Marshall schem

Post by dynaman »

The reissued 2203. I think it's called "2203X". I want to look at the effects loop. Just bought Ironsounds FX loop kit and it's supposed to be the same. Was wondering if it goes before or after the master.

It's the same loop used in the 1959 and 2203 reissue.

Yep, found that one. I just don't know if it's before or after the master...

Between the treble pot wiper and the master.

I've got a 2203 reissue schematic but I can't remember where I got it from so I can't point you to the link!

Ok, so the master feeds the PI, not the loop?

Whoa...Not sure how I missed it, but the reissue 2203 schem can be found at Schematicheaven. In fact the loop is AFTER the master. The loop directly feeds the PI.
