    TPA-1 – free tube power amplifier VST released


    Ignite Amps has announced the release of TPA-1, a free VST/ AU 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.


    • Dynamic EL34 / 6L6GC / KT88 pentodes/tetrodes analog modeling (push-pull stage).
    • Dynamic ECC83 / 12AX7 triode analog modeling (phase inverter stage).
    • Mono / Stereo processing support.
    • Selectable oversampling rate (up to 8x).
    • Global input / output level controls.
    • Double precision (64-bit) floating point mathematical model.
    • Fully automatable controls.

    TPA-1 is available at no cost.
