From the vendor

Project overview

The TV Channel is based around a classic hard-clipping overdrive, the DOD 250/Distortion +; the people from EQD took the base of this classic drive and took it one step further adding, making it double, and adding 3 clipping options per channel.

Introduction

This circuit has been developed by the people from Earthquaker inspired on one of the most classic and iconic overdrives, the DOD 250/Distortion+.

The concept of the TV Channel is simple yet effective. It consists of two DOD250 circuits placed on the same board, each with 3 different clipping options and a toggle to select which one to activate.

On Channel “ONE,” you can choose between the “Silicon” mode will be bright/loud/fuzzy and has a natural tube type break up. “Germanium” mode is a little looser with more lows and warmth and less output.

On Channel “TWO” LED mode is the loudest, cleanest, and most touch sensitive/least compressed. “Mosfet” mode is the most compressed with a tighter crunch, the group’s biggest hesher.

Controls

Green Controls

• Gain: Adjusts the drive, dirtier clockwise, cleaner counterclockwise

• Green: Sets the output level when the green LED is lit.

• Toggle: Silicon clipping, No clipping, Germanium Clipping

• Red Controls

• Gain: Adjusts the drive, dirtier clockwise, cleaner counterclockwise

• Red: Sets the output level when the red LED is lit.

• Toggle: LED clipping, “No clipping, Mosfet Clipping

Foot-switches

• Channel Switch: Selects between Red and Green channels

• Activate Switch: Turns the effect on and off.
