Recently, DigiTech rolled out a new stompbox called the iStomp, which lets you select digital stompboxes and effects rigs via your iPhone and use them in concert with a physical stompbox, with the option to buy more digital pedals and effects via their iStomp Shop app. And we’re giving one away! To enter, you need be a fan of Stereogum on Facebook and comment with your favorite pedal effect (or favorite effects-heavy song? COMMENT!) via Facebook Connect (do not use your ‘Gum user account on this post — we’ll have to be able to check if you are a fan of Stereogum on FB when the sweepstakes ends). The sweepstakes ends 3/21 at 6 PM EST. Please check your “Other Messages” box in a couple weeks if you enter. Good luck!
