The Obsessive Compulsive Drive is capable of producing the complex array of overtones, and tube-amp like tone, it has a lot of of available gain (about 30db). The gain is very uncompressed.

the HP/LP switch allows you to get more "British" like sound or very close accuracy to the original sound with very little coloration that better suites for clean boosting.

The pedal can be run on the 9 volt standard guitar pedal adapter, or any 9 to 18 volts regulated DC adapter with the negative center pin. Using more voltage should bring louder and more dynamic sound.
