RING THING 

Single Sideband Modulator 

 

Congratulations on your purchase of the Electro-Harmonix Ring Thing.  The Ring Thing has 
four selectable modes that utilize either frequency or pitch shift modulation: Ring 
Modulation, Single Sideband – Upper Band, Single Sideband – Lower Band and Pitch Shift. 

The Ring Modulator section builds upon the original EHX Frequency Analyzer adding to it 
selectable carrier waveforms, a sweepable filter, presets and expression pedal control. 

Single-sideband modulation is a new effect based on Ring Modulation but where only one 
band is present, making it a more harmonious effect. Finally, we have a powerful 
modulatable pitch shifter that can do detune effects, vibrato, chorus, transpose or even 

whammy when you use an external expression pedal.

  

 

Special Features of the Ring Thing: 
 

 

Four selectable modes: Ring Modulation (RM), Upper Band Modulation (UB), 
Lower Band Modulation (LB), Pitch Shift (PS). 

 

Single Sideband frequency shifter with separate simultaneous upper 
and lower sideband outputs. 

 

Automatically tune the Ring Modulator to any incoming signal by  
pressing and holding the PRESET FSW. 

 

The Ring and SSB Modulators can automatically tune to a note you play on your 
instrument 

 

Pitch shifter with range of +/- 2 octaves. 

 

Five modulation waveforms: Square, Sine, Ramp up/down, Triangle. 

 

Expression Pedal control over carrier frequency or pitch shift amount. 

 

Optional external oscillator/modulation input. 

 

Mono Input / Stereo Output in all modes.  

 

Save and load up to 9 presets. 

 

 

WARNING:

 

The Ring Thing comes equipped with an Electro-Harmonix 9.6DC-200BI 

power supply  (same as used by Boss™ & Ibanez™: 9.6 Volts DC 200mA). The Ring 

Thing requires 190mA at 9VDC with a plug that is center negative. Using the wrong AC 

adapter, even those made by Electro-Harmonix, could cause harm to the unit, the 

adapter or you. The Ring Thing does not use batteries.
