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.
- 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.

This is an absolute gem of a plugin! I've never owned a separate guitar poweramp but I image this must be a really good approximation of how it would sound. My normal use for this is with a ampsim plugin that don't have a built in poweramp, Ignites own The Anvil and Mercuriall SS-12 are examples of this. It's also great to use on ampsims where you can bypass the built-in poweramp simulation.
Note that this one is not supposed to be used on it's own but in a signal chain after the preamp but before the speaker cabinet emulation. A typical scenario would be something like this:
Guitar input --> (Pre-FX) --> Preamp --> TPA-1 (poweramp) --> Cabinet simulation (IR loader) --> (Post-FX).
On the front panel you have controls for volume, depth and presence. Increasing the volume gives you that nice poweramp saturation that to my ears sound really pleasing. Depth controls low-frequencies and presence (as usual) high frequencies.
Looking at the back of the plugin you find controls for:
- tube bias voltage.
- amount of sag.
- feedback level (the amount of signal that goes from the output back to the input).
- choice between different models of power amp tubes (EL34/6L6/KT88).
- feedback (a model of the interaction between poweramp and speakers) and.
- overall output level.
Tweaking the bias, sag and feedback controls allows you to have very detailed control of the poweramp characteristics and also how it feels to play.
Feedback control settings are dependent on what type of IRs you use - your really should read the manual for best results here :).
This is a great sounding power amp simulation with an outstanding level of tweakability. As far as I know there are no other dedicated VST powerampsims, so there is really no competition to compare it to. Hopefully someday someone will model a MESA 2:Ninety or something similar. But the lack in choice is not a problem when the only choice you have is as good as the TPA-1. Big thanks to Ignite for giving this away for free.
Ignite Amps updated a number of plugin to a new major version in 2018 at the same time incorporating newer modelling technology - I'm very much hoping that this plugin receives the same treatment.Read more

I absolutely love the tone/character/saturation of this thing. I don't just use it with guitar. Along with Sonimus Britson (Vintage Flat), T-Racks EQ 81 and and EQP-1A it is on every one of my tracks in a mix. The blend of these four ingredients in my spice rub makes everything sound delicious to me. Ignite Amps is incredibly generous to offer the TPA-1 for free.Read more
