Operation confirmed. There are no noticeable scratches, and it's in good condition. This is a convenient effector that allows you to increase or decrease the mids (high-mids/low-mids). Includes box, instruction manual, pick, and rubber feet. Thank you. Product Description: The Haunting Mids is an incredibly effective Sweepable-Mids EQ preamp that transforms any amp or pedal into a monstrous sound. By adjusting the mid-range (Mids) to boost or scoop, you can find the tone your creativity demands. The Haunting Mids has four controls: Volume, Mids, Sweep, and a Lo/Hi switch. The Volume control is a standard volume control that adjusts the volume and can boost the signal. The Mids and Sweep controls are closely related and allow you to adjust the mid-range frequencies to be boosted or scooped to their optimal state. When the Mids knob is set to the 12 o'clock position, the frequency band is neither boosted nor scooped. Turning the knob to the left of the 12 o'clock position begins to scoop the mid-range, and turning it to the right boosts it. The Sweep knob controls the frequency band to be boosted or scooped. Turning it to the left affects the low-mids, and turning it to the right affects the high-mids. The Lo/Hi switch is similar to a Q control, sharpening the peak of the frequencies affected by the Mids knob. Lo provides a soft, wide peak, and the effect of adjusting the Mids/Sweep knobs is smooth. Hi provides a sharp, steep peak, and the effect is very sharp and clear when adjusting the Mids/Sweep knobs. This pedal is excellent for adding a great mid-range tube drive to an already breaking-up amp sound, or for adjusting overly scooped distortion sounds to achieve optimal bite in various situations such as djent, blues licks (phrases), rock riffs, and lead solos. It is also excellent for adjusting amps and pedals with characteristic mid-ranges.
