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
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.
