Marshall JMP 2200 & vintage Celestions

I was in the market for some Celestion Greenback speakers (G12M) which are supposed to be the holy grail of speakers… together with the GH12.

Browsing on ebay… -as you do- I found someone selling this odd looking Marshall supposedly from circa 1976 which some Rola / Celestion speakers designed for Jim Marshall.

The seller was claiming that these speakers were in fact the famous GH12 -50 watts in this case- so I started doing my research, there is almost nothing about the JMP2200 all the Internet knows is that it’s a mid 1970 Marshall and it appears to be one of the first Solid State amps created by them.

I then moved on to researching the speakers, checked the serial number.. and boom! again.. 1976 Rola Celestions, I was so excited! long story short.. I went ahead and purchased the amp. It is probably the heaviest amp I’ve ever carried! after 3 days my arms are still in pain.

I plugged in my Gibson SG tinkered around with volume and… it was pure magic, the tone that comes out of this thing is unreal, I’ve owned probably around 20 Marshalls from different price brackets including of course 100% valve amps… and to me this JMP 2200 is the best thing I’ve heard, you get Ac/Dc tones without any effort, just plug in and play.

These beasts are not easy to find… but if you do see one on sale, do yourself a favour and purchase it! I paid around $180 US dollars for mine but I would’ve paid a lot more knowing it sounded this good.

Controls are pretty simple, the only thing that stands out are the inputs, it’s got 2 + 1 inputs, being bright and normal (?) -at least that’s how they sound to me- and one that combines and a volume for each.

A decent practice session

It’s a well known fact that musicians have a hard time getting a decent practice session where we live, doesn’t matter if it’s a house or a small flat you’ll always be bothering someone if you try to drive the tubes on your amp.

So we usually spend loads of money trying to find a perfect practice amp, and I’m not saying I found the perfect couple… but pretty close to it.

I purchased a Blackstar HT1-R it’s 1W with a 8″ speaker and reverb, but… it has an 12ax7 tube which makes a big difference, it’s a pre-amp tube so it won’t give you a true tube sound but this amp sounds so big! I mean… 8″ speaker but it just has loads of oomph and at really decent volume, the best thing about this amp is that it’s loud enough to be used in a full band practice session but it’s also appropriate for “bedroom practice”, and it’s not too expensive, they go used for £150 or so.

All in all I totally recommend this amp as a practice amp, it’s so much better than a small Marshall.

Marshall… Marshall… (echoes..) so… I can’t insult a Marshall and even less when I’m talking about blackstar, as you may know Blackstar was founded by ex Marshall employees.

Of course my other favourite practice amp is a Marshall.. and it’s the already mentioned on this website Class 5. this is superb… but slightly louder and you need a bigger space to drive the 10″ speaker and the full tube circuit, even if you get the model that comes with a master volume (or an attenuator) it still feels that it needs more volume to get the best out of it… I absolutely love this amp and it just screams AC/DC all over the place it’s not versatile at all.. but then who wants versatility, we only want one thing.. or maybe two… Blues and Rock!

Add this Marshall Class 5 to the practice amp list… but only if you live in a house and you got a room far away from parents and neighbours, because you’ll need to crank it! and this one can be used for a gig or practice at any time.

So there you go… my 2 favourite practice amps. Marshall for blues or rock and Blackstar if you want to blast some Megadeth from your guitar.

Marshall Class 5

The little beast.

I’ve always wanted one of these boutique looking Marshalls, I’ve had JCM 900, JTM30, etc. you name it. But this one just looks awesome.

Don’t be fooled by the fact that it’s only a 5 watt amp, this thing can scream! I’ve used in on rehearsals and on pub gigs, and it held up pretty good without any PA assistance, I’m not sure why but it’s just too damn loud.

This is the first version they released which doesn’t have a master volume so it’s practically impossible to get a nice distortion without having your neighbours call the police, Marshall later released a 2nd version with an open back and a master volume which of course allows you to get a nice distortion at practice volume.

By the time I bought this beauty I was not aware of the existence of a 2nd version so I added a master volume my self to the back of the amp, it’s not the prettiest looking mod… but hey… it does the job.

This amp combined with any of my vintage Gibson SGs creates the classic AC/DC sound, great sustain loads of harmonics, the speaker is a “specially designed” Celestion G10-F, to my taste it sounds awesome, probably a Celestion Greenback will be the choice if I wish to swap the speakers, but for now I think this is one of my all time favourite amps.
