Custom Mode unlocks a totally different beast. It features a completely distinct new gain stage that was designed from the ground up for the modern metal player – that means you too, extended range downtuners! Instead of the scooped sound profile that was the order of the day in 1991, this new mode is all about mids, bringing a huge, dynamic, amp-like chunk that will turn any amp into a fire-breathing beast! This almost makes it like two distinct pedals in one.
