iamqman's review"Great British Amp!"

Marshall JTM612 [1995-1997]
Back in the day when Marshall made amps that sounded good and took the time needed to build high quality amps not just fast quantity amps they build this little combo. This amp is a big surprise to me because I generally don't like the combos that Marshall has come out with. The sounds very sterile and boxy to my eras. However this amp sounds just as good if not better than many boutique amps out there today.

The 612 features a one 12 inch speaker in a combo format rated at 60 watts. Same great features as the other models but will be a little looser in the low end than the 10 inch speaker version.

It boggles the mind why they decide to stop making amps like this and think that the MG series is much more worth the time and effect. Well the real reason is they make more money off the trash amps that fit to more people's budgets rather than sticking with quality amps and keeping their integrity.

I love the way this amp sounds with a nice Gibson Les Paul or Gibson SG guitars. It fits the rock tone and compliments my playing very well. This amp sounds amazing with a solid classic rock tone that can get anything from the 60's and 70's rock tones.

The tone is warm and rich full of great harmonics. I like the tone especially playing songs from AC?DC or Led Zeppelin. This amp nails those tones without any problem what so ever.


Marshall has seriously got down he tubes in recent pun intended. Their amps has a bland cold tone that sound harsh and flat whether its in your bedroom playing or even on stage. I have played most Marshall amps that are currently in production and only a few amps sound anything like the old ones.

These are not new amps so you'd have to find them on the used market. I have no idea what the going rate for one of these amps are used, but I highly recommend picking one up.

This is a really typical amp blues-rock ...
Before this amp I had known the Fender (Twin, 1000 ...), perform ENGL screamer 50, Peavy Classic 30, Laney LC 15 R, but was told that Marshall n'tait not good for clean sounds ... and I must say that this amp has a really clean sound trs soft slamming and warm ... it certainly can not compare a Twin with 2 hp, but the difference of the twin, this amp is really versatile, usable both in concert and apart (in an apartment so small volume and with all the warmth that comes from the lights ... incredible but true !!!), only 20kg and that PSE does not ruin the Owner '...
The overdrive is really excellent, with a bold yet well Dfine ...
60W lamp with all the power is!
The MODEL intrt with this is that there is no need forcment push to get the sound you want!
I'd like to try this amp with a baffle 4 hp ... wow !!!!!!!!!!


I just acqurir this amp and I'm delighted!
Ct solidity I think I worry ... Trivia: I bought a man of Lorraine, trs cool indeed, and is delivered by mail ... I turn on the amp and it works well but the power trs n'tait not quite the (at least not the 60w), I look behind and m'apperois a lamp does not work ! And shit costs more ... imprvus Jel'eteinds, dvisse protective grille lamps. One of the lamps unplugged s'tait amplification during transport! And yet the amp sounded beautifully! (And yes even with Marshall in a lamp burns out, the concert continues ...!!!)
I reconnect and now transformed into the receiver box of ... scne Yahooooooooooo!!
In addition to ringing del my expectations, it is beautiful with its Vintage look ... good finish and a whole bunch of interesting options for recording ...
Incredibly, this amp is really affordable opportunity, but rare ... more reason to throw it ... report quality-price!
I highly recommend buying this amp for fans of Hendrix, Clapton and other Led Zep ...
My Start has good hours come ...
ciao all and good research ...

Trs simple


I like the clean sound, distortion boost the bottom high volume is good, the super crunch, a real crunch as we hear on the disc blues.Je not find the sound when you put the slime fond.Je is the gain in its own fait.La distortion this amp has nothing to do with a JCM800 for example, the sound is less gras.C is what I think the JCM800, because I know a guy who has one, and putting my amp from his cot I found my sound is less grave.En JTM is the sound of the more nervous I think, and less imposing than mine JCM.Je prfre DEFINITIONS.


No regrets, my best investment these days, 600 euros occas.J good I bought the cabinet for extension in which in addition to the combo I put a vintage30.Je cons have not felt by the diff substantial differences with the original HP heirloom in rendering sonore.J 'I wanted to electroharmonix lamps with a little more gain but it produces microphonics, so be careful not to buy the lamps too Hi gain, the ECC83 or 12AX7 basic conviennet widely.

Heat vent

Adding a heat vent to the top of the cabinet, behind the handle, helps prevent overheating which is a known problem! Great sounding amp with a special clean/crunch sound as well!
