AnaMod® XF Tube

Dual-Stage Transformer and Vacuum Tube Amp Simulator

  • Versatile modeled tube amplifier
  • Selectable Iron and Nickel transformers
  • Selectable Triode and Pentode tubes
  • All analog—no latency or digital conversion
  • Single space 500 series module

Whether tracking live instruments or re-amping existing recordings, many engineers use a tube amplifier to shape the sound of a track. The AnaMod XF Tube provides a unique way to do this in a highly controllable fashion.

The XF Tube is an analog model of a highly-configurable amplifier. It provides an input transformer, 2 tube stages, and an output transformer. Any of the stages may be bypassed and each stage has switchable parameters. The transformer stages allow for the selection of an iron or nickel core while the tube stages provide options for both pentodes and triodes as well as configuring the stage as either push-pull or single-ended.

The XF Tube, while being model-based, is a purely analog device. It was created using The AnaMod Process™ to model the complex tube and transformer characteristics of vintage amplifiers. Unlike digital plug-ins or processor-based outboard gear, there is no latency and no A/D or D/A conversion to compromise the sound.


“Dude, I had no idea. What a brilliant box. I can‘t believe a 500 series module can pack the sound of a tube desk!!”
