JCM 900 Dual Reverb

[Mats A]

What do you think about the JCM 900 Dual Reverb head? I recently tried one and i liked it. But when looking at the schematic all of the first stage is IC and then there is a diode bridge for distortion. Not much valve there. But it sounds good. When the JCM 8900´s came out i had a High Gain Master Volume MkIII amp but that i didn´t like. Thin and buzzy sounding. But this Dual Reverb sounded different fatter.

There's a guy locally selling a 4500 head that I've been thinking of buying. I'm a Dave Navarro fan so I've always wanted a 900, and they're pretty cheap in this part of the world so I'll probably pick one up some day. I've always liked the sound of them but I can understand people who don't in the sense that they're a bit harsher and not as pleasing sounding as 800's. But if you like it, that's what matters.

I bought a 900 stack in 94 and sold it ten years ago when everything with diod clipping was a nono, including silver jubilees. I had a full stack 100watt 50 watter a later again a 100 watter jub sold them and the 900 as the first generally exepted attenuators became everymans thing revitalising the old plexis and 4-holers.
However the 900 have thier place in Marshall history and you can use it for many differentstyles of music. Good amp for a gigging musician but perhaps not the one and only amp I would bring to the studio.

Might get one now, in a few years they are "vintage" ...

Yesterday I bought a 2210 JCM 800 (have a 2205) for less money then the new JCM1 1 watter amp. The are the forberer of the 900 series but with a bit more growl.

Best plexi

I have two Dual Reverb Mats but I'm selling one of them since I ordered the YJM 100 so now
you know where to get one

I think they work really well, especially channel A if you use good tubes and bias them properly

Sometimes i think the 2205/2210 amps lacks a bit of top end. It´s like it was cut off. Maybe that is why John Norum is using his wah wah on solos so much to get the top end.

Got to get rid of my JVM first.

My first amp was a Marshall JCM 900 4102, which I bought in the fall of 1991. The 4102 was the 2x12 combo version of the 100w hi-gain dual reverb amp. I've always loved it. I've never compared it side-by-side with any other Marshall. I guess I'd be interested to see how it compares to the JVM 205.

Me too, my first valve amp was the dual reverb 100 watt combo and I still have it.
It's not pretty after all this years but it still works all right.

I listened to some recordings i did with different amps at some rehearsals with my band. On different occasions i had a JCM800 Split Channel 50W, Dual Reverb 100W, DSL100 and JVM410H. I must say that the Split Channel, Dual Reverb and DSL all have kind of a muffled sound. Not much attack on the strings when playing a solo. It´s like the crisp top end is cut off and if you turn up the treble it sounds very harsh and fizzy. The JVM has a bit more open sound with a crispier top end more like the YJM, Standards and 2203/2204 Master Volumes. So maybe the JVM isn´t that bad after all. It has too many knobs though

[Patrik]

Yes Mats, far to many!
