Preamp Tube Shootout

[Guitarfreak]

I recently invested in a few different tubes for my amp which only has room for a single preamp tube, the rest is solid state. I thought I'd share my findings with you. I could hear and feel a pretty nominal difference while playing through the amp, but to be honest I strain to hear the difference in the recordings, maybe your experience will be different.

I recorded two DI tracks, one clean and meant to be played dirty. I sent them from Logic Pro through my PreSonus FireBox then to a Radial ProRmp into my B. K. Butler Designed amp head through a Crate 4x10 mic'd off center with an SM57 finally back into the FireBox and into Logic Pro again... got all that?

The Tubes Used:
Mystery Tube - I'm not sure what tube this is, but it's a 12ax7 that came with the amp
Ruby - 12ax7 AC5 HG+
Mullard - 12ax7
Tung-Sol - 12ax7
