The tone inside your head

The Mutt is a 2-in-1 distortion pedal. It is meant to be plugged into the front end of a clean amplifier.

You can certainly try that, but that is not the manner in which the pedal was designed for. 

You can certainly try that, but that is even MORE not the manner in which the pedal was designed for.

No. The pedal was designed after a very specific effect of blending these two amps at the same time. If you want to only hear the Martian side, turn the Blend knob fully toward the left. If you want to only hear the Erectifier side, turn the Blend knob fully toward the right.

If you want a clean tone, just turn the pedal off :)

Unfortunately that wouldn't work. Because the Blend knob is determining how much of each amp is in the circuit, if you were to suddenly bypass one, the remaining amp would only be as loud as it is blended.

For example lets say you're running a blend of 75% Erectifier and 25% Martian. If you were to bypass the Erectifier, you would only be left with 25% signal strength passing through the pedal which would be drastically quieter than anything you want to use. 

The Mutt runs on 9V DC Negative Center power and consumes 24mA. 

Because of the high-gain nature of the pedal, I'd strongly encourage a power supply with isolated outputs rather than daisy chaining pedals together, to help prevent unwanted noise from being amplified.

No The Mutt does not include a power supply. It only consumes 24mA of power and should be powered by most simple 9 volt guitar pedal power supplies. Furthermore I have a wide variety of international customers and including a power supply that doesn't work in your country seems rather wasteful. 

The Martian is based on a Plexi/JTM 45 style British amp.

The Triple Erectifier is...well...you can probably figure that one out.

I opted for the cleaner end of the British amp spectrum for two reasons:

1) We know that Tom used the clean channel of the JCM 900 with the gain turned up for a crunchy articulate tone to blend in, rather than the 900's lead channel.

2) I felt that this would make for a much more versatile pedal that can go from clean to crunch to distortion, rather than just two flavors of distorted amps. 

The Voice switch allows you to toggle between a lower gain, warmer distortion, and a higher gain, brighter distortion. Think of up as Modern and down as Vintage.

This is especially useful depending on what type of amp you're plugging in to, or the character of your guitars pickups.

Yup!

No. The Mutt is 100% all analog circuitry. 

Each Mutt is hand assembled in my shitty apartment, in Los Angeles, CA.
