CLEAN SECTION

The Clean Preamp is designed to imitate (and surpass) all of the “classic” guitar amp preamps. The BlackVerb gives the player the ability to do two unique things:

1. Shift the midrange center point frequency.

2. Select the amount of Bass gain appropriate to your guitar choice (via Humbucker/Single coil switch covered in the Rear Panel Section of the manual).

Bright Switch – Center = OFF, Down = sound of new strings, Up = normal Bright response.

Volume – Typical setting is between 3 and 5 but experimentation is encouraged. Pulls to switch the Tweed Boost to a more conventional Mid Boost

Treble Control - Adjusts highs (also upper midrange when the Tweed Boost is engaged).

Middle Control – Controls the amount of Midrange frequencies, somewhat interactive with the Bass Control. Pulls to enable “Deep” which scoops some midrange frequencies and emphasizes Bass (makes your electric sound more like an acoustic).

Bass Control – Sets the amount of low end. Can be rotated to zero where it clicks off for a full tone stack lift.

Mode Selector – A six position rotary switch, it steps through 5 progressively fatter positions of the midrange center frequency and achieves maximum fat midrange by engaging Tweed Boost in position 6.

DRIVE SECTION

The Drive section controls the amount of character to add to the clean tone. The section’s range of effect can be just a hint of early break up or a full on aggressive heavy metal distortion.

Gain Control – Bypasses the section when rotated to zero, this control sets the amount of signal for the first gain stage of the section. Low settings are smoother and higher settings are more aggressive (details in the Favorite Settings section).

Drive Control – Sets the amount of distortion by controlling the level between the 2 gain stages of the section. Pull this control to shift into more gain and girth for the distortion.

Level Control – Sets the output volume of the section. Higher settings are “bigger” and more 3 dimensional. Newer versions may have a pull to engage a HI CUT feature.

MASTER SECTION

Reverb Control - Sets the amount of reverberation effect, takes the reverb out of circuit when rotated to zero (there will be a slight volume and tone change).

Presence Control – The presence circuit uses global negative feedback to remove low frequencies which frees up bandwidth for more midrange and highs. Think of it as a tone control to balance the relationship between highs and lows, especially when the amplifier is naturally producing increased low end at louder volumes. The control clicks off when rotated to zero for no presence.

Master Volume – This is an active control and actually adds gain at the higher settings. The cleanest tones are achieved at settings below 7. New versions may have a “PULL LO MASTER”

REAR PANEL

50 WATT / 40 WATT Switch – This switch changes the bias architecture of the output tubes from fixed bias (50 WATT) to cathode biased (40 WATT).

The 40 WATT position allows the use of 6V6 tubes for lower power output (~18 Watts with 6V6). 

PENTODE/TRIODE Switch

SEND and RETURN Jacks – The send jack connects to the input of an external effects device and the return jack connects to the output of an external effects device. The return jack interrupts the signal path so the external effects unit must mix the wet and dry signals.

Footswitch Jack - This is a standard 180 degree 5 pin DIN jack for footswitch connection. The pinout is conveniently located on the rear panel for use with automated switcher conversion boxes.

SMOOTH Switch – Employs local negative feedback in the clean preamp for a hint of compression.

Humbucker / Single coil Switch – Sets the amount of bass gain in the input stage, useful for matching the amplifier to the guitar type.

Three button footswitch 

TWEED – Midrange Boost feature. When engaged the size of the treble capacitor is increased to allow for more upper midrange, at the same time it does a lift of the midrange control for maximum midrange. The effect can be lessened by pulling the front panel Volume control which eliminates the midrange control lift. The footswitch button does not work when position 6 of the rotary MODE switch on the front panel is selected because it is a duplicate function.

DRIVE – Character Boost feature. When lit, the Drive section of the amplifier is active, not lit, means the section is bypassed. The footswitch button does not work when the front panel Gain control is rotated to zero because it is a duplicate function.

BOOST – Girth Boost feature. When lit, adds volume and tone by doing a partial tone stack lift. The footswitch button does not work when the front panel Bass control is rotated to zero because it is a duplicate function.
