The Electro-Harmonix Black Finger pedal is an optical tube compressor bringing all the technology of a studio compressor packed into a stompbox.
Optical Tube Compressor Pedal
Studio Effects at Your Feet
Electro-Harmonix have worked hard to bring you the best optical tube compressor that can fit into a pedal.
Using the same professional-grade techniques that you’d find in revered, vintage and high-end studio compressors the Black Finger compression pedal delivers a truly professional performance level of compression.
The EHX Black Finger uses a toroidal transformer allowing for 300 volts of swing, retaining its snappy attack whilst also providing smooth and warm compression.
The Black Finger also delivers great sustain so it works fantastically well for any amplified acoustic guitar.
Optical compressors treat incoming signals with an optically controlled attenuator which is made up of a fixed resistor and a shunt opto-coupled photocell.
Unlike most attenuators, this type of attenuator is passive and so doesn’t add any electronic signature to your signal. This results in preserving your guitar tone and character with no unwanted colouring.
Gain is required to adjust the output level so that it matches that of the original level, to accomplish this an all-tube fixed gain pre-amp circuit is used.
Lamp/LED Light Source
On the EHX Black Finger pedal you’ll find a “LAMP/LED” switch. This allows you to select between the light sources that’ll drive the optical attenuator.
The LED light works very fast and is flat in frequency content – this setting is great for standard compression effects and sustain.
The LAMP option gives you a slower attack and reduced compression on treble frequencies – this works perfectly for funk chords, vocals and keyboards.
The SQSH/NORM switch directly affects the LAMP setting allowing you to choose between a normal and attack and a more “squashed”, long attack time. The SQSH setting also reduces compression in LED mode.
Professional Grade Compression Pedal
The Electro-Harmonix is a professional grade compressor pedal and works well for a multitude of applications. Perfect for use with acoustic guitar, electric guitar, bass, vocals, keys and even drums.
This pedal features an all-tube signal patch and uses two top-of-the-line 12AX7EH vacuum tubes.
With all the incredible technology of a studio compressor but in compact pedal, the Electro-Harmonix Black Finger pedal is your perfect compression solution giving you great control over your sound.
