Same Day Music is an
authorized Groove Tubes dealer
This tube from Russia is slightly brighter and lower gain. It offers quicker compression than GT 12AX7. Great for most Fenders, but may not be well suited for high gain Fender type amps (such as Boogie).Preamp Tubes
These tubes are used in the first, low-level stages of tube amps. There are many designs that will interchange and each has its own tone, gain, and response. The best example is the 12AX7 range that includes more than 6 options (i.e.: ECC83, 7025, and 5751). These may be interchanged without any modification to the circuit... user friendly, so experiment!
