What you will learn in this video review:
Is this amp flexible for many styles?

Does it have a good warranty?

Note final track I edited... as copyright... they say: but sadly not Gary Moore? :(

Unlocking the truth about the Marshall JTM Studio ST20 and comparing with other gear - you decide.

I never expected this amp. And along it came just a few weeks ago so I ordered one for review. I bought mine from Fair Deal Music and I had that amp the very next day! Their service was excellent and the price was very good.

With the Marshall JTM Studio ST20 amplifier this amp uses 5881 tubes as opposed (at least in the UK) to EL34 which on a JTM45 I own had those EL34's fitted.

Many guys will never have played a JTM tube amplifier, let alone with those 5881 tubes, so they really won't have much of an idea about the sounds from this great little amp. And I have to say, neither will they have likely experienced the quality of the Studio series of valve amplifiers from Marshall either if they don't own one.

So in this video I wanted to show most features and benefits that the Marshall JTM ST20 has to offer, but also some of the other products out there that cost far more and frankly paled in to insignificance once you mention quality and maybe engineering prowess.

While I show you some of the things that others really never do, I do also show just how great this amp really is in most respects including some of the tones. Alas the last track someone claimed a copyright.. questionable as they were NOT Gary Moore...

I expected from the Studio series maybe a newer amp model from Marshall (TSL maybe?) after all the previously released Studio series including the SV20, the SC20 (Marshall studio classic), and the 2525, but I have to say that this amp really did surprise me; not least from its incredible flexibility of different tones and suitability to different styles available to anyone who buys one. It's not a deat* metal amp of course! But it can easily do, clean, blues, rock, heavy metal and with the right pedal maybe more.

I do show some of the pedals that I have tried with the JTM Studio ST20H and each has a different tone to it. In there are of course many tube screamers (even a hand wired one) that work great with the JTM.

From just 5w watts out or 20w watts out and that ability to balance the tones with a jumped connector makes this amp very flexible.

Its finished in the older style levant too, and you'll notice no corner protectors.

I do show the Marshall JTM1 at the Marshall museum in the video so do take a look at that priceless amp yourself and see where it all started.

Of course there's not really a Fractal Audio Axe-FX III in the JTM and make no mistake there's no JTM ST20 in the Axe-FX III anything like this one. Real 5881 tubes (valves) rule.

I have spent considerable time creating this video entirely as I said and at my own expense:
