Orange TH30H 30W Guitar Amp HeadHere's a tube guitar amp head that's powerful enough for the stage and versatile enough for the studio. The Orange TH30 head gives your two channels that let you range from glassy clean to aggressively crunchy. You can choose among 7 , 15 , and 30 watt settings, so you can get the absolute most out of this amp on a loud stage, but you can also turn down the volume in the rehearsal room or studio without sacrificing tone or breakup.
