Well, I have two pedaltrain pro's full of effects that I have arranged. I have more, but I couldn't justify not making it all fit on the 2 PT's which is arguably still too big. I hoped to replace my volume pedal, EHX Pitchfork, EHX Ring Thing, T.C. Ditto looper, 2x Eventide H9, and Strymon Timeline as well as add some features I did not have previously, and fit all my remaining effects on just one Pedaltrain. Other effects I did not plan to replace are my Joe Bonnamossa Crybaby, EP Booster, MXR phase 90, up to 5 different OD, Dist and Fuzz pedals, Montreal Assembly Count to Five, Red Panda Particle, Boomerang Looper and Boss RC-3 looper. The more pedals I have to keep, the less chances I have of getting rid of my second PT Pro.
