SD-1 and mosfets

arhall · January 05, 2006, 10:03:20 AM

Hi.

I'm new here and I must say this is a great place.

I'm about to modding a SD-1 and are going to test several configs.
What I would like to know more about is using mosfet's or jfets i the clipper section. Standalone or in junction with leds, diode or transistors.
Sorry if this item already been debated alot but I can't find much info about it.
I've used the searchengine here without success.

They should give a nice OD sound, far from distortion.
Used often as clipper-to-ground. And even then its soft.

IIRC Arons "Insanity Box' [one of those schematics anyway] show's 'unusual' configuration of mosfet used as clipping diodes...worth a look...

There was an extensive discussion of this a month or so back, but I'm not sure the title or what to search. John Greene and R.G. contributed substantially. Might check their posts.

Scroll down the page until 2nd R.G.'s post and read...

That is the one. Might also try the Fender SS clipping arrangement shown. It sounds pretty good.
