Can anyone elaborate on the quality of the two tubes especially the GT premium 12ax7 8pin that came from the BluesJr.III? Thanks all.

I took the NOS RCA 7025 that tested closest factory spec for V1 and used a new GT 12AX7-C Premium for V2. The Chinese ax7 had noticable tonal response compared to the NOS RCA 12AX7. Holy batman I'm barely touching strings this is the best tube combo I've tried yet. Unreal.
