Main Description

 

The Marshall JMP1 50th Anniversary is a Limited Edition 1w valve amp based on Marshall's JMP series amps that defined a generation (the 1970s!). The period correct details include the beautiful styling and simple controls of just Volume, Bass and Treble (still no master volume in sight!)

The tone is astoundingly close to the JMP amps and we'll forgive you for immmediately and insatiably playing AC/DC's Back in Black and Highway to Hell. A gain boost switch on back of the amp allows you to go from Malcolm to Angus (that's from crunchy rhythm to searing leads) and a 1w/0.1w switch means you can get ear splitting gain at a volume that won't disturb the neighbours!

This combo version features a 10" Celestion Speaker and alternative speaker outputs

Here's what Marshall say about the JMP1

To reflect the second decade of business, and a decade that will forever be remembered for its impact on rock music, the JMP1 is completely reminiscent of 1970's Marshall Era amplifiers, most notably the JMP. Featuring a tone that has more gain than the previous JTM1 along with its own unique preamp structure and rear panel gain boost switch, the JMP1 is ideal for everything from big rhythm to searing lead for fans of 1970's rock.

Although each of the five amplifiers within the 50th Anniversary One Watt range are unique, the series also have some common features; they are all made with pride at our UK factory, and will only be so during 2012 making these amplifiers limited edition. Each model will be available as both a one watt combo incorporating an 8" or 10" Celestion speaker (varying from model to model), and a one watt head. Other common features include 8 and 16 ohm speaker outputs on the heads and combos, era correct cosmetic details, a commemorative rear panel plaque, and a unique low power switch on each of the units' rear panels, allowing you to instantly take the power from 1 watt to 0.1 watt for the ultimate Marshall bedroom volume

    I saw the advert for this in a guitar mag. That Marshall were doing five limited edition runs of 1 Watt versions for each of their five decades as a semi-centenary celebration, had completely passed me by. One edition had sold out already. However, the 70s JMP that I would have gone for anyway was still available.

    I'd wanted a 1W amp for the "studio" ever since seeing the review of the Blackstar 1W. A Marshall centenary 1W was a must-have.

    The sound is excellent (although I wasn't a Marshall man; I was a Vox AC30 man), it's plenty loud enough for a room; and the look is perfect. It seems a very accurate reproduction so, for example, there's no effects loop. I'll have to figure out how to add "post-Marshalled" reverb, etc. There are a couple of back-panel extras though: a one-tenth Watt switch and a boost switch.

    I'm very pleased.

    This is the 70’s incarnation of the 50th anniversary 1 watt range, which sets out to emulate the JMP amp’s of this era. I have never had the pleasure of playing such an amp but this does sound like the rock bands of this era (i.e. Led Zep) with ease.

    It has a tight, focused overdriven sound that is highly responsive to pick attack, play lightly and it sounds like an amp on the edge of break up and play harder and you get the chunky, Marshall crunch that sounds so satisfying. Roll back on the guitars volume knob and you will get a cleaner sound.

    If you’re looking for a classic Marshall overdriven sound at a low volume then you’ve come to the right place!
