    can someone tell me what is the original thought with it?

    just a lower volume clean channel kind of?

    what is the difference vs the high ?

    ive read some things on google, nd learnd ow to check if the inputs are "stacked" and they are not! so i guess my amps is a little less gainy than some others ...

    Ive started to use the low input as soon as im using pedals and i love it...high input sucks for pedals. but now im in the market for a new pedal and i want some tips for a similar amps to try on in the musicstore. just any clean 50 watter with celestions ?

    thanks !

    I have a 2203 (JMP).

    The low input is lower gain, more Marshall clean if that makes any sense. Might be 1 less gain stage, I don't know
    You are correct, you cannot jump the channels.
    My amp has plenty of classic rock / hard rock / early metal gain but it is definitely not Hi Gain modern metal
    99.99% of the time I used the high input. Works fine for pedal use for me. Never had a problem except with higher gain there is less headroom for boosts.

    Are you looking for a high gain pedal? Have you tried the old familiar RAT? I'm actually using a clone R.Attack by Little Bear for more high gain sound though it's still not modern metal with it. More like mid 80's metal.

    It’s actually a pretty useful input, the low one. Yes, a very usable Marshall flavored clean tone, and if you want to get two channels out of a single channel amp just add an OD to the low input clean and you’ve got clean and crunch.

    I hit my 2204 low input with a Fulltone OCD and it rocks hard, sometimes I think more so than the typical high input, if that can be believed.

    Our MF brother Alvis speaks highly of the low input on these amps and he knows tone!
