I have the 12 oscillator JMT drone synth. I love it and constantly use it; simply running it through a distortion creates a thick wall of sound, reverb pairs very well with it too. Intuitive, reliable, pretty much exactly what I was looking for. I would love to try one of their noise synths but they are rather pricey.
I also happen to have an MS657. Imo, it is all you need when it comes to trogotronic noise synths; they are so brutally unstable that the controls on the higher models seem superfluous. It really requires time to learn how to get what sounds you want out of it, but its worth the payoff, and if you note the switch and knob positions, everything is replicable. Insane shrieks, sputtering feedback, hell you can even tease out some rudimentary beats from it. Truly a ton of fun to play with, with enormous depth. I have had it produce some utterly insane sounds paired with other gears/pedals-once during a live gig it somehow it somehow seemed to be modulating my bandmates vocals as I had one of his outs running to the input. It has a habit of overwhelming other pieces of gear, and even at zero gain it will be audible. Nelson actually just put out a new Geronimo record which I am sure will showcase his 'insect war electronics'.
