6L6 Valve/Tube Comparison (Groove Tube/JJ/Electro-Harmonix/Mesa Boogie/Jan Philips)

For this test we recorded in controlled conditions the different sound of 5 pairs of 6L6 valves, in a Fender Blues Deluxe (reissue) guitar amp.
We used:
Groove Tube 6L6-R
JJ/Tesia 6L6GC
Electro-Harmonix 6L6GC
Mesa Boogie 6L6STR-440
Jan Philips 6L6WGB
The audio was looped by a TC Electronic Ditto Looper before any effects using a 60th anniversary Fender Telecaster, the amps built in spring reverb and a Nobels ODR-S overdrive pedal.
