Congratulations you are investigating the very toneful Java Boost! The most musical and rewarding boost pedals ever built. Handcrafted with the finest current manufacture components and a secret stash of NOS Mullard OC44 transistors (the very ones used in the original pedals), this pedal offers the same incredible response and sound quality of the heralded late sixties treble boosters, with new ways to control the range of output frequencies and boost gain.   Use this pedal in front of a tube amp or to drive one of our TS9 MOD PLUS or BD-2 Phat Mod pedals!
