Yesterday I picked up a custom pedal from cog effects. It's a 2 channel blender. Every channel has a phase switch clean volume knob loop volume knob Low Pass Filter for the clean signal when channel is engaged Bass & Treble control for the loop signal I use it two clean blend 2 dirt boxes, a big green muff and a rat clone. The lowpass filter on the clean signal is genious. It enables really a smooth blending of the clean and loop (dirt) signal. After using a Boss LS-2 for almost 7 years, i realized how crucial a phase switch is, that was the main problem before with the muff that sounded just thin with the LS-2. Again awesome work by cog effects. The pedal is supersturdy and i love the brushed alluminium look. full board:
