Another one overpriced pedal, looks like many other with minor changes in diode clipping stage. Somewhere I read it's optimised for .012 strings! LOL

I thought he said something like leaving the first buffer out made it more " interactive " or responsive
To the gtr volume control or something like that.
Curious combo of clipping diodes, one of everything for good measure?

Doubt it.

When you use GE's in the feedbackloop there's little level left and cliping kicks in way too soon. Lifting the GE with a SI diode will give you the clipping characteristic of a GE diode but lifted with the forward drop voltage of an SI diode. In this case the shottkey will be somewhat lower than the normal SI resulting is assymetrical clipping with a GE characteristic.

That sounds like something done with thought,
I would guess all his employee's tell him he has golden ears, but I like some of the ft stuff, own some myself
His latest booster with " big " germanium diodes and more sanded I.C.'s seems as much an attempt to attain
" Klone Mystique status " [ KMS ] it's an interesting addition to the booster collection, not a bad price when bought with the o/d combo but
I bet it burns him that he doesn't have that kind of legend of the Klone,
