Thank you for viewing. This is a Lee Custom Amplifier 12AX7BB, a buffer & booster. It is almost unused, having been played only a few times at home after purchase. Operation has been confirmed to be normal. No accessories are included, only the main unit. Shipping is included. Non-smoking, no pets. There are no plans for price reduction at this time. If you are interested, please consider it. Below is the manufacturer's template. A buffer/booster equipped with a JJ Electronic 12AX7 (ECC83S) in an extremely small aluminum chassis, operating at an internal voltage of 100V. When the volume is at Min, it functions as a buffer. As you increase it from Min, it automatically switches to the booster circuit (up to +26dB, 20x gain). The power supply is DC9-10V. The current consumption is around 350mA maximum, so we recommend using a power supply of 400mA or more to be safe. Compared to the 12AU7BB, it distorts more easily and has a lo-fi sound with a tendency towards low frequencies. #LeeCustomAmplifier #buffer #booster #バッファー #ブースター #ギター #Guitar #effector #エフェクター #真空管 #真空管アンプ
