My current effects are a Carl Martin Quattro ver. 1 (Comp, OD, Trem, Echo) with a Carl Martin Hot Drive'n Boost Mk3 and a Carl Martin Chorus xII in the Quattro loop. The loop is serial between OD and Trem. Now I'm adding a CM 2WAH and a CM Two Faze to this setup. The wah will go in front of the Quattro, but what is the best position for the phaser?
