Well, not really new per-say, but a combination of many many ideas that honestly just works (in my opinion).

I currently have this preamp circuit as a setting in my single ended build, but I'm sure it'll sound excellent thrown into an actual jcm800.

here is a quick video using my phone's mic (which clips):

It's a very aggressive sound; and even more so with the clipping diodes engaged; adding that solid state hair/high end to the already big tone. Using that second gain control, you can get a tone of different tones; especially so with the diodes engaged. The above video has both gains at about 12 o clock and 1 o clock respectively, bass mid and treb all around 12 o clock as well. Presc is about 1 o clock.

First part of the video has the clipping circuit off; when my hand goes into view, the clipping circuit is engaged.
