I've always liked Incubus for SQ testing. Great range with very crisp highs. Especially this one in acoustic (Pardon Me, acoustic)

For more acoustic love, Iron and Wine will punish you if you dont have a clear amp and good mid range (Sodom, South GA)

Really interesting sound with a great deal of range (Imogen Heap, Hide and Seek)
