Vintage 1970s Simms Watts AP100 100w 4×12 Amplifier Cabinet

Vintage 1970s Simms Watts AP100 100w 4×12 Amplifier Cabinet

Built like a tank in the 70s, this cabinet is a true powerhouse. Extremely rare & sought after! You’ll not find a sound like this, and a build quality to this extreme! Complete with Goodmans & Celestion speakers, and brand new castors to make this that bit more transportable.

Please note: this is pictured with the matching Simms Watts AP100 head, which is not included in this listing, but is for sale on our other items. If you’re interested in the matching set up, get in contact.

Serial Number: 2876

Impedance: 8ohms

Speakers: 2x Goodmans Audiom 12P-D, 1x Goodmans Audiom 12P, 1x Celestion G12M

Watts: 100w (3x speakers are 50w, 1x is 25w so will need to be ran at 100w safely)


Overall very good condition, with only slight wear and tear to the tolex. There has been a previous split to the corner of the cabinet, but this has been clamped and glued, making it even more secure than original. The cabinet is missing the Simms Watts front logo.


Externally original. However, the 4x speakers have been changed in the past, but sound as good, if not better, than the original Simms Watts speakers.

This item is currently listed for UK delivery only due to the size and weight. Get in contact if you’re serious about purchasing abroad.

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.
