I own the Germ4 and have played the Germ OD and I would say yes, but the controls are different; the Germ4 replaces the volts control on the OD side with a tone and volume control (probably more useful controls). They put the volt control on the distortion side. There are more germanium chips , 2 per side, the GERM OD only has one. I’m guessing that the Germ OD will be discontinued if the Germ4 sells well, it is a great pedal!

I just got my Germanium4 Big Muff and it is fantastic. The OD side is so flexible, great for those transparent, slightly gritty tones that I have been searching for, really cleans up well with the guitars volume knob. The bias and tone controls interact so much for tons of inbetween clean-dirty sounds. The distortion side is really well voiced, not quite a traditional Big Muff, more like a very aggressive overdrive sound. Here the volts and bias have an enormous impact on the nature of the dirt, the distortion doesn’t clean up with the guitar volume as well as the OD side, not really sure why, but the volts and bias controls seem to effect the degree of cleaning up that will happen with the guitar volume knob. I have to say when combining both sides the type of dirt that you get is very unique…sustain like crazy, but not really like a Big Muff, not really fuzz at all…just a really interesting flavor that I am very excited to have on my board! Oh, yeah, it will run off any 9volt 100Ma power source too!

The Double Muff essentially demands to be first in the signal chain, sounds bad with the compressor in front, I think Trey Anastasio , of the band Phish uses compression after distortion….

I just threw a new set of EHX 12ax7’s in my Black Finger, it was starting to sound grungy on higher compression settings, sounds fantastic now!

I would buy the Worms vibrato alone in a nano box, I love that effect, but the other effects…not as much.

clearly…the phase shift oscillator guantlet has been thrown down.

is it just a matter of taking the wires off of the slider switch and soldering them to the new switch? Or will this make just Muff 1 and Muff 2 instead of one and two together, sorry, I am not proficient in electronics, though I want to learn.

so does it effect the EQ/tone? I am confused….

edit-while we are on the Double Muff topic, is there a way to replace the slider mode switch to a stomp switch? This would make the Double Muff so much more flexible in a live situation.
