Red Devil

Classic American sound taken to the next level.

The Red Devil is a dual stage tube preamplifier designed with coloration and low end in mind. Essentially a tube A312 preamplifier, it retains the aggressive character of the original while adding further harmonic distortion, low end and coloration with the addition of a second output stage based on a ECC83 tube and a US-made 5:1 steel output transformer. 

The Red Devil is built with premium components

The US-made 1:8 input transformer and our very own reverse engineered SA-25 discrete op-amp are exact replicas of those found in an vintage API 312 card from the 70’s and have been carefully auditioned to impart the same character and punch that these units are famous for. The op-amp is followed by a ECC83 tube that adds further coloration and mojo to the circuit before hitting the output transformer which is also custom made in the US with steel laminations like the original AP2503. Each preamp comes with 1% tolerance resistors as well as Vishay capacitors and the most accurate sounding 2520 DOA replica in the market! 

All tubes are auditioned and selected for the best possible performance, tone and specs. The Red Devil also features our own Stam aluminum knobs made in the EU. Each unit comes with phantom power, impedance and polarity switch and a built in DI. 

Sometimes strict adherence to an original design is absolutely called for, but sometimes an updated and improved version with the same great sound but more flexibility is just what a modern engineer or mixer needs. This results in the classic 312 sound but with a higher THD and bigger low end. The Red Devil is ideal for users looking to record electric guitars, drums, and hard vocals. All tubes are auditioned and selected for the best possible performance, tone and specs. 

Hand made in Chile

All units are hand-made at our lab in Chile which allows us to audition and measure parts prior to assembling them so that each of them sounds the same and is built with the same quality.
