Hey All, Just got the AC4HW1, hand wired 112, 16 ohm. It's part of my rig along with a Quilter Aviator 8. Both just great amps! I've not liked Greenbacks ever, this one is no exception. I'm also not keen on the usual suspects, Blue, alnicos, other GB clones, etc. Anyone who has put the AC4HW1 through its paces will know what I mean when I say it is bright and is really lacking bass, and the bass is trashy too with the GB. I know they break in but still not going to do it for me. I need a speaker that gives me some fatter bass, is punchy, still retains some of the "chime", and is more efficient, ie 100-103 db. Any ideas? BTW it's a sweet amp so keeping for sure, just want to tweak it. The tube change helped too. I'm not as concerned about getting a classic Vox sound per se, just want it to be a Voxy, strong tube sound, if that makes sense. Thanks for chiming in!
