Welcome to JTKM STUDIO.

Here we have a very special, and in my opinion the finest Watkins Dominator that will ever be on the market.  This is a 1959 Watkins Dominator from the JTKM STUDIO private collection (yes, I have quite a few rare guitars/amps that I've never shared with the general public nor photographed and this is one of them).  This particular example has been with me for around 5 years, prior to that it came from Dennis Marshall's private collection.  The below link is an interview with Dennis Marshall and you can see my Dominator photographed.

The Watkins Dominator is fully original aside from the usual service componants (capacitors etc) which naturally need to be changed out.  Original transformers and 10 inch Elac Speaker.  Note these is a slight cigarette burn mark near the volume text on the pinstripe panel.

The Dominator has just had a full service and is ready to go.  It sounds incredible with the most outrageous tremolo you'll ever find.  This is the amp which Marshall directly copied to create the Bluesbreaker in the latter part of the 1960's.  Why pay £10,000 for a 1960's Bluesbreaker when you can own a 1950's icon like this beauty!

Comes complete with its original red cover and the first variation of the tremolo footwitch (i.e. the gold footwitch).

These are relatively light-weight amps so I am more than happy to ship with one worldwide with UPS.  It will be expertly packaged in a custom made box with 6 inch of bubble wrap. 

As is clearly stated in our Terms & Conditions page, amps are sold strictly as-is. 

If you want the best of the best, this is it!

We accept all major credit cards at checkout.  This service is available for international buyers.

We ship worldwide, fully insured with UPS. We ship as soon as payments have cleared unless instructed to do otherwise. Buyers are usually provided with a UPS tracking number within an hour of the payment being received. We are not responsible for any loss or damage due to transit. All shipments will be expertly packaged with no expense spared.

We offer a 24 hour approval period on all guitar sales, thereafter all sales are final. Amplifiers are sold strictly as-is due to their fragile nature. We have never had a return in over 15 years. If a buyer choses to return a purchased guitar we must be notified within 24 hours. The guitar must arrive back with us in exactly the same condition and will be fully inspected. If the guitar does not return in exactly the same condition as it was sent or has been damaged due to transit your payment will not be fully refunded. The buyer is responsible for all return postage, insurance and incurred costs.
