Ok I was unaware of that, I can get 80’s hard rock and 70’s RockOnly the code 100H and 100C have FX loops on them. It also seems that they're not selling very well and are being discontinued by Marshall as most large retailers and etailers aren't re stocking them.
My thought on the origin series is that it's between the Plexi type (older)amp series and the JCM800 as the gain is a little more than the plexi but less than the 800 and priced about where the DSL series of similar power is.
with mine just bye using an SD1 and mxr10 band eq!
I love my origin’s.
