My AC15HW works well for me. For times when I need to turn down, I can engage the master to knock the volume back a little. I was feeling lazy and took my ‘68 Custom Princeton to a gig on Friday night. I regretted it all night long. We had to keep the volume down and trying to find the sweet spot was nearly impossible. If money weren’t an issue, I would almost certainly gig with a Carr Skylark.
