True-Grit is a tube saturation processor that allows for very soft and progressive saturation up to full overdrive. A Low-cut filter before the tube and a High-cut filter after the tube allow you to define the saturating frequency range and adjust the amount of harmonics. Finally, a Blend control sets the mix between dry and wet sounds.

Install it in your API* compatible Lunchbox^TM or rack and start working.

Highlights

• Based on two "real" triodes in push-pull mode,
• Very progressive, warm and euphonic saturation,
• Goes into full overdrive when using the Boost function,
• Optional, variable frequency Low-cut filter before tube controls the saturated frequencies,
• Optional, variable frequency High-cut filter after tube controls the amount of harmonics,
• Blend control between clean and saturated sound,
• Can be used as an instant soft peak limiter, increasing loudness without compression,
• Can be used as an enhancer, adding sparkle to a voice or an instrument,
• Hardware relay bypass,
• Available assembled or as a full kit.

Sine - Each trace is a 6 dB increase at the input

Triangle - Each trace is a 6 dB increase at the input

1: DRIVE Sets the level of the input signal thus controlling the saturation level.

2: BOOST Adds another 20dB boost to the input signal going into strong overdrive land.

3: LEVEL Sets the output level after saturation.

4: HI-CUT IN Inserts the High-cut filter.

5: HI-CUT Sets the frequency of the High-cut filter.

6: LO-CUT IN Inserts the Low-cut filter.

7: LO-CUT Sets the frequency of the Low-cut filter.

8: IN Module bypassed when up, module active when down.

9: BLEND Sets the mix between clean and saturated sound.

What's in the kit?

Absolutely everything!

• Passive components (resistors, capacitors, inductors),
• Active components (tube, diodes, transistors, IC's),
• Control elements (switches, potentiometers, switches, knobs),
• Connectors, relay,
• PCB's,
• Front panel,
• All hardware.

You bring the solder (use good quality solder, 1mm diameter max) and the Lunchbox.

Difficulty level

The True-Grit kit is a medium difficulty kit. It can be undertaken by anyone who is able to make a clean solder joint.
