Anyone tried these two amps side-by-side? I'm pretty sure I want one, as I have been after a good hand-wired amp that nails the vintage Blackface thing. I'm just having trouble deciding which of the two I want! I guess as I'll be gigging it the Deltone might be the safe bet with the extra headroom (although it's only a couple of watts more powerful), but I like the simplicity of the single channel Columbia. Has anyone noticed any big tonal differences between the two amps? Anyone compared the two in terms of headroom etc? Thanks!
