Vintage 1979 Marshall JMP 50 Master Model MK2 Lead Amplifier

Vintage 1979 Marshall JMP 50 Master Model MK2 Lead Amplifier

One of the last great Marshall JMP amplifiers, this ‘Master Volume’ really is a beast! It has the same chassis layout as the heads, but with two Celestion speakers. With it being the 50w version, it is a lot more manageable volume than those crazy loud 100w. The two channels – low and high – give a great range, with the first channel nice and clean, and the second that classic JMP distortion. Very few changes to this, except a couple of small components. All original transformers dated 1979, as pictured. The condition is brilliant. There are a couple of small scuffs to the tolex, as pictured, otherwise top condition. Also includes a perfect fitted cover. Please check out the in-depth pictures below as these form part of our description.

This amplifier has been serviced to a playable & safe standard, by one of our leading amp techs. To find out more about what our service includes, please check out our terms and conditions before purchasing.

At The Music Locker we will do all we can for you to get the instrument you want. You’re more than welcome to come and have a play on this, coupled with one of our vintage guitars!

The Music Locker prides itself on offering vintage and collectable pre-owned instruments and equipment (the Products).

We take all reasonable steps to ensure the equipment has been inspected by a competent person in the UK to ensure it complies with UK safety standards. This may mean it does not comply with the current standards in the country in which it will be subsequently used. It is the purchasers’ responsibility to ensure it is inspected by a competent person knowledgeable with the relevant electrical safety standards within that country, prior to connecting to any live electrical circuit.

It is the philosophy of The Music Locker to keep all items as original as possible, only changing original components when absolutely necessary. This includes valves, capacitors, transformers, potentiometers, frets, etc. This gives the buyer the option of tailoring to their exact needs, and may mean that the item is not operating at optimum performance levels. Therefore, your personal preference may differ, depending on your circumstances (i.e. collector or musician), and you may decide to service the item in more depth upon receiving.

The Music Locker cannot accept responsibility for any costs of refurbishment to a standard different to the one advertised.
