Dear Myles, Have you got an opinion on amps for straight-ahead, clean jazz tone? I love my Gilmore Jr. but clean headroom is not necessarily its strongpoint (that would be expecting a lot from 1/2 watt). I've read about the Acoustic Image Clarus heads and the AERs but they are a bit expensive for me. I'm not averse to building something but I suspect that won't be an option. Are their any used heads out there that I might keep an eye out for? My priorities here include: 1. great sound, preferrably under $400 2. light weight, preferrably under 15 lbs. 3. durability 4. price Thanks in advance. Incidentally, I ordered the GT 12AX7 Mullards for my Gilmore Jr. I'm looking forward to receiving them soon. Cheers, Alan Tomlinson
