Groove Tubes GT-12AT7 Preamp Tube (ECC81) (Guitar Amp Valve)

£22.90
Product code: gro12at7ecc81

The 12AT7s make-up is very similar to the 12AX7 and can be substituted for a 12AX7 in a pinch, although it won't sound very good. Some players do prefer to use the 12AT7 in the driver stage in a Marshall for a cleaner, brighter tone. (The driver or phase inverter is the 12AX7 located nearest the power tubes.).
