Keith builds in Hackney, east London. The site claims 1971 as the starting point, and Aba Shanti-I started there as an MC.

Two 4 way models in the catalogue

Enforcer EN4black4
Annihilator AN4blue3

Both are four way preamps. A 5 way Devastator circulates on his socials without appearing on the site and without published specs: if you want it, you have to write.

Beyond the preamp

The catalogue does not stop there: power amps up to 10,000 W, bins, effect units. It is one of the few workshops in the scene covering the whole chain, from source to speaker.

No prices, no crossover points

JTS publishes neither prices nor crossover frequencies: you have to write to him. On the second hand market an Enforcer goes for around £1,000 and an Annihilator around £1,500, which at least gives an order of magnitude.

Where you hear them

Lion Youth in Geneva, Mighty Oak, Inti-Fari in Italy, Nite Vybes. The lineage counts elsewhere too: several workshops built their first units from a JTS.

What I think of it

I do not get on with the early blue editions, but that is a matter of taste, and I have never tried the latest ones.

Who it is for

A sound after a unit rooted in the history of the scene, or one that wants its whole chain from the same workshop. You have to accept going through written contact to learn the price and the configuration.
