The WL-20L eliminates cable tone simulation. This makes it the best choice for instruments where cable capacitance has little or no effect on the tone, such as an acoustic/electric guitar with an onboard preamp, a guitar or bass with active pickups, or a line-level device like a keytar or Roland's Aerophone digital wind instrument. The WL-20L also works great with passive pickups if you don't need the subtle treble roll-off provided by cable tone simulation.
