I've just started using Aggro as part of my v2.62 bass dual tone.
After a gate and the blue comp, the signal forks to +12 pitch shift and an SVT+810+Dyn7, then back into the mixer. Nice and simple.
The other side of the path goes through analog chorus and digital delay, then through the Aggro+Hiway100+U87 with the drive at 60%, low cut at 160Hz, then into the mixer.
The footswitch stomp switch brings the Aggro in and out (bypass volume 0%), and thereby the chorus and delay (which are also individually switched). EXP-1 can be used to dial the Aggro drive back to 0 to clean up the FX split.
Not that I overthink these things, oh no, not at all :)
