The very stylish, top-end Class A boost from Korean maker Geo Woo looks like it was designed by a tattoo artist turned silversmith; a peek inside reveals even more craftsmanship: clean point-to-point wiring and good quality components.

Instead of Gain or Volume controls, the Moollon offers only a three-stage transistor- based EQ (Lo, Mid, Hi) and an On/Off switch with LED indicator for straightforward tone-shaping simplicity. Many newer boosts based on the vintage units such as the Rangemaster offer a switching option for mid or bass boost. The Moollon’s three independent EQ controls, by contrast, each drive a select part of the frequency range. This makes it extremely versatile, since it’s essentially several different types of boost in one, but it allows you to blend the different types together to find just the right boosted tone.

With the Hi control on full by itself, the pedal sounds most like the vintage treble boosters that inspired it, putting a cutting edge on the tone and adding sparkle. The Mid boost fattens up my Strat’s single coils comfortably, without pushing the amp too hard or losing the clarity and bounce. The Lo control serves up a smooth, warm, slightly fuzzy boost that worked well with the neck P-90 on a Gibson LP BFG.

The Class A boost satisfies as both a clean boost and as a way to kick an already overdriven amp into a tasy harmonic crunch. Like a good boost should, the Moollon turns the guitar’s volume knob into something more like a gain control: rolling off cleans up the excess grit, while rolling it up increases sensitivity and responsiveness. Although it’s not vintage spec, it does deliver a particularly good “old school” tone—raw and energetic— with great harmonic content, sustain and definition. – CB
