Trick with the ring modulator

Use the Wah Ringmodulator before or after the stack section.

Add a zest (mix at 1 to 5%) of ring modulator to a drive sound based on a mesa dual rectifier for exemple.
The level of the ring modulator must be sufficiently low to not disrupt the notes when you're playing.
Set the frequency at your convenience for a best result.
You'll get an original drive sound.

Yes, the ring modulator is almost unplayable if it's mixed too hard,
but with a subtle mixing it could be interesting.
