Walrus Audio is well-known for its pedals, but the company also has a small line of related accessories that includes the Canvas series. Besides the two Line Isolator/Direct Injection boxes already available, there’s now a third unit that’s dedicated to reamping. 

Using a custom‑wound transformer to do the necessary impedance conversion, the Canvas Passive Re-Amp is designed to take line-level signals and optimise them so that they can be fed directly into pedals or guitar amps.
