Later Break up
This Harma 12AX7WA Vintage cryo preamp upgrade kit is an answer to many players requests for a late break up ECC83/12AX7 type.
The late break 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. Ideal if you use pedals to overdrive your amplifier as the valve does not go thin and mushy and due to its late break up and nonaggressive manner remains cleaner longer.
The Harma Vintage 12AX7WA Cryo was designed by the factory to combine the two most vital characteristics of the most famous ECC83 types. The famous Mullard fat midband that produces warm and thick mid sound with excellent note the definition. The master stroke is that the Harma 12AX7WA retains the sparkle and chime that is found in the great vintage American General Electric 12AX7WA. It has the GE style large soundstage and gives the clean channel that chiming top end sparkle without being brittle or hard.
This is a specially cryogenically treated version offers improvements in top end detail giving better transparency and definition over the standard version. The mid band sees improvements in detail and warmth and the bass response become sharper and more musical. The other factor that guitarists find the major reason for choosing this valve is that it has more bite and has a smoother more harmonic distortion with later breakup.
The kit consists of 5 valves.
