※ If you are considering a purchase, please read the profile first. Official Apple sticker is attached. Purchased as a homemade pedal that produces Eric Johnson-esque sounds. After researching, it seems to be a clone of the Lovepedal Dover Drive (though I have no confirmation). I have the actual unit, and it's quite similar. Bias can be adjusted with the internal trimmer. Turning it to the left makes it sputter more. Operation confirmed with strymon ZUMA. Condition of the exterior: Please check the images. If you have any questions, please ask before purchasing.
