Gain

: This control adjusts the total amount of gain that is 

applied to the signal path. Turning the Gain control 

clockwise will increase the amount of gain in the circuit. 

Whether you use a little gain for a smooth break up - or 

crank your gain all the way up for great thick, vintage style 

overdriven tone - your drive will stay true and not fizzle 

out as much as the original Screamer style of pedals.

Smooth/ Lift Switch

: The Clarksdale features a small 

toggle switch that is labeled LIFT and SMOOTH. The Lift/ 

Smooth switch will allow a player to either sit in the mix 

with the Smooth setting or allow your leads to standout 

with the Lift option.

Bass: 

Adjusts the amount of bass applied to the effected 

signal. If you are using a Stratocaster® 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. 

Mids: 

Adjusts the total amount of midrange that is applied 

to the effected signal. Unlike a traditional Screamer style 

circuit that had an ever present midrange bump – you can 

now choose to dial in less or even more mid-range as you 

see fit.  

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 consid-

erably and clockwise brings it forward. You may have to 

tweak both the treble and bass controls simultaneously to 

find your sweet spot. 

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 17mA.

Please note

: If you are using a battery, it will drain when the input cord is plugged in.
