Just about managed to squeeze a fourth onto my Pedaltrain Nano. The Amp 11 is pretty much always on, set to very low gain, just to give a hint of hair to my Dr Z - I use the boost side set at noon to push it just a bit harder. The MXR is set for a thicker overdrive rather than a distortion. The Soul Bender is set really dark, and usually used with the Amp 11, so it doesn't get too fizzy. Lastly is a Moollon Tremolo, which is just a great, great pedal.
