Do not overlook the EQ 73, 81, PA, and PB. These EQ's give a nice smoothness to a distorted guitar in my opinion. Don't over do it, but a little really adds a nice touch. Turn the input up and adjust output accordingly.
And don't discount those Quad plugins. Overlooked workhorses IMHO.
I almost forgot to mention the 670 comp. I love that thing on a bass guitar. Just gives it an old school richness.
Last but not in the least, the one that got me going on old school EQ's, the EQP-1A Program EQ is perhaps my favorite sounding Pultec emulation I have. And I got quite a few.
To be honest, there is not a dud in the bunch of modules for T-Racks.
