LOW Knob -The LOW knob is a volume control for the low or bass frequencies.

> Which frequencies specifically?

The further you turn the LOW knob clockwise, the louder the low frequencies will be.

> How much louder? 12db?

The LOW knob controls the output volume from the Knockout’s 7-Pole Low-Pass Filter.

> I know what a Low-Pass filter is. But what is a 7-pole LPF? How does it behave?

The low pass filter has a fixed cutoff frequency of 85 Hz.

> ??? – Does this mean freqs below 85 are unaffected (the same freq as a low E string)

The LOW knob is responsible for contouring the bottom end in relation to the total sound.

> That could mean anything. What kind of contour. A mid-scoop. A bass roll off? A simple boost?…

DRY Knob – The DRY knob is a volume control for the signal present at the Input Jack.

However, if you turn the knob to its max position, it is does not give you your uneffected input signal.

The output volume of the dry signal will increase as this knob is rotated clockwise. Use the DRY knob in conjunction with the LOW and HIGH knobs to create your tone.

HIGH Knob – The HIGH Knob is a volume control for the high or treble frequencies. The further you turn the HIGH knob clockwise, the louder the treble frequencies will be. The HIGH knob controls the output volume from the Knockout’s 6-Pole High-Pass Filter. The high pass filter has a fixed cutoff frequency of 6.5kHz. The HIGH knob is responsible for contouring the high end to the total sound.[/quote]

> The same questions apply as those for the Low knob.

I read the manual, but it doesn’t really elucidate the function of the controls. I do like the sound of the pedal. It imparts a nice sparkle. But I’m afraid that I may be trying to use it for something it is not – a plain old EQ pedal. Like I said, I’d like to figure out how to retain the unaffected to of my tele, using the Knockout to add a little air for that glassy fender tone.
