Do different 12AX7 preamp tubes (sometimes referred to as ECC83) -and equivalents such as the 12AT7 - make any sonic difference? We try several sets in the V1 position to find out.

The guitar parts used are from me, the track is as yet untitled but may be released in future.
The guitars were recorded through my Peavey 6505+ converted from the 112 combo (and modded a bit) on red channel, with a BOO Instruments OD808. (green channel for the clean section).
The Cabinet used was a Zilla Fatbaby 1x12, and the Microphones used were an sE Electronics VR1 Voodoo Ribbon and a Shure SM57.
NO EQ WAS USED AT ALL. No compression, no nothing. If you want to EQ your guitars to fit into a mix, that's understandable but we wanted you to know what they sound like straight off the desk.
