JCM 900 Distortion in a pedal?

Post by HydrozeenElectronics »

I found this article and I thought some good stuff might come of it. In the thread they are talking about how Marshall JCM 900's used "Bridge Rectifiers" for clipping instead of the regular LED's used in the 800's

The 900's are kind of fuzzy and I thought we might be able to capitalize in the bridge rectifiers for some home brewed fuzz pedals.

I can't find many good schematics of how to wire one up

has anyone had any experience with using a bridge rectifier in place of regular clipping diodes?

Thanks

here is the thread that talks about it.

HEre's the schematic of one of the JCM900's. The bridge rectifier is the ring of diodes between the first two preamp tubes. You'll also see a rectifier in the power section on the bottom right. This is where you usually find them.
