Not sure you have any idea what you speak of?
I have a couple JCM 800s and I can tell you without a doubt that the sweet spot is 4 on the master volume. The power tubes are cooking......increasing the master generally just compresses things more....not what I consider ideal.
Some folks run...
My 1983 2203 is slightly modded for gain and tone......so maybe the stock ones are different, because ain't no one going to call mine thin at any volume.
My 2204 is 100% stock right down to the tubes (except v1). It sounds best with mv on 4.....BUT......it still is not thin as soon as you hit...
I have always been disappointed with cheap Asian guitars. PRS se always come and go in my house.....want to like them, but, they leave me cold.
Are these really that good?
Not sure where some of these folks lived???!?
Basically ever single bar band and major act ( with exception of Pink Floyd) that I saw in the mid to late 80s played Marshall amps...jmp or jcm or plexi.
They are the fucking sound of the 80s. Period. Yes they got into the faggoty rack effects...
