Preamplifier Tubes
Preamp Tubes for Tone, Gain & Signal Shaping
Preamp tubes are responsible for shaping the tone and gain structure of a guitar amplifier. They influence clarity, breakup and overall character, making them a key component for tone control.
Common types such as 12AX7, 12AT7 and 12AU7 are widely used across many amplifier designs, offering different levels of gain and response.
Ideal for tone upgrades, replacements and experimentation, preamp tubes allow players and technicians to fine-tune the sound of an amplifier.
