Use the BASS and TREBLE controls to dial in the basic tone. Note that the TREBLE control is situated
before
the tube stage in the signal chain, yielding smoother harmonic overtones. If the CLIP LED illuminates when
you dial in higher TREBLE settings, simply adjust the GAIN control to a lower level.
4.2 THE VARIMETRIC EQs
Handle the VARIMETRIC EQ sections as you would a semi-parametric EQ. The difference lies in the
VARIMETRIC EQ's auto-variable bandwidth and slope, which enables you to achieve substantially more
musical results. The easiest way to use it (and the best way to acquaint yourself with how it works) is to do
the following:
- Turn the LEVEL control all the way up so you can really hear the results when you tune a frequency range
in the lower midrange.
- Dial in the desired low-mids center frequency via the FREQ HZ control. (You will hear a wah-wah effect
when turning this knob. If you stop rotating the pot at any point you will hear that particular frequency
especially pronounced. You may find a given frequency particularly annoying, but not to worry, help is near:
simply attenuate the culprit.
- You can now use the LEVEL control to amplify/attenuate selected frequencies as desired.
- Use the same procedure to tune the upper-mid frequencies via the FREQ KHZ and LEVEL controls (LEVEL
to maximum, tune FREQ KHZ, then adjust LEVEL to amplify/attenuate the chosen frequencies).
- Hit the EQ ON button if you need to compare your EQed tone to the basic tone.
- If you leave the LEVEL control in the 12 o'clock position for a given frequency, that frequency will not be
affected.
With a bit of practice, you can also tune an attenuated frequency range (rather than artificially
overemphasizing it first like we just did), but keep in mind that for the human ear, attenuated frequencies are
generally more difficult to discern.
Why call it "VARIMETRIC" rather than "PARAMETRIC?"
