Vienna™ Dual Mode Analog Chorus

Part no. R800 7120
  • Old school analog bucket brigade chip
  • Two programs for quick choral changes
  • Turbo mode for extra intense effects
  • Standard 9 volt power supply operation

The Bones Vienna Chorus is a dual-mode chorus pedal that mimics the effect of a Leslie rotating speaker by allowing the guitarist to instantly transition between a moderate choral to an intense vibrato with the stomp of a footswitch. This can be particularly useful when switching the chorus between a verse and a bridge to create lush and exciting effects.

Unlike today's common digital chorus pedals, the Vienna is 'old school'. The distinctive warm tone is captured by way of a new-old-stock (NOS) Panasonic MN3007 - circa 1976 bucket brigade chip from the early days of analog delay & chorus pedal development. What makes the Vienna particularly impressive is that unlike older analog chorus pedals that were plagued with noise and hiss, the Vienna is quiet. In fact so quiet it rivals today's digital alternatives. This means that tone aficionados can finally rejoice with the character and feel of a vintage chorus pedal without the noise. Both chorus channels are equipped with individual rate and depth controls for full 2-channel performance. The effect is augmented with 'turbo mode' which introduces a proprietary oscillator waveform frequency while increasing the range. This lets you transition from a slight choral to extreme warble, tremolo or vibrato - opening the door to explore new sonic landscapes.

Optimized for pedalboards, the Vienna is super compact and employs 9V powering to suit the various DC power bricks that are now common with multi-pedal systems. (Power supply is not included). To keep mayhem under control, full size LEDs provide high-visibility status indicators for dark stages. And like all Radial products, the Vienna is built 'tough' with 14 gauge steel and baked enamel finish to handle the rigors of professional touring.

VIENNA CHORUS APPLICATIONS

Normal Pedalboard Setup

This standard setup shows a guitar connected to the Vienna Chorus and an amplifier. One would normally connect overdrive or distortion pedals before the chorus for greater effect.

Dual Amp Stage Setup

When using two amps on stage, it is customary to employ an ABY switcher like the Twin City to select between a clean amp and a distorted one. As the signal is split after the VIenna Chorus, a mono signal path is used.

Using the Vienna on Sax

For instruments such as a sax or trumpet that employ a microphone, combining the Vienna Chorus with a Radial Voco-Loco makes it possible to add guitar effects to the signal path. Add delay and overdrive for fun!
