Created as a faithful 1:1 replica of the original Schaffer-Vega Diversity System (SVDS) audio circuitry, The Schaffer Replica has a truly unique sound signature. This device brings back the elusive sound heard on albums such as AC/DC's Back in Black, Highway to Hell, Powerage, For Those About To Rock and many others from bands of the era. The artist list from the '70s is staggering: Aerosmith to ZZ Top, ELO to EWF, Grateful Dead to Rick Derringer. And yes- David Gilmour and Angus Young, two of the most devout users who both continued to use the units well into the following decades after production ceased.
The circuit is 100% analog and features an analog limiter derived from a previously unseen and very musical Opto-Isolator (a vintage optical limiter) recently discovered in our latest reverse-engineering of the original Schaffer-Vega Diversity System TX10 Transmitter, and a compander (compressor-expander), giving your tone extra sustain, touch sensitivity, fatness and a rich harmonic content.
The EX Tower version is built with high quality through-hole components and housed in an enclosure identical to the original '63EX' receiver, which was 3D-scanned and faithfully from a single metal block, patiently incorporating 2017 machining technolgy
The latest iteration features several enhancements our artists have requested over the past 18 months, including two dramatic enhancements:
1.A toggle (DPDT) switch on the back panel enables or disables the opto-isolator (OI) for even more tonal flexibility. This allows the operator to incorporate the optical compression for certain projects, and then instantaneously eliminate the OI whenever necessary.
2. An additional extra normal/boost mode toggle switch allows for either a smoother, quieter operation with a lower noise floor, or the "monitor mode" which was discovered by David Gilmour and Angus Young in the 70s, creating history: a full out 30db of clean boost to "give a guitar hell" (in Angus Young's own words, Guitar Player Magazine, March 1984).
The SoloDallas EX Tower reproduces not only the sound, but the complete tactile and aural experience of operating a long-lost vintage piece of analog audio gear: a time-tested, refined piece that will immensely enhance your musical experience for decades to come.
NOTE: This is NOT a wireless unit.
