as discussed in one of @Ginsly ‘s threads about opamp muffs, i tried a few of them and none of them really seemed to be that exciting or exceed what i enjoyed about my EHX V5 opamp muff build, but this one was really good and seems to be a bit of a sleeper.
As this circuit introduces some mojo in the form of an NPN Ge output stage, i was inspired to lean into that a bit and tried out some TO-99 LF353 opamps on the breadboard build and they sounded great. NPN Ge is an MP11A, i think it was about 50-60 hfe. then i got a little excited and decided i was gonna do an oversized vero layout to accommodate 1/2W resistors and large film caps.
many thanks to @Robert for originally suggesting this circuit in that thread, and the Kinetic Fuzz schematic that I followed for the layout.
compared to an EHX V5 opamp muff circuit, this one is very similar, but seems to drive a bit harder, perhaps more aggressive sounding, and a lot more output volume. tone circuit is pretty cool too, seems a lot more pleasant than the EHX/V5 tone control.
if you like opamp muffs, definitely give this one a go.
