Single-coil and humbucking pickups have different outputs, which can be a nightmare when playing multiple guitars through the same gear. If a guitar is used through a complex pedalboard, signal strength may also suffer due to cable capacitance. These problems are minimized with the level adjustable buffer, a great pedal that allows you to easily switch between guitars without negatively affecting your sound. This original design features Level, High Frequency, and Load controls to fine-tune your signal, along with an on-off footswitch so you can tune with ease. The tuner output allows you to keep it always on without interrupting the signal. CHARACTERISTICS Treble frequency and level control. Pedal mute for tuning. Buttons with LEDs. Fender jewel trim. Hinged magnetic 9 volt battery cover. Anodized aluminum lightweight housing
