Double D Overdrive /DD-1

User Guide

Operation of the DD-1

Operation is fairly straightforward. There are two inputs on the side of the unit: a 1/4″ input jack on the right and a 1/4″ output
jack on the left with a batteryswitch on the input jack.


There are six controls on the unit two sets of three for each over drive Drive Tone and Volume, a mode switch to switch between Lose or tight plus a foot switch to bypass the effect, and an LED to indicate effect operation. On the side there is a trim pot to set the overall gain of the unit.

Drive: Increases the gain of the Overdrive circuit which increases the distortion and sustain of the unit.

Tone:a high cut filter use it to make your sound warmer and fatter.

Volume: This control sets the overall output of the unit. Use this for level matching between the effected and unaffected signal.

Power Supply: 9 volts DC. Either internal using a 9 volt Battery.To access, remove the four screws on the sides of the unit and pull apart. Note! Battery must have at least 7 volts for unit to work!
Or external using a mini plug, Tip positive. External supplies should be 9volt DC regulated.(50 milliamp or more),


Tight-Lose Switch: This switches between silicon Diodes and Germanium diodes for the distortion generating devices. LED’s have a tight sound and are a bit louder. Germanium diodes have a looser
more classic fuzz sound with less output volume.

TRIM POT. Sets the gain of the Driveulator output amplifier. It is useful to turn it up if you are using the Germanium diodes (lose) as your primary distortion setting. Or you can turn it down if the unit is too hot for your system.
