About Studio Devil


Studio Devil is a virtual tube amplifier processor based on dynamic models of vacuum tube preamps and power stages. While primarily intended for guitar amp modeling and direct recording of both electric guitar and bass, Studio Devil excels wherever natural tube overdrive and distortion is needed.



Virtual Tube Amplifier Technology


Tube preamp on the test bench with the Variac... Studio Devil's patented vacuum tube emulation technology is the result of a passionate quest to reproduce the inspiring tonal character of coveted tube amplifiers.  Recognizing that virtually all tube amps are built using preamplifier stages based on the 12AX7A triode, we believed that if we could emulate this preamp stage then we could configure our software models to reproduce the effects of virtually any tube amp.

12AX7A Triode... We began by physically building actual 12AX7A tube preamps.  By taking electronic measurements of their distortion characteristics, we were then able to develop digital signal processing models to mimic these distortion curves so that they could be emulated in an audio plug-in.  We spent time tweaking and adjusting the components of these preamps to discover how they affect your guitar's sound, and we incorporated this into Studio Devil.

Actual Tube Amp Schematic... With our accurate tube model in place and sounding great, we returned to the schematics of some of the world's best tube amplifiers to learn the best ways to configure and chain our tube models together.  We selected a handful of coveted amps to represent the various guitar playing styles that Studio Devil delivers, and we used their schematic drawings to configure our plug-ins to reproduce their sounds faithfully.

Digital soft clipping... To add the finishing touches, we researched the behavior of push-pull power amplifiers and the spectral responses of several speaker cabinets and professional guitar recordings to integrate them into our virtual guitar amp emulators.  This gives Studio Devil the professionally recorded sound we're all after...like it's being played through a real amp, with a real cabinet, with some real good production.

So, it's no surprise that Studio Devil sounds like the real thing...it comes from the real thing!   Download Studio Devil today...and plug into a true virtual tube amplifier...and hear how good it sounds for yourself!
