The Mini Q-Wah was built to replicate just about any vintage wah tone and then some. It features a custom made Wilson Effects inductor designed side by side with a vintage Halo inductor. On the outside you have a Growl control for adjusting the bass and gain, and a Mid-range control for dialing the right amount of mid-range bite. Internal trimmers allow you to adjust the volume and sweep. Internal dip switches let you really dial in your tone.
