The Radial PZ-DI is a compact pedal that delivers efficient control of your guitar and lets you quietly feed on your stage amps, tuner and the PA system at the same time.

The Radial PZ-DI is a unique pedal designed to work with today's new breed of electric guitars and basses that employ both magnetic and piezo pickups. It allows the artist to quickly select between pickups using the onboard footswitches.

There are two channels: one for electric and one for piezo. The PZ-DI will accept either a stereo 1/4" TRS or two mono 1/4" connectors. The magnetic pickup channel is class-A buffered and equipped with Drag™ Control load correction for optimum signal transfer. This innovative feature allows the user to adjust the load on the pickup so that it sounds 'true-bypass' as if connected to an amp without the usual pops and noise associated with true-bypass pedals. The electric channel is equipped with its own stage amp output and on-off selector switch.

The piezo channel begins with three position high-pass (lo cut) and low-pass (hi-cut) filters to tame the often brittle tone that is associated with piezo transducers. For greater control, the piezo channel also features a dedicated effects loop to allow an EQ or reverb to be added without affecting the electric guitar signal path. Since many artists employ a dedicated acoustic amp on stage, the piezo channel has a separate stage amp output plus a balanced low-Z direct box output to feed the PA system. Each of these is equipped with a ground lift switch to help eliminate buzz and hum caused by ground loops. The XLR out is also equipped with a polarity reverse to help phase align the PA, monitors and on-stage sound.

Selecting channels is simply a matter of depressing the associated footswitch. Bright full-sized LEDs provide visual clarity under stage lights to show the selected channel. Even when off, the signal from both pickups are combined and sent to the tuner out for quiet on stage adjustments. The flexible design also allows it to be used as a simple on-stage instrument selector for those that want to switch between an electric guitar or bass and an acoustic or upright. Made 'Radial tough', the PZ-DI features 14 gauge steel construction for maximum durability and is finished in a rugged baked enamel finish. Powering comes from the included 15VDC supply.

PZ-DI Features:

  • Designed for guitars with magnetic and piezo pickups
  • Footswitch control over pickups for on-stage efficiency
  • Individual stage amplifier outputs for each pickup
  • Built in Radial direct box for piezo to feed sound system
  • Always 'on' buffered tuner output for quiet on-stage tuning

Three Applications of the PZ-DI (See Images):

  • Application 1 - PZ-DI stage setup with Parker® Fly™:
    A dual-output guitar, The Parker Fly® has both peizo and magnetic pickups with a TRS (Tip - Ring - Sleeve) output that allows each pickup's signal to be treated independantly.

    In this setup:
    • The guitar's TRS output is used so only a single TRS cable is needed
    • The PZ-DI 'Magnetic' input doubles as a TRS input that feeds each channel
    • Separate 'Pezio' and 'Magnetic' outputs feed separate amps
    • EQ filters and effects loop are provided for pezio channel
    • Drag™ control pickup load correction on magnetic channel for best tone
    • Direct box output feeds PA system with peizo output
    • Always-on buffered tuner out lets you tune any time, with or without mute
    • Transformer isolation, ground lift and phase switches kill noise and buzz

  • Application 2 - Fender® with dual 1/4" cables:
    Other dual output guitars, such as the Fender Acoustasonic® Telecaster® depicted here, utillise a TRS output into a 'Y' cable to allow each pickup's signal to be treated separately.

    In this setup:
    • The guitar's TRS output is 'Y'd separately into the Magtnetic in and Peizo in
    • Separate Peizio and 'Magnetic' outputs feed separate amps as in application 1
    • The PZ-DI's EQ filters give you much greater control over your acoustic sound
    • 180º polarity reverse switch lets you get both amps working in phase

  • Application 3 - with two separate instruments:
    Any two instruments can be used with the PZ-ZI, one with magnetic pickup and one with piezo. This makes instrument changes on stage a breeze. EQ and level can be setup fo beforehand so you simply mute one instrument, activate the other and boom-you're done!

    In this setup:
    • A Fender Stratocaster® is pluged into the 'Magnetic' input
    • Separate 'Magnetic' output feeds electric amp
    • A Ramirez® Classic guitar with acoustic bridge pickup is plugged into the piezo input
