The MXR M-151 DoubleShot Distortion is an analog distortion pedal that allows you to switch between two different distortion sounds with a single unit, offering a wide range of distortion characters. This is a listing for the pedal itself only. No accessories such as the box are included. An AC adapter (18V) is not included. (Although I believe the sound quality changes, it worked with a 9V AC adapter in my environment.) Overall, it shows some signs of aging, but it's not in a bad condition. Please judge the condition based on the photos. I believe there are no functional issues, such as scratchiness. Below is the basic information about the pedal. Controls and Switching • Output (Output Level) Sets the volume balance for each channel. Determines the overall volume of the effect sound. • Bass / Mid / Treble (EQ) Allows you to finely adjust the balance and character of low to high frequencies. • Gain (Distortion Amount) Adjustable from light boost and crunch to high gain. • Focus Switch (per channel) Each channel is equipped with a Focus button/switch, and pressing this changes the character to a more intense one. Sound Characteristics ■ Multiple Distortion Characters in One Unit • Channel A has a strong mid-range, with a distortion that emphasizes the mid frequencies. • Channel B has a slightly more traditional and different character of distortion. The appeal is that you can use different distortion textures with the same pedal. ■ Wide Range of Sound Creation • Supports everything from bluesy overdrive to hard rock and heavy high gain. • The Focus switch changes the mid-range position and sound tendency, creating a variety of nuances. - Model: MXR DOUBLESHOT DISTORTION - Controls: OUTPUT, BASS, MID, TREB, GAIN, FOCUS (button) - Power: 18V (AC adapter) - Switches: ON/OFF, CH switching - Input Terminals: INPUT - Output Terminals: OUTPUT Thank you for viewing.
