At 3:04 Rob realizes he may not be able to fit his MXR CSP233 Micro Amp Plus on the Pedaltrain Mini.
"For amps, we used a Marshall YJM plexi 50w mode bridged over and all knobs pretty much on full. We used the MXR Carbon Copy Analog Delay and the Phase 90. For leads, I used an MXR Micro Amp + to get extra juice, and we also did a lot of experimenting with the Way Huge Supa-Puss Delay, which lets you distort the feedback. That created some really cool psychedelic stuff. For strings, I used Dunlop Electric 10-52s, and for picks, I used 1.5mm Tortex Sharps."
