Start with the Red Squeeze (sens around 6 and no level boost) into USDeluxeNrm (=Fender Twin) (drive around 4) into Adriatic Delay (=Boss DM+) with short delay time and low feedback (for a slapback) into any one of the reverbs (but I use a TC Electronics Hall of Fame in the Effects Loop at the end of my chain). Let us know if this helps!
