I don't have any insight into the pull function on the very cool T2. But, I have a few suggestions for a good boost into the front end. In no order of personal preference:
DOD Fet Preamp - good clean boost - also works great in the FX loop for a lead boost
Boss DS-1 - good dirty boost - especially if you set up your amp / preamp with just a little grit and then kick in the DS-1 for the dirt....
Tube Screamer - sometimes overdone but consistently good
Tube Driver - the one with the contour control - I LOVE the rackmount version because it's not (yet) as expensive at the EJ model pedal.
Morley - Distortion One (I know....Morley??? But I had one and it was great as a clean boost with the distortion down and the level up)
Hope this helps.
