Just bought the fiance one of these, used at GC for $125:
Welcome to Gallien-Krueger: Power to Groove
It should sound better than the MosValve 500 she's playing through now
Any issues I need to worry about? I test drove it for about 20m, and all the pots were fine. The cab they had was pretty awesome, an old Mesa bass cab, 4x8 1x12. She's currently using a Sonic 2x10, so this should make it a nice little mini-rig
Wait, you have a bass-playing fiance? Sweet!
