The Pusher had been LunaStone’s sole clean boost pedal for some time and demand for a refresh became strong. 

After responding to requests from various users, the company upped the amount of boost from 15dB to 18dB, as hinted at in the name of this new replacement. Same as The Pusher, the Boost 18 is a 9V-adapter-powered mini-sized booster with offset connections and a single chicken-head knob to dial in the amount of boost. 

The JFET circuitry here is designed to add tonal enrichment as well as boost, so even with no boost added, we found a welcome lift in clarity. The extra 3dB of boost might not seem much but it provides more leeway for some applications. Full on it certainly drives our clean amp into edgy raunch, while lower boost settings give us naturally voiced ‘extra channels’ for driven amps and dirt pedals.
