For clean tones use the clean PREAMP and adjust the bass and treble for the desired
tone and then adjust the mid and mid-sweep settings. For a more forward sound try
boosting the midrange above 12:00 and sweeping the mid between 10:00 and 2:00. For
a more scooped or hollow tone pull the midrange back below 12:00 and adjust the sweep
for the preferred frequency. When cutting the mids it may be desirable to add additional
treble boost.
For Distort tones start with just the DISTORT circuit active (PREAMP off) bring up GAIN1
or GAIN2 and bring the midrange boost a bit forward with the sweep between 9:00 and
3:00. This will provide a more classic rock tone. By pulling the midrange control back
between 8:00 and 12:00 you will get a more scooped midrange response. Sweep the
midrange frequency with the MID control in cut between 8:00 and 11:00 to find the
desired mid scoop and then add BASS and TREBLE to suit.
PREAMP OVERDRIVING THE DISTORT FOR MASSIVE GAIN
For incredible GAIN and that over the top metal Distortion use the clean PREAMP to
overdrive the DISTORT section. The settings shown are a good starting point to find your
desired settings.
In this example select GAIN2, PREAMP ON and DISTORT ON. Adjust the Decimator to
remove the gain noise but still allow fluid operation of the noise reduction. The Decimator
threshold will be slightly different for various guitars based on the type of pickups used.
