Fender Amplifiers have a huge musical legacy that dates from the very beginning of modern popular music. Fender amplifies have a clean tonal character which is not matched by another manufacture in the world. Our Fender full revalve kits are put together after a life time of using and comparing the performance of valves in these amplifiers. The kits offer the best options drawn from original new old stock USA made valves and their modern counterparts. They are designed and put together to provide improved sonic and tonal definition with more clarity out of these legendary amplifiers. Each preamp kit is specially selected for low noise, uniform gain and tonal characteristic. All output valves have been burst tested and matched on anode current and gain.
This combination of valves provides major improvements in terms of a crystal clear top end with more extension and clarity when used clean. When pushing this amplifier into overdrive the valves combined characteristics provide a warm clear sound with excellent sustain with plenty of upper harmonics .This results in the best balance of clean headroom and smooth warm overdrive with the vintage American Sound

The Harma ECC83 STR is used in our Fender kits as is the best choice for the sparkling clean sounds that most players want from their Fender amplifiers. The mid range is very transparent which when changing pickup selection give a nice tonal variation which is lost in some other valves.
The valve responds very well to pedals and crunches up without that harsh fuzzy tone.

We have chosen the Groove Tubes 6L6GC G.E Re issue as it has the right balance of clarity and distortion when pushed in Fender amplifies. It is a faithful sounding recreation of General Electric 6L6GC incredible dynamic range, tone and large sound stage.
In clean mode, this valve provides a warm smooth sound with a very clean and open treble. In overdriven mode the valve has the right balance in terms of clarity and crunchy dynamics producing a clear creamy warm sustain.

The 6L6GC G.E reissues are our Super Premium valves which have been specially burst tested by us. We take selected GT items and in addition to GTs in house testing and distortion rating they then also undergo our own unique real world burst testing. The burst testing process involves a series of varying timed electrical signal bursts. This runs the valves under the same stress conditions that they will meet in your amplifier. All out put valves are then dual matched by us on current and gain. This will ensure that you get the best selected GT valves available anywhere in the world.

4 Specially Selected Harma ECC83 STR for position V1 V2 V4 & V5
