BLACK FINGER

All-tube Optical Compressor

- OPERATING INSTUCTIONS -

Congratulations on your purchase of the Black Finger! The Black Finger is a warm

sounding compressor pedal useful for both guitar and bass, as well as for home

recording. This pedal features an all-tube signal path using two premium 12AX7EH

vacuum tubes. Carefully reading these instructions will ensure that you will get the

most out of your Black Finger.

Included with the Black Finger is a unique 12VAC/1000mA adapter. Use only the

adapter supplied. Using any other adapter can cause harm to you, the Black Finger

and the adapter.

- THEORY OF OPERATION -

Optical compressors work by treating an incoming signal with an optically controlled

attenuator (a type of volume control) comprised of a fixed resistor and a shunt opto-

coupled photocell. Because this attenuator is “passive”—as opposed to the more

common “active” AGC (Automatic Gain Control) compressor circuits—it doesn’t add

an electronic signature to the signal, thus preserving the tone and character of the

original sound. Some gain is needed to adjust the output level so that it matches the

original level, and this is accomplished with an all-tube fixed gain pre-amp circuit. In

general, compressors are used to sustain melody lines, minimize changes in signal

level, or add a “forward” percussive effect to instruments or drums.

- CONTROLS -

COMPRESS Knob—Varies the amount of compression from minimum (counter-

clockwise) to maximum (clockwise).

WARNING: There are extremely high voltages in the Black Finger even when

it is unplugged –DO NOT OPEN THE BLACK FINGER.

LAMP/LED Switch—Selects the light source to drive the optical attenuator. The

LED is very fast and flat in frequency content. Choose this setting for straight-ahead

compression effects and sustain. Choose LAMP for a slow attack and a reduced

compression on the treble content. This is great for funk chord playing, voice and

keyboards.

SQSH/NORM Switch—Selects between normal attack and a “squashed” long

attack time for the attenuator. This directly affects only the LAMP setting but you will

see a reduction in compression if you leave SQSH on while in LED mode.

PRE-GAIN Knob—Adjusts the amount of signal fed to the attenuator. With this

knob turned toward the minimum (counter-clockwise) position, less of the signal will

pass the compression threshold. This is one way to dial in less effect. More signal in

will mean that more of the signal will pass the compression threshold. This will

maximize the effect when the COMPRESS Knob is turned up, or clip/overdrive the

circuit if the COMPRESS Knob is turned down.

POST-GAIN Knob—Adjusts the level of the OUTPUT signal.

LEVEL LED—Gives a visual indication of the gain reduction caused by the

compressor. The brighter the LED is, the greater the compression.

STATUS LED—Lights up when the Black Finger effect is engaged. If the STATUS led

is off, the unit is in true bypass mode. The footswitch engages/disengages the effect.
