From protones website: After 4 years of amazing transformation and variations, the Misha Mansoor signature line of pedals from Pro Tone Pedals is coming to an end. Dennis and his team will lovingly complete handcrafting the final few dozen units before saying goodbye forever. The Mansoor line of overdrive pedals (Attack, Deluxe, and Variable Attack) has been the foundation of the modern progressive metal tone and has been loved by legends and future legends alike. Users of the Bulb line include Volumes, The Acacia Strain, Brendon Small, Memphis May Fire, Living Colour, and countless more. When it went into production in 2012, the Bulb Overdrive solidified Mishas position as the modern leader in progressive metal tone. Crafted to fit his demanding needs, the Pro Tone Pedals Bulb Overdrive has continued to evolve over the years to move as Mishas needs progressed. Be very clear, Pro Tone Pedals is retiring these signatures models forever. Limited quantities are available directly through ProTonePedals.com. There will be no retirement sale. These are the last of their kind. Dont wait. If you are short of cash we would highly recommend you reserve yours by using our payment plan option While Misha goes back to the experimentation that has always set him apart from his peers, Pro Tone Pedals will continue our own sonic experimenting to expand the art of guitar effects pedals.
