6. Tone Controls
Each tone control permits a wide range of adjustment. The five overlapping controls cover the
entire audio spectrum. The Bass adjusts the level of the low frequency range, Low Mid the next
range up, Hi Mid covers higher notes and middle harmonics and the Treble control regulates
the upper harmonic range. Each tone control has a variable boost and/or cut of 15 db. The
center position denotes a neutral or nominal setting. The Parametric Mid control is described in
detail in section 7, below.
User 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.
7. Parametric Mid Control
The Parametric Mid control enables adjustments to be centered on frequencies
ranging from 150 Hz – 15 kHz.
User 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.
User Tip: Try 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 conveniently marked on the Parametric Mid’s Frequency control.
8. 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. 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 control to 400 Hz and set the gain counter-
clockwise to cut until the desired amount is reached.
User 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 Drive Mix for unparalleled levels of tonal control.
Set 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.
9. Effects Return Blend Control
Use the Effects Send jack to send a dry, uneffected signal to an external effects unit. The externally
processed signal then can return to the amplifier through the Effects Rtn jack. The Effects Rtn blend
control regulates how much of the wet (effected signal) is blended with the dry signal (un-effected
signal). This can range from totally dry (without effects) to mostly wet (effects applied).
User Tip: If a wetter signal is desired, set the output signal from the external effects
processor to a high output.
10. Bass Resonance Control
The Bass Resonance control adjusts the amount of low frequency damping of the amplifier.
Turning the control clockwise towards Loose reduces the damping factor and allows the
resonance of the speaker cabinet to be more pronounced. Setting the control towards Tight
increases the damping factor to achieve a punchier sound.
