collapse expand iconDescription

The Marshall Studio JTM guitar combo delivers the same iconic sound as the original JTM45, but in a more compact format. The JTM combo is a welcome addition to the Studio range, offering players authentic, smooth and valve-driven break-up at lower volumes—perfect for home or studio use. Don’t let its size fool you, because the all-valve tone of the Studio JTM packs a punch. Like the original 30W head, the Studio JTM is loaded with two ECC83 preamp valves, two 5881 power amp valves and one ECC83 phase splitter, taking you right back to the renaissance of rock ’n’ roll. The Studio JTM offers the same control and versatility as older models, where simply patching the two channels together opens up a world of all-valve tonal possibility.

Ideal for creating that definitive vintage tone, the Studio JTM combo is equipped with a single 12" G12M-65 Creamback Celestion speaker. Creamback speakers handle greater power allowing for additional low-end grunt that complements the warm and vocal mid-range crunchy upper. Power switching enables you to switch effortlessly between 20W and 5W and two loudness controls mean you can play as loud as you like. Features such as a D.I. out and FX loop have also been added, bringing the JTM into the modern day.

Jumping Channels

Being a classic amplifier, the Studio JTM series is a 2-channel amplifier without traditional channel switching. Each channel has a high-sensitivity input, voiced to take a guitar with high output pickups and a low-sensitivity input, voiced for a guitar with lower output pickups having more gain and allowing you to take advantage of that increase in gain to go full rock 'n' roll. Each channel has its own tonal color and a master volume control. The Bass Mid and Treble controls are shared between the two channels.

A lot of times you will see guitar players running a short jumper cable between the two channels of the amplifier. Doing this allows you to blend the tone of the two channels with the master volume controls taking full advantage of the amplifier’s capabilities.

This is accomplished by a very simple process. Plug your guitar on the low-sensitivity input of channel 1. Connect input 2 of channel 1 to input 1 of channel 2 using an instrument patch cable. You can then blend the channels by adjusting the channel volumes of the amplifier. Try it out for yourself to open the tonal capabilities of this amp.

    I've been looking at this amp for over a year, its everything I hoped it would be. I was reluctant to crank it up in the store, but it definitely didn't disappoint me. At home its been incredible. So much I'm getting rid of all my other amps.

  • I'm sorry, but look inside....

    Needed a tube replaced when arrived, I can live with that. I looked inside and saw a Transformer made in Vietnam and a Printed Circuit Board from I'm guessing from Indonesia. Back of the AMP SAYs "Made IN England" Should say " Assembled in England " (With the cheapest parts we could find) ...I should remove that. I will say it sounds very good. Vintage tone. No master to you have to "Dime it" for OD. Wake the dead. It comes with a very good speaker. Get the Combo. It is the same as a head and 1 x12 cabinet but hundreds less. They just flip the head upwards and drop in the same cabinet. Shame that it turned out this way.

    Great cleans at bedroom levels and up. Being able to jumper inputs gives you added adjustability. This amp has become one of my favorites, and the recent price reductions made it an easier choice than before.

    This amp sounds very much like a JTM 45 albeit at much lower volume. Like the JTM 45 this amp has a depth and character unmatched by most others.

    I just test drove this amp at my local GC. I plugged in with one of the store's LP Tribute model - not sure what pickups…. No matter this amp delivered 70's Marshall tone that I have heard all my life but never have been able to replicate. W/o pedals!! I own a Catalinbread DLS. This ST20C native is far better. We're taking 5 watt with plenty of headroom. Haven't even cable jumped yet! I'm convinced. I want this amp. It's far, far more to my liking than the Origin 50 I traded a few years ago. Wish it had built in reverb but that is not a deal crusher.
