Tips and tricks
Generally, HQ ON is best for high distortion, but has the adverse affect of post-ring. HQ ON+ is best for lower levels and doesn’t have post-ring. This is because ON+ engages a linear phase filter.
Digi mode is great for dialing in even harmonics.
I like sandwiching the crosstalk feature between an encoder and decoder instance of MSED. It gives a cool, holographic sound (see Use a holographic sound on the mixbus).
- Tube: really nice on Electric guitar.
- Desk: nice hi-fi sound. Introducing more stages seems to tuck it back a bit. It even has a transient shaper in there. This could be great for Mixing acoustic guitar and uke.

Hammerstein test

Pretty even distribution of even and odd, like Saturn 2. 1 stage, drive at 3 ! [[ sdrr2 hammerstein tube 1 stage.png ]]

3 stages ! [[ sdrr2 hammerstein tube 3 stage.png ]]
Digi
Even and odd harmonics can be dialed in independently.
Drive at 7, first 4 harmonics
