Josh had used a Marshall JCM900 100 watt head dating back to 1992 on Kyuss' classic album "Blues for the Red Sun". It was used in conjunction with a Ampeg 8x10 cabinet or a pair of Ampeg guitar cabinets later on during the recording of "Welcome to Sky Valley" in June of 1993. When Kyuss toured Australia with Metallica in 1993, a pair of JCM 900s can be clearly seen behind Josh, powering a stack of 1960A and B, Marshall 4x12 cabinets, and another Ampeg 8x10.more
Around the time of recording Oasis’ first album, Noel started using Marshall heads and cabinets. The usual setup was two JCM900 heads, each one connected with the Marshall cabinet. He probably used these amps on most of the Oasis’ albums until 2000s. Those amps were used for 1994 concerts, as seen in [this](https://www.youtube.com/watch?v=Th-IHpLgH_8) video, where they are seen at 3:43 minute mark, and they are behind him the whole time. Also, Bonehead is also thought to use those amp heads.more
From Musician Magazine - September 1993 (Interview with Kim & Tanya): "I usually go through the JCM 900, but Kelley bought a new Marshall cabinet, so now I let her use it and I use an old JCM head and cabinet. I also have a Peavey Classic 50 and an old Sears Tremolo amp that we've pasted the word 'Marshall' on."more

In this interview, guitarist John 5 shows off his amp at (6:15), the Marshall JCM 900. It’s “the 100 Watt High Gain Dual Reverb, and have a beautiful white… it’s great, you know. It’s all I need. It’s just a... just does the job, and then I’m running... On the other side, I’m running the Redhead, and it’s the same thing, JCM 900. So I’m running two heads on one side and then two heads on the other side.”more

According to Anti-Flag guitarist Justin Sane in this Guitar World interview, "I use a Marshall JCM 900 Lead with a 1960 cabinet. I’ve found that if I have a really hot-wired Marshall head I can play almost any guitar and get the sound I want."

The amplifier head on the right hand side stack of Orange 4x12" cabs as seen at 2:58 in this video of Catfish and the Bottlemen playing at Reading 2015 is a Marshall JCM900 as denoted by the just visible name stamp, but also more obviously by the number of controls on the face of the amplifier head.more
I use a big pedalboard, which is where my overdrive sounds come from, so this amp is perfect for me as it has plenty of headroom and the clean channel sounds amazing!
I've occasionally used the overdrive channel in an emergency when a pedal, patch lead or something has died part way through a gig, but I've never really used it as a go-to sound. I find it lacking quite heavily and have to fiddle with the EQ controls for ages to get a really good sound from it. As both channels share the EQ controls, this is quite undesirable as I like to have the EQ all set to 12 o'clock for clean but then all over the place for overdrive so it makes switching between channels a total drag.
I find the EQ controls are very responsive, and the reverb is pretty variable for an amp as well. A lot of amps I've tried will overpower the "personality" of a guitar and make everything sound quite distinctively similar, not exactly the same of course, but similar. For example, a Fender Twin will always sounds very much like a Fender Twin with either a Les Paul or a Stratocaster. I love how the JCM900 lets any guitar's individual sound come through. I've recently started playing with a strat for the first time in years and I love how differently this amp responds to the single coils.
A very versatile amp, even if the overdrive channel leaves a bit to be desired.
I absolutely love my JCM 900. It has all the familiar Rock Tones you love. I use it for every Guitar Recording and even if you turn all the knobs at 12, it will sound good.
I have owned this amp a couple of years ago and it was an okay amp. The clean is okay and effect friendly. The gain channel needs a little punch if you want it to be aggressive
Several people don't like it, but I totally LOVE it! Specially the dirty channel, that's how distortion should sound like: full throttle way up ahead! This and a Les Paul or SG is a great marriage and the perfect couple! A must have!
