From what I understand (and I might have gotten mixed up), the Stache is based on the GGG Tuned Muff, whilst the TFR is obviously based on the Civil War Green Muff. Now largely the differences are just in a few components, a resistor value here, a capacitor value there. But they are both Muff based fuzzes, they will react wildyl different with what you feed them.
I've got a GGG Green Muff to finish, I'll try and compare that with my Stache and Fuzz Face build asap.
If you go Stache, and want beef, have Ry put Asymmetric LEDs as one of the diode options, Big!!
