The never-ending quest for killer effects pedals is an expensive and time-consuming passion that most electric guitar players will have to endure for much of their playing careers (unless you're lucky enough to hit on the perfect setup early on, of course). Effects veteran DigiTech has developed a stompbox that could well put that quest to bed. The iStomp effects pedal effectively starts life as a blank canvas onto which the user paints a wall of sound in the shape of a downloadable effect. Just like any other stompbox, the new pedal allows for fine adjustment of tone with parameter knobs, but if you fancy a brand new flavor of distortion or a completely different reverb to the one which is resident on the pedal, you can just buy the effect from DigiTech's online store and download it onto the iStomp via your iOS device.
