Mad Professor / Stone Grey Distortion / 2010's / Grey / Effect For Sale
|
BJF design distortion pedal for guitar
The new Mad Professor - Stone Grey Distortion (SGD) is a modern high-gain distortion pedal with unparallelled clarity and definition.
This pedal was developed for high gain applications and specifically for clarity at heavy distortion levels.
The Stone Grey Distortion is unique in that it has razor sharp dynamics and high gain intensity. It's ready for drop tuning, 7 string, and modern rock players who are seeking extreme gain with intense "string to string definition".
Play a chord and hear each note distinctly, instead of it turning to "mush" like many other high gain pedals.
With the gain turned down, the Stone Grey Distortion approaches overdrive-like textures and responds to the player's touch and dynamics like our other Mad Professor pedals do.
Build the Mad Professor way: small footprint and big tone.

Mad Professor Amplification Ltd, Marketing and management
Harri Koski: Guitarist, marketing, cordinating the production, helping hand.
Harri has been playing guitar since mid 70´s and his serious hobby turned into a business when he started Custom-Sounds (www.custom-sounds.com) in 1996. Custom-Sounds was a high-end guitar gear company from the beginning and it was one of the first “boutique" guitar shops on internet. His co-operation with Bjorn Juhl started the BJF pedals business and soon these two soul brothers were talking about the ultimate amplifier. Bjorn Juhl and Harri had the mad idea about designing the ultimate guitar tube amplifier and to make it right here in Scandinavia. Bjorn put on his propel-hat and Harri put all his energy and money into this project. Soon we found the right people to work with us and the world got a brand new amplifier that was not a clone of any vintage amp as these modern hand-wired amps often are. Harri has a collection of various Gibson guitars and early JV Squier Fenders and plugs these into his serial no: 000 Mad Professor prototype head that is played loud almost every day.
