Vintage 1979 Marshall JMP Super Bass 100w Valve Amplifier Head

Vintage 1979 Marshall JMP Super Bass 100w Valve Amplifier Head

This is one of the greats – a 1979 Marshall Super Bass 100w! Near enough totally original and in great condition. This particular version dates to 30th January 1979, and has a few light marks to the tolex, most notability underneath as pictured. It is also missing the cap on the presence knob. Please ignore the voltage selector on the pictures as it has been sorted to still run as it should, with the option of international voltages. Internally it has the original Daly capacitors, and transformers, and has a matched set of 3x ECC83 valves, and 4x EL34s – two of which are Mullard, the outer two are replacements. It is an amazing example of this – near enough completely untouched and unmolested. You’ll struggle to find a purer example.

Serial Number: 00731L

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.

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.
