I mentioned it in another thread, but I've been teaching myself Eagle to design PCBs. I've made a few smaller ones (Arrows clone, Mosfet Boost, and a couple experimental boards). The big muff is one of my favorite circuits and I finally tackled a big muff style pcb with added tone bypass switch like V3 BMPs. The original idea was to make it for a 1590bb so I could use 1/2w carbon comp resistors. Turns out my resistors were too close together, so that'll be for the next version. I think I may switch to side jacks if I use a 1590bb again because the enclosure isn't as tall as a 125b where it's easy to place the jack above/below the back of the pots. I ordered two 1590bb enclosures from Tayda and unfortunately the one used didn't have the screw holes tapped with threads. I was very irritated when I realized I couldn't screw the back plate onto the enclosure. Hopefully we have a small enough tap and die at work to add threads to it. Also I ended up pulling the power filter cap and folding it over the switch terminals because I was afraid it was going to hit the back plate. Another reason to try a 1590bb2 from Tayda for the increased height. Anyway.
Tonight I built one of these boards with Hizumitas parts values, except I used 100k pots and the added tone bypass. I really really hate drilling enclosures. I've been spoiled building Pedalpcb boards with the predrilled Tayda enclosures. The Hizumitas sounds gigantic and if you're into muffs you should consider building one. The tone bypass works really well. The 150k resistor in the tone bypass section evens out the volume difference between the tone engaged volume drop and the tone bypass. The tone control with the Hizumitas values works so well I didn't find myself reaching for the TB switch much while I jammed on it. The bypassed tone had a nice midrange, but a little lack of high end since the unfiltered/toned signal is so smooth. Still a useable sound and I'm curious as to how this pedal sounds on bass guitar.
