
