Two program EQs in one. Now they breathe.
A measured valve & transformer program EQ and a phase-honest Baxandall mastering shelver, sharing one signal path. Turn the unit over to hear the other voice. Then let Push-Pull move every band with the music.

One unit. Turn it over for the other EQ.
Same input, same output, same gain-match. TUBE and BAX are two full program equalizers behind one faceplate, so the flip is a built-in A/B between two ways of shaping the same record.


Weight, colour, iron.
A measured valve and transformer program EQ. Broad musical curves with the low-end heft and top-end sheen of the classic hardware, plus an IRON stage that adds real transformer saturation as you push it.
- LF, MID and HF program bands with boost and cut
- IRON drive: measured transformer and tube harmonics
- Dynamic IRON, so the colour follows how hard you hit it
Because both faces share the exact same in and out, flipping is the cleanest A/B you can run: colour versus clarity on the same source, gain-matched.
Every band moves with the music.
Push-Pull adds bidirectional per-band dynamics to both faces. Set a resting curve, then let each band lift when the signal is soft and ease back when it gets loud, or the other way around. The dashed line is where the EQ rests. The gold line is where it is right now.
Bidirectional, per band, on a full program EQ. Nothing else does this.
The plain facts, in order.
Every colour on the TUBE face is a measurement you can read on the analyser, not a mood. Here is what ships.
