From the vendor
The Samurai Boost is our take on the Keeley Katana Boost Clone A super small part clean boost with a toggle to add a little grit – the boost offers around 30db volume increase! The original used a push/pull switch but we’ve moved this to a toggle for ease for the diyer and it even fits in a 1590A/Gorva M45 if you’re feeling it! With an onboard voltage doubler upping the voltage to 18V internally but powered by a standard 9V negative center psu, giving you more clean headroom before any breakup – remember to use components rated to 25V minimum. Controls:
• Volume
• Boost (Toggle DPDT – ON/ON)
Note: Remember to socket any IC’s and transistors! Compares to: Keeley Katana Boost Clone
