Seeking chime, articulation and buttery-smooth presence? Foxy’s a one-stop-shop! With airy highs, impeccable breakup and sublime mid-range bite when pushing the gain, Foxy is primed to take on everything from sultry Jazz to rauch-fuelled Rock n’ Roll.

Want gain? NiftyFifty’s got it on tap! It’s aggression incarnate. It’s punchy. It’s super-versatile covering everything from a warm full-throttle onslaught to a searing lead tone that cuts through any mix.

Tight response? Check. Rich in harmonics? Check. Searing, perfectly balanced gain fused with lashings of sustain? Oh Yes! This pre really is a “triple threat” for the guitarist venturing into hard-rock and metal territory.
