Stereo Doubler
Very short delay that thickens and widens your tone — like two guitarists playing the same part slightly out of time.
What it does
The Stereo Doubler uses a very short delay (up to 100 ms) to create a second, slightly delayed copy of your signal. When the original and delayed copies are panned apart in the stereo field, the effect sounds like two separate takes of the same part played slightly out of sync — a technique used in recording studios to thicken guitar parts. Unlike a regular delay, doubling delays are too short to be heard as distinct echoes; instead the brain fuses them into a single, wider, thicker sound.
Parameters
| Parameter | Range | Default | What it does |
|---|---|---|---|
| Time | 0–100 ms | ~20 ms | The delay time of the second copy. 10–30 ms is the classic "doubling" sweet spot — the copies blend into one wide sound. Very short times (< 10 ms) create a chorus-like thickening; longer times (40–80 ms) begin to sound more like a slapback delay |
| Mix | 0–100% | 50% | Blends the delayed copy with the original. At 50%, original and copy are equal in level, creating the widest stereo image. Reduce for a subtler width enhancement |
Tips
- 20 ms is a great starting point — well within the range where the ear considers the two sounds to be the same event playing in different places rather than two separate notes.
- Use the Stereo Doubler after the cab IR to widen the final tone. Placing it before the amp processes a mono doubled signal through the amp, which can thicken saturation but loses the stereo width.
- Pair with a panned chain — to hear the full effect, make sure your monitoring output is stereo. In a DAW, the double is most audible on headphones and stereo monitors.
- On mono playback (e.g. a phone speaker), the Doubler adds subtle thickness through comb-filtering — still useful, just more like a chorus than stereo width.
- Keep Mix at or above 50% for maximum impact. Below 30%, the doubling effect is minimal.
