How recent of a photo was it or are you sure it was his pedalboard? Accoring to his website's gear page, the only Boss pedals he is currently using is a Keeley modded TR-2, stock DS-1 (I assume stock, cause they mention the Keeley modded pedal, unless he has some some sort of secret mod on it) and a stock TU-2... but no mention of an MT-2...
