The TPA-1 is a digital emulation of a class AB tube power amplifier for guitar.

It has been designed and developed to be paired with any guitar preamp (VST/AU or even hardware).

Its circuit is not based on any particular physical power amplifier, but it has been designed to have enough versatility to range from vintage to modern tones, letting the user be free to shape its dynamic behaviour with ease, without the need to be a tube amplifier tech.

Every single component on the signal path of the analog circuit has been taken into account and modeled in the best possible way to match the original sound as it was meant to be, while keeping an eye on CPU performances and real-time playability at the same time.

The TPA-1 is meant to be used as a guitar tube power amplifier simulator for live playing and jamming, tracking or mixing inside hosts capable of VST or AU Plug-Ins support.

TPA-1 is free and is available for Windows and OS X, in VST/AU formats, for both 32-bit and 64-bit systems.
