Operation confirmed! I want to clearly differentiate the volume between backing and solo. However, I'm concerned about high-frequency loss and signal degradation when lowering the volume with a volume pedal. The Backing Stabilizer (BS-1) not only functions as a regular clean booster but also incorporates a circuit that suppresses signal degradation caused by lowering the amplifier's volume, outputting a high-quality signal. Even when the signal level sent to the amplifier is reduced, degradation is minimized, allowing you to use the amplifier with a higher volume level. By using it at a higher volume level, you can maximize the functionality of your amplifier and produce high-quality sound. There are various ways to use it. First, set the volume when bypassed as your solo volume, and set the "Backing Stabilizer" ON volume as your backing volume. You can also use it as a booster, setting the bypassed volume as your backing volume and the "Backing Stabilizer" ON volume as your solo volume. The booster function can be set to either +12dB or +6dB via an internal switch, allowing you to switch appropriately depending on your playing style. Other features include the ability to switch the input impedance between HI and LO, allowing comfortable use with both active and passive instruments. It also supports power up to 18 volts, enabling high-quality sound. Power can be supplied by a 9-volt battery or an external DC power supply ranging from 9 to 18 volts.
