Overall ‘good’ condition. This has been stood for quite a while but we were pleasantly surprised when it powered up well! The external box has been painted black, and the handle replaced for an 80s JCM800 style handle. Internally there is a heavy amount of rust, which doesn’t affect the components, but does affect the amplifier visually. As you can see, part of the black plexiglass has broken underneath the ‘middle’ and ‘treble’ knobs.

Please have a close look at the high resolution photographs below, as these form part of our description.


Besides from the aforementioned handle, one of the transformers has either been replaced or rewound (if replaced, we believe the original cover is still there), and minor service component changes have taken place i.e. caps, resistors, etc.

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.
