reverb, echo, delay...
My personal perference for The breakfast is very little or no rerverb effect in the live environment. Artificial reverb interferes with natural room reflection/acoutics and lowers the intelligiblity of the music and vocals. also, the latency from the processors creates problems and can make the players sound like they are not together. long echos/delays can add vibe or feel only if they are done in the right amount. too much or too long and it can be very distracting.
Josh Dobson is the best sound guy the Breakfast have had and the band would have a hard time functioning without him. The only person I know who can make the webster theatre sound halfway decent.
