Bass 

– Adjusts the amount of bass applied to the effected signal. If you are 

using an “S style” single coil guitar rather than a humbucker loaded 

instrument, you may find you need more bass to “fatten” up the tone. 

When in the fully counterclockwise position, the tone will be much 

thinner and brighter and when fully clockwise it will be fuller, darker and 

heavier around the low end. 

Treble 

– Works in the same way as the bass knob but controls the amount 

of treble on the effected signal. Again, fully counterclockwise the treble is 

reduced considerably and clockwise brings it forward. You may have to 

tweak both the treble and bass controls simultaneously to find 

your 

sweet 

spot.

Top Cut 

– Just like the original amplifiers that inspired this pedal, the top 

boost can be used to tame some of the high end; by definition this pedal 

is very bright. With that said, if you have a bright sounding amp/guitar you 

may need to adjust accordingly to compensate for some of the high 

tones. When the knob is fully counterclockwise the entire range of highs is 

allowed through. As you turn the knob clockwise the highs are cut more. 

Gain 

– Increases the amount of overdrive produced by the pedal. When 

fully counterclockwise there is no additional gain applied. As the gain 

knob is turned clockwise, the amount of gain correspondingly increases. 

This control works very closely with the “headroom” switch. You will notice 

more of a pronounced midrange hump as the gain is increased. This effect 

is extremely accurate to the sound of how the original amps reacted/ 

sounded when being driven! 

Volume 

- Adjusts the output volume of the effected signal. Fully counter- 

clockwise is “off ” and clockwise is considered to be “wide open”!

Boost Level

 - Adjusts the amount of volume that is applied before the 

main gain circuits. Like the volume control, counterclockwise is “off ” and 

clockwise is “full”. When the main pedal is not activated, this will act as an 

independent Class-A booster. 

Headroom 

- Gain stage control. When in the “30” position, there is more 

headroom and the pedal takes longer across the gain control sweep to 

reach a saturated overdrive. This gives you a broader range of clean and 

lightly overdriven tones. When in the “15” position, the headroom is much 

lower and the overdrive arrives much quicker; this gives you the greater 

option of overdriven tones. Just keep in mind that the gain knob should 

be used in conjunction with this control!

Power Requirements

The pedal can be powered by a 9V battery. The battery terminal is located inside the pedal. If 

using a power supply, power needed for the pedal is 9V DC, regulated, center pin negative, as 

supplied by most standard Boss™/Ibanez™/Etc. supplies. The pedal can be safely powered with a 

multi-supply, like the Visual Sound 1SPOT™. The pedal was designed explicitly around the usage 

of a 9V DC power source, and is intended to sound its best at 9V. To avoid damage to the pedal, 

do not exceed 9V DC, do not use center pin positive adapters, and do not use AC power. Using an 

incorrect power adapter can lead to damage and will void the warranty on the pedal. This pedal 

draws 

13mA

.

Please note

: If you are using a battery, it 

will 

drain when the input cord is plugged in.
