Blue-Power Switch & LED

The blue-Power LED will illuminate when the unit is turned on.

Preamp Select Switch

Depending on your preference, choose either solid-state or tube gain input for the preamp.

Passive 0dB & Active -6dB Input Jacks

Use the Passive Input (0 dB) for bass guitars that have passive electronics (such as single-coil, split-
coil and Humbucking pickups). Use the Active Input (-6dB) for hot, or active pickups. These inputs

are not intended for connecting more than one instrument at a time.

Tip: Using the -6dB input when playing your bass (passive or active) at full gain, and you pluck the
strings hard will reduce the potential of input clipping.

Gain Control

The Gain control is a volume adjustment for the preamp, which is selectable between using solid­state or tube circuitry. The tube circuitry features a single 12AX7A, dual-triode preamp tube. The Gain

control should normally be set around the middle, which should be the position for most basses. If
your bass has an unusually low output, increase the Gain control to the desired level, conversely for
higher output basses use a lower setting. Increasing the Gain control also affects the level of drive
when the Tube-Drive feature is engaged.

Compressor

To increase the consistency of your tone and further the performance of the power amplifier, we have
provided an adjustable compressor. This compressor is fairly simple to use, with only a simple thresh-
old control to make adjustments. The compression ratio is 2:1 and the attack / release-time is preset

for optimally.

Tip: To use the Compressor, rotate the control clockwise until the desired threshold is reached. It will
be apparent to you audibly as well as visually; a red LED (located to the right of the control) will illu­minate as the compressor limits the signal. The LED will also indicate the how much compression is

being applied by its intensity and duration.

TUBE

Drive Control

TUBE

The

Drive feature controls the amount of tube-overdrive, or saturation, in the signal. The tube-

overdrive is powered by a 12AX7A, dual-triode preamp tube. Activate the circuit by depressing the

TUBE

Drive mode switch or using the optional footswitch. The green LED, above the

will illuminate indicating

TUBE

Drive mode is active. To achieve higher levels of overdrive, increase the

little into the extreme of MAX, listen to the gain level take off. Naturally, there will be some extra noise
coming out of the amplifier at this high setting. This is normal, and a perfectly acceptable tradeoff,

when achieving so much overdrive.

Tip: Many unique sounds can be obtained by changing some controls in conjunction with

TUBE

the

Drive control. Some bassists prefer minimal distortion with a lot of Scoop, some
may prefer massive overdrive (and lots of midrange growl) and others may go for that deep
dry bass. These sounds can be achieved easily by adjusting the Scoop, the Tube-Drive and

the Tube-Drive’s Mix controls in conjunction with each other.

The

Drive switch is located on the front panel and is used to activate the

circuit. The circuit can also be activated by an optional footswitch (AFS-2). A green LED, located
directly above the

Drive Mix Control

The Drive Mix control becomes active when the
underlying clean tone below the overdriven tone. In the Dry, counter-clockwise setting, clean signal
is allowed to dominate the mix, with no overdrive. When rotated clockwise, into the Wet region, the
overdriven sound becomes more apparent. The
is the dominant sound in the mix (fully Wet position). This helps you achieve a perfect Wet/Dry blend,
between a completely clean and a completely saturated overdrive tone. This is a unique and handy

feature that allows unheard of levels of tonal control.

Tone Controls

The five overlapping controls cover the entire audio spectrum. Each tone control permits a wide range
of sonic adjustment. Each tone control has a variable boost and/or cut of 15 db. The center position

denotes a neutral or nominal setting.

Tip: It’s a good idea, when starting out, to center all tone controls. While playing, adjust them until
you achieve the desired sound. Remember, if the Parametric Mid control is set at 0, rotating the
Frequency control will have no effect. The Bass control adjusts the level of the lowest note frequen­cies, Low-Mid the next range up from that. The Parametric Mid allows more precise control for the
mid frequencies - more on this below). The Hi-Mid covers the highest notes and middle harmonics

and the Treble regulates the upper harmonic range.

Parametric Mid Control

The Parametric Mid control enables adjustments to be centered on frequencies ranging from
150 Hz – 15 kHz.

Tip: To use this control, set the position of the Parametric Mid level control to cut or boost. Rotate the
Frequency control until the desired frequency range is found. Once the frequency range is chosen,

adjust the Parametric Mid level until the desired cut or boost level is achieved.

Tip: Using the Parametric Mid in conjunction with the Scoop feature. When using the Parametric
Mid, it’s possible to enhance the Scoop’s capabilities by letting the two tone-shaping controls work
in tandem. If you like the added bottom of the Scoop but wish to soften the midrange at 1Kz (but still
maintain the higher frequencies); adjust the Parametric Mid Frequency control to 1.0Kz and then use
the Parametric Mid level control to cut as much as you need. The 400 Hz frequency has been conve-

niently marked on the Parametric Mid’s Frequency control.

Scoop Control

The Scoop enhances the tone of the bass by shaping the mid frequencies around 400 Hz. By shap­ing the bottom-end fundamentals, and high frequency brilliance, subtleties normally hidden are
revealed. The Scoop shapes specific upper and lower frequencies while notching particular mid
frequencies. It utilizes a variable tone curve that reacts differently depending on where it is set. The
result is a greatly expanded tonal range and control over that tone. Its fundamental use is like the
traditional Scoop control found on our other popular Yorkville Bassmaster amplifiers, but with greatly
expanded dimension and tonal control. As shown on the front panel, the center frequency of the
scoop is centered around 400 Hz. If you desire more scoop, turn the parametric mid frequency con-

trol to 400 and the gain counter-clockwise until the desired amount is reached

Tip: As with the tone controls, it’s recommended to set the Scoop control initially at the mid point.
Adjust it slowly, either way, until the desired tone is achieved.

Tip: Combine the Scoop, the

TUBE

Drive and the Drive Mix to their maximums and play your bass while slowly rotating the Scoop

from its off position to its MAX position, you’ll find the variation in the effect to be quite dramatic and
yet very musical at the same time.
