I purchased this amp to use for practicing at home. I chose the 120W model because it has a 12” speaker. I like to play a lot of (very) dropped tunings, so having a larger woofer helps with low frequency response. For reference, the low C of drop C is ~65Hz and drop-A tuning on a 7-string goes down to 55Hz. Low E on a bass is about 41Hz. My biggest fear was the amp would be too loud for practicing without being obnoxious to anyone else in the room. Prior Line 6 amps I have owned had basically two volumes: silent and loud, with the volume knob just piling on loudness.
