Not rated yet

Tube Saturator Vintage is a free reissue of Wave Arts' original Tube Saturator, simulating a preamp with two 12AX7 triode stages and a Baxandall 3-band EQ.

Drive, a FAT mode for extra punch and an EQ bypass keep it simple, with no latency.

Best for: Guitars, Bass, Drums, Vocals, Keys & Synths. Genres: all genres.

What it does

Tube Saturator Vintage is the original Wave Arts Tube Saturator, now given away free. It uses 64-bit circuit simulation of a basic circuit: a Baxandall-type 3-band EQ feeding two 12AX7 triode preamp stages. Wave Arts notes it was CPU-hungry, which led to the more efficient Tube Saturator 2.

Circuit: two 12AX7 triode preamp stages, simulated component by component rather than with a static curve.
Drive: raises the input gain and lowers the output gain together, so you change the amount of distortion without a big jump in level.
FAT mode: changes the bias of the first preamp stage for more gain, punch and saturation.
Baxandall EQ: a 3-band tone stack ahead of the tubes, so it shapes what gets saturated; it can be bypassed.
Metering and latency: analog-style meters and no added latency; mono or stereo at up to 192 kHz, CPU permitting.

When to use it

Tube Saturator Vintage is the pick when you want a realistic tube preamp that reacts to level and frequency content, and you don't mind paying for it in CPU. Compared with Softube's Saturation Knob, it is slower to dial in but behaves more like a real circuit, and it adds a 3-band EQ ahead of the tubes. Unlike Decapitator, which offers several fixed characters and a mix control, it has one tube sound with a FAT switch and no wet/dry blend. It is free, where Decapitator and most of the rated saturators are paid. Its own successor, Tube Saturator 2, adds the 12AU7 tube, 2x oversampling and a wet/dry mix while using much less CPU.

Best for: free tube warmth on drum buses, overheads, vocals and the mix bus.
Genres: general purpose; rock, pop and any style where subtle analog colour helps.
Look elsewhere if: you need parallel blend, oversampling or low CPU use; Tube Saturator 2 or Saturation Knob suit that better.
Tip: because it is CPU-heavy, a Musco review suggests committing the effect by printing the track rather than leaving many instances live.

What producers say

Users like its realistic, musical saturation, with CPU use as the main drawback.

KVR users rate it 4 out of 5 from 2 reviews; one said its saturation on cymbals and snare "is amazing" but flagged high CPU use, while another liked the EQ but saw it as situational.
Michael Musco review (2026) praised how it "responds dynamically to input level" and builds harmonics gradually, adding cohesion on buses, but found it CPU-intensive, slow to work with and lacking a mix control.
