The Tubester-1 plug-in is a combined preamp, EQ and guitar speaker simulator. The sophisticated amp model is a 3-stage, 3-valve preamp with input and feedback filtering implemented to match original 1960's designs. Preamp tubes are physically modelled on actual Mullard EL83 triodes.
An EQ section gives fine control over bass, mid and treble bands (at 100Hz, 300Hz, 750Hz with ± 20db of boost and cut) with a presence control at around 5KHz for additional control over tonal purity.
Tubester-1 is a zero-latency, highly efficient implementation with minimal CPU overhead, and is thus suitable for real-time, live use.
Tubester is free and is available for Windows as a VST plug-in.
