Snag the Joyo BanTamP 20w. This guitar amp's got more power than a chili cook-off. Comes tested, like your patience after a boy-band concert. Toss in headphones and a cord, it's practically a party in a package. Warning: you might become irresistible to groupies.

This Randall RD5 amp head's guitar riffs are as loud as your ex's complaints! Comes with a speaker cord, already tested - translation: survived a garage band's teenage tantrum. Rock on, just don't wake the neighbors.
