Expand Your Sonic Canvas The Walrus Audio Canvas line of DI boxes and utility pedals has proved a Sweetwater favorite when it comes to straightforward operation and flexible functionality. The Canvas: Re-amp joins their revered ranks as a top-class re-amping box, packed with a plethora of workflow-enhancing features. This re-amping device boasts two inputs — one XLR and one 1/4-inch — that take your audio interface’s balanced line-level output, then convert it to an unbalanced 1/4-inch hi-Z output compatible with your amplifiers and guitar pedals. A custom-wound transformer smooths over any impedance issues, while the Re-amp’s ultra-flat 20Hz to 20kHz frequency response keeps your sound clean and uncolored, leaving all the coloring up to your favorite amps and pedals.
