Two models
Triode: soft, even-harmonic warmth. Iron: a transformer stage that saturates the lows first.
Live harmonic fingerprint
The evens and odds your settings produce, at the level you are actually driving, while the music plays.
Loudness-matched auto gain
A/B is about character, not level: the wet path glides back to the input's perceived loudness.
Delta listen
Solo the difference between input and output to hear what the valve contributes. With bypass on, delta plays silence, which doubles as the bypass test.
Multiband drive
Two crossovers, three regions, one latency on every path.
| Formats | AU, VST3 |
| Latency | 48 samples, reported exactly |
| Oversampling | 4x, polyphase FIR |
| Models | Triode, Iron |
| Factory presets | 6 |
| Channels | mono, stereo, mid/side placement |
Measured behaviour
At maximum drive with a 7 kHz tone, the bare stage keeps the worst alias fold more than 80 dB below the fundamental, and a test locks the full plugin path above 60 dB on every build. Small signals pass at unity in every model.
Two more models, Pentode and Vari-Mu, arrive later as a paid addition. Triode and Iron stay free, and nothing you save today will ever remap: the model parameter reserves all four slots from day one.
