Use it two ways: standard wireless system or pedalboard wireless with built-in tuner.
Standard Wireless Mode Use the A58 Transmitter + A58 Receiver as a complete 5.8GHz wireless system. Perfect for plug-and-play wireless from your guitar/bass to your amp or pedalboard.
Pedalboard Wireless Mode Use the A58 Transmitter + P58R Tuner Receiver as a pedal-style wireless system
Easily switch between normal wireless use and pedal-style wireless
Why do you need a P58R: A additional P58R transmitter offers greater flexibility for musicians. It pairs seamlessly with the A58 Tuner Pedal Receiver to create a complete A58 Guitar Pedal Wireless System. Moreover, having a backup P58R transmitter allows for quick instrument switching, making performances smoother and more efficient.
