Vs Audio Jangle Master OD

A Tribute to the Vox AC-30 TB and Legendary Sixties Boosts

Inspired by the spirit of the highly sought-after 1964 AC-30 TB "Treble and Bass Boost," the VS Audio JangleMaster aims to capture that unique blend of brightness, projection, and dynamics that defined the early great rock tones. This sonic aesthetic is associated with iconic guitarists and bands such as The Edge, Richie Blackmore, Jeff Beck, Tom Petty, Keith Richards, Pete Townshend, and The Beatles.

The pedal also draws from the tradition of the treble booster pushed into an AC-30, a combination made famous by players with incisive touch like Rory Gallagher and Brian May. The goal is not just to add highs: it's to sculpt the attack, tighten the lows, and make the guitar sing in the mix with that very "early rock" bite.

Who It's For, Which Styles, and Where to Place It on the Pedalboard

The JangleMaster is aimed at guitarists seeking an overdrive/preamp pedal capable of shifting from a sparkling clean boost to a thicker saturation, while maintaining an amp-like feel. It's ideal for classic rock, blues rock, britpop, indie, jangle pop, and more broadly whenever you want chords that shimmer and leads that stand out.

On a pedalboard, you can use it early in the chain as a characterful booster (to wake up single-coils or add bite to humbuckers), or later in the chain to exploit its true preamp side. It works very well both in the studio and live, especially if you like to control your gain with your guitar's volume and your playing dynamics.

Controls, Modes, and Design: Built Like an Amp Under Your Foot

The JangleMaster offers an "amp-style" approach: the Gain control drives the typical overdrive, from a snappy clean tone to a more sustained saturation. The independent Boost switch lets you toggle between a Rangemaster-style treble booster mode (perfect for thickening the upper spectrum, adding bite, and making solos stand out) and a more traditional volume boost to push another gain stage or an amp.

The Bass and Treble knobs are highly interactive, like an amp's tone stack: you can tighten the lows for more precision or round them out to thicken rhythms. The Cut control acts as a high cut placed after the Long Tailed Pair stage, allowing you to adjust brightness, potential harshness, and dynamic feel, even when playing through a speaker simulator or recording interface.

The construction emphasizes reliability and tone: TRIAD Magnetics Military "Red Spec" audio transformer, compact brushed stainless steel enclosure, top-mounted jacks for optimized space, true bypass, and silent relay switching for stage use without "pop" noises.

Sound Signature

The VS Audio JangleMaster's signature is that blend of chime and cut in the upper mids: shimmering chords, percussive attack, and an "instant" feel under the fingers. The lows remain precise and rounded, helping keep rhythms clear even as gain increases, while the high end retains air without becoming harsh thanks to the Cut control.

In treble booster mode, the pedal emphasizes bite and highlights the character of the pickups and right hand: perfect for singing leads, sharp riffs, and "vintage rock" tones that need to cut through a band. Used later in the chain, it can act as a preamp and deliver that pushed Vox amp impression, both in bright clean tones and snappy crunch.
