The Caffeine Boost (Classic JFET) is a powerfully versatile boost pedal in an ultra-compact form factor that can fit on even the most crowded pedal board. Inside is a discrete circuit that uses the increasingly rare J201 JFET transitor to achieve a tightly controlled and tuned amplified signal. It can be used at low settings as a volume leveller for your long signal chains, a powerful signal boost for guitar solos that stand out above the mix, or at maximum boost level to push your amplifier for a wonderfully transparent and natural overdrive sound.
