This tube has a well balanced, colorful tone with strongly defined lows, mids and smooth highs. It allows for more clean head-room than higher gain 12AX7s. In overdrive, it is smooth and strong with well defined lows and mids. When pushed into overdrive it offers clean distortion with well balanced lows and mids. The JJ 12AX7 is well suited for all types of music and playing styles. It is also highly recommended for studio pre-amps and hi-fi gear
