The Harma 12AX7WA Vintage and Groove Tube 6L6GC GE RI upgrade kit has been designed to give you an outstanding clean sound with midband warmth and the most Authentic American overdriven rock sound especially when pedals are used to overdrive your amplifier without going thin and mushy
The Harma 12AX7WA Vintage has been specially designed by the factory to recreate the two most vital elements of classic valve sound. The famous Mullard mid band and the outstanding top end clarity of the General Electric.
The valves late break up design allows your pre amp to be cleaner which in turn does not drive your output valves as hard allowing you to get that power amp distortion more naturally resulting in more of your amps tone.
Sonically, the Harma 12AX7WA Vintage has plenty of definition with a clear open top end chime whether played in clean or overdriven mode. The factory enhanced midband replicates the vintage Mullard producing as warm and thick mid sound with excellent note the definition.
The master stroke is that the Harma 12AX7WA does not go thin and fizzy or harden in the midland when driven with pedals. it retains the sparkle and chime and gives the overdriven sound fatness and smoothness without being brittle or hard.
Groove Tubes Super Premium valves are specially burst tested by us and matched by us in addition to GTs in house testing. This will ensure that you get the best selected GT valves available anywhere in the world.
In clean mode the GT 6L6GC GE Re issue provides a warm smooth sound with a very clean and open treble and is a faithful reproduction of the originals General Electric's tone.

This is why this valve is considered the modern bench mark when it comes to American Rock tone.
The superb way that the GT 6L6GC Re issue valve handles drive pedals is where this valve excels.
