Does anyone have any experience with either of these two iso cabs or ones like the jet city...i know randall makes one like the jet city. just trying to figure out if the silent sister is worth the extra money or not. ...any isolation cab experience you can share would be helpful. its for recording because i live in an apartment. If i like the tones i get out of my amp would an isolation cab be the way to go or would something like the pod hd be a better choice for recording.
