Independent shopping perspective
The Korena take
WL-20L is the cable-tone-simulation-free version of BOSS’s WL-20 wireless system. It keeps the compact, plug-and-play wireless approach while omitting the slight treble roll-off associated with the WL-20’s simulated 10-foot cable effect. That makes it a direct fit for acoustic/electric guitars with onboard preamps, active-pickup guitars or basses, and line-level devices such as a keytar or Roland Aerophone digital wind instrument. It can also be used with passive pickups when that cable-tone effect is not wanted.
Strong match
Who this is for
- Acoustic/electric guitar rigs that use an onboard preamp.
- Active-pickup guitar or bass setups that do not need cable tone simulation.
- Line-level devices such as a keytar or Roland Aerophone digital wind instrument.
Consider the trade-offs
When to look elsewhere
- Players who want the subtle treble roll-off produced by WL-20 cable tone simulation.
