Switching from cascaded to parallel bright / dark channel?

Post by titser_marco »

Hi! Just built a plexi super lead inspired circuit and I am loving it. Been doing more reading and I discovered that later Marshalls were essentially the bright circuit feeding the dark circuit in the preamp.

I'd like to be able to switch between the two modes and I was wondering if you guys had a schematic showing this switching scheme. Thank you!

there is some layouts to be found on the metro board. I prefer switching from 1959 to 2203

Thanks! All the links are dead but at least you've directed me to another great forum!


Tried my hand over lunch and this appears to work. Could I ask for a once over from you guys and let me know if this will work?
