Groove Tubes GT-12AY7 Select Preamp Tube

The Groove Tubes GT-12AY7 Select Preamp Tube delivers outstanding and consistent performance when mixing and matching in order to get a signature tone from your amp. The 12AY7 is a low-gain tube great for harp or blues where softer, more compressed distortion at lower volumes is desired. It can also sub for a 12AX7 to lower gain and produce a warmer tone.
