Tone Corset Instructions

Back to Product Page / Instructions (PDF)

Congratulations on your purchase of the Electro-Harmonix Tone Corset. The Tone Corset is an analog compressor/sustainer that allows for extreme or subtle control of the dynamics of your instrument. There are controls for setting the output volume, sustain/compression, attack, blend amount and pad switch.

Note: The TONE CORSET draws up to 9mA at 9VDC with a center negative plug or runs off a 9 Volt battery. If using an adaptor make sure to use one with the correct polarity. Failure to do so may damage your TONE CORSET and void the warranty.  Please use an Electro-Harmonix 9.6DC-200mA power supply (same as used by Boss® & Ibanez®: 9.6 Volts DC 200mA) which is sold separately.

VOLUME KNOB: Adjusts the output level of the effect

SUSTAIN KNOB: Controls the amount of the compression

ATTACK KNOB: Controls how quickly the compressor will recover

BLEND KNOB: Adjusts the mix of the dry and compressed signal set to the output

PAD SWITCH: Pads down the input signal to prevent undesirable distortion

The Footswitch selects whether the Tone Corset is engaged or in True Bypass mode. When the effect is engaged, the LED is lit.

The ¼” jack is the audio input for the Tone Corset. The input impedance is 1MΩ.

The ¼” jack is the audio out for the Tone Corset. The output impedance is 100Ω.

To change the 9-volt battery, you must remove the 4 screws on the bottom of the Tone Corset. Once the screws are removed, you can take off the bottom plate and change the battery. Please do not touch the circuit board while the bottom plate is off or you risk damaging a component. To extend battery life, disconnect the INPUT jack when the Tone Corset is not in use.

Our new EHX Strings Electro-Harmonix electric guitar strings are custom-designed to our specifications and made in the USA by a premiere string manufacturer. Each wound string is precision wrapped with round nickel-plated steel onto a high carbon, hexagon-shaped steel core. The plain strings are made from the same high carbon steel as the hex cores. The high quality steel and computer controlled winding process results in strings that intonate accurately, are better at staying in tune and vibrate evenly for maximum sustain.
