re: Haunted
Been thinking about how to replicate this with only the single 5150 I currently own. I'm thinking recursive re-amping.
Recording DI track (DI1)
Re-amp DI track thru 5150 preamp > DIbox > DAW (DI1.preamped)
Re-amp (DI1.preamped) thru 5150 clean > 412s
downside I can see is that it would be very hit and miss to get an idea of how to tweak the settings without hearing the two amps chained; perhaps I can substitute another tube amp (maybe old seymour duncan tube head) for the clean section in order to dial in the 5150 for a desired preamped signal.
I also wondered how it might sound with the 5150 mated with another tube amp entirely, might be interesting. Although it occurred to me that the 5150 recursion would accentuate the tone characteristics of the 5150 by stacking the response curves. Potentially meaning the mating of other heads like a mesa/mesa may produce other interesting characters in the same fashion, or conversely mixed heads might not yield head turning results.
Sorry... caffeinated geeking
