An early version of the now infamous Katana Boost!

Anyone that has spent any amount of time digging into the gear of John Mayer has no doubt heard about the Katana Boost. The quintessential clean boost, the Katana take your volume and gives you a good amount of clean push without altering too much of the source tone. A handwritten date in marker on the baseplate indicates 2006 as the year of production, making this a super early example of this iconic boost. 

Cosmetic condition is reasonable with wear present to the enclosure and graphics. Hardware and electronics are fully functional. No box included.
