i was playing a gig recently with these following pedals in my chain: boss TU-2 tuner, Boss DS-1, Boss SD-1, Seymour duncan pickup booster. And halfway through the night i noticed that my tone coming from my Fender amp was very Thin and cheap sounding (the same effects i notice when i put a Wah pedal in my chain!!!!) So i guess what they say about using too many boss pedals at once WILL cause some tone suck. any thoughs on this?? i guess i've learned MY lesson!
