    I have the 4100 DR and its a freaking beast. Love this amp. I also have a 800 and 1987x. The 900 with a eq in loop can produce 2203 tines and is a very versatile amp. Buy the 4100 if you get a chance. it has a halfpower switch.

    That's exactly correct. Sound thin.

    No one in an audience would notice any difference in tone. So it really doesn't matter. This is all ridiculous.

    So true about that 900 D.R. Sounds solid state unless pushed extremly loud.

    Happy JCM900 DR 4500 model owner here. Everyone that has been to my house and played on my 900 has liked it. Not that that number is astonicaly high or anything... Everyone says they like how good it sounds. While selling a guitar one time to a guy from a Craigslist ad I had, wanted to buy my 900 with the 2 guitars he bought. I wouldn't sell as its the only amp I have.

    Now would I ever sell it? Sure, I'm not dumb. But the anti 900 hate is just silly. Do I go around hating on someone for a particular "name whatever item you want"... no. That would be ignorant of me. Different people have different choices for a reason.

    This one here has been modded... but what JCM800 hasn't been modded?

    You gotta listen to this clip on studio cans/monitors. The difference is quite apparent.

    But on a typical PC/Phone speaker, its not so drastic.

    Johan had those things really screaming and attenuated- they are both mush.

    I wonder how many 800 worshipers use their amp without anything hitting the front end???

    actually I do, unless a tu12 in front counts

    using vol & tone on the guitar is the trick

    When I was playing JMP and 800 2204s, alomg with my 1987x, the only time I hit the goose was for a solo.

    I've never used a always on pedal for tone shaping.

    If I can't get my main tone out of just the amp, speakers and guitar, something needs to be replaced.

    Still have my two JCM900’s from the 90”s a 2500 head and a 4500 2x12 combo paid 225 for the head (Pawn shop)750 for the combo both mint used for literally hundreds of gigs never a letdown or problem (head re-tubed 1x) plenty of gain bulletproof both survived the drunk roadie test (Several times)the combo was a little brittle for me specially with a newer strat I played the 50 watt head thru a johnson 2x12 with celestion greenbacks on one side and the combo on the other side Both amps scream and still do after 30 years. Dont let em kid you your tone comes from your hands and your ability to hear and dial in a pleasing tone which very few people have a natural ability to do and for the rest of us takes(took) years to develop read somewhere years ago The Reverend Billy G had a hand in the design of the 900’s cause he wanted an 800 on steroids that would’nt keep burning up on the ZZTours Good health to all Roaming the hills of North Jersey

    I’ve owned a JCM 900 High Gain MKIII since 1992.
    I toured with it for 10 years.
    It sounds fucking fantastic!
    Never gave out on me.
    Still going hard.
    I get plenty of compliments on my tone.
    To me, the MKIII is an extension of the 800.
    I’m not a fan of the dual reverb version though. They are different amps.
    I never understood why people rip the 900 for having a diode for gain and they put a distortion box in front of their amp. Duh!
