SoloDallas Schaffer Replica TSR4 Classic Boost Pedal

Angus Young's Legendary Boost Unit in Stompbox Form!

Written by

Sam Beattie

SoloDallas mastermind Fil Olivieri built the company on creating an authentic recreation of the legendary Schaffer Vega Diversity Wireless System. These units were prototyped in the mid '70s, and were not only hailed as one of the first and most effective wireless guitar solutions, but also lauded for the sound they produced.

Despite the fact that this equipment was originally intended as a wireless system for performers, the tone they produced was the reason they ultimately became the stuff of legend. When Schaffer ceased production of the SVDS, its incredible tone slipped into obscurity - and that's where Solo Dallas come in!

Fil Olivieri was an avid AC/DC fan who spent much of his time seeking out the iconic sound that put the Young Brothers on the map. When he discovered that they used SVDS units both live and in the studio as part of their earth-shattering rigs, he set about finding one and recreating it; the result was the Schaffer Replica, which proved to be a huge hit among guitar aficionados, and set Solo Dallas on the path to success!

Solodallas Schaffer pedals - Angus Young's secret ingredient!

The TSR4 Classic

The TSR4 takes Olivieri's Schaffer Replica formula and crams it into a stompbox enclosure. With two simple controls (input/power and output/boost), there's really not much to it; simply plug this thing into your chain and breathe new life into your tone! 

With a 100% analog compression circuit and unparalleled construction, the TSR4 delivers everything you'd want from a boost pedal. Whether you intend to use it to boost certain parts of your playing, or have it as an 'always-on' addition to your rig, you'll be amazed at what this unit does! Expect heaps of warmth, rich sustain, excellent harmonic detail and a pronounced mid-range 'honk' - make your sound stand out from the crowd with the TSR4!
