Vintage Collection · Tube program equalizer
Listn Tube EQ (LT-1)
Boost. Cut. Warmth.
A passive style program EQ with a tube make-up stage.

Boost and cut the lows at the same frequency to tighten the bottom end, lift the highs with a width control and shelve the top down. The drive control adds the tube; the pilot lamp lights when the EQ is in.
- Low boost and cut at 20, 30, 60 or 100 Hz
- High boost from 3 to 16 kHz, sharp to broad
- Top shelf cut at 5, 10 or 20 kHz
- Tube drive and output
The low end
Boost and cut at the same time.
Turn up Boost and Cut on the same low frequency. The cut sits a little higher than the boost, so the bottom gets bigger and tighter together: the old program EQ trick, on every track.

- 20, 30, 60 or 100 Hz
- Boost and cut together
- Gentle curves, no harsh filters
The top
Air that stays smooth.
Lift the highs anywhere from 3 to 16 kHz and set the width from sharp to broad, then shelve the very top down at 5, 10 or 20 kHz.
- Seven boost points
- Sharp to broad
- Top shelf cut

The tube
Drive it into the glass.
The tube stage adds the harmonics and the soft top end. Turn Drive up for color and use Output to keep the level where it was.

- Drive for color
- Output to match the level
The faceplate
Hardware you can see.
Brass knurled knobs, wing selectors, a bat switch and a pilot lamp, rendered as lit 3D parts. Drag up or down, hold Shift for fine moves, double click to reset, right click to learn a MIDI control.
