So true... the 2203 in particular. But also the 1987 (both model number references)
If you have Facebook, here's the proper;y named Marshall JMP1. I'm using it on Overdrive 1, all tones at center (0) gain on 20, master on 13. Direct into Pro Tools. Only a slight delay. Otherwise, stock 1987 Les Paul Custom into a stock JMP1 preamp.
Not the greatest playing, just one take in a long succession of takes aiming for perfection
