- Weight3.85 kg
This unit uses a tube circuit to add warm harmonic overtones to your signal. It lets you shift frequencies forward or backward on the stereo stage for a wider image. While the heavy weight makes it tough to move around, the built-in bass boost and tube warmth make it great for live sound.
Pros
- Moves frequency ranges forward or backward on the stereo stage
- Adds harmonic overtones through a dedicated tube circuit
- Includes a specific downstream bass boost feature
Cons
- Heavy at 3.85 kg for transport and stage use
- No input or output connection types are listed in the text

The Vitalizer Mk3-T is a clever piece of kit, adding a polished sheen and subtle character to stereo mixes. It's perfect for engineers looking for a quick, intuitive way to enhance presence and widen the stereo image without resorting to complex EQ chains – especially good for rock, pop, and electronic genres where a bit of extra 'air' is needed.
Pros
- The Sovtek 12AX7 adds a genuine warmth and harmonic richness.
- LC-EQ provides surprisingly precise mid-range shaping capabilities.
- Bass Sound control offers a genuinely useful tonal palette for bass frequencies.
Cons
- The size and weight (over 6kg) make it impractical for mobile setups.
- The 'Process' control can be a bit vague and require careful tweaking.

The SU9920 is a quirky little box that genuinely can add some heft and clarity to a thin-sounding mix, especially for bass. It's not a replacement for a good EQ, but as a subtle enhancement tool for DJs, keyboardists, or home recording setups on a budget, it's surprisingly effective. Don't expect miracles, but for the price, it's a fun experiment.
Pros
- Adds subtle warmth and perceived loudness to weaker signals
- Phase compensation genuinely tightens up bass frequencies
- InLow Contour control offers surprisingly nuanced low-mid shaping
Cons
- Build quality feels plasticky and somewhat fragile for rackmount use
- Limited versatility; specialized for bass enhancement, not general FX

How to choose the best psychoacoustic effects
Stereo Imaging
This is the big one - how convincingly the effect widens the soundstage. Cheap units often create a hollow or phasey effect that collapses under scrutiny. A good unit will feel natural, even when pushed.
Dynamic Response
Psychoacoustic effects shouldn't be static. They need to react to your playing's dynamics - subtle swells should be accentuated, hard picking should remain punchy. A sluggish response ruins the illusion.
CPU Usage (for plugins)
These effects can be surprisingly processor-intensive. Some algorithms are just inefficient. Check the CPU load, especially if you're running a DAW with a lot of tracks already.
Artifacts & Noise
Subtle artifacts can instantly betray a psychoacoustic effect. Listen carefully for phasing, pumping, or unwanted hiss. A little noise is acceptable, but anything distracting is a dealbreaker.
Musicality & Versatility
Does it sound good? Does it offer enough control to fit different genres and playing styles? A great psychoacoustic effect is subtle enough to be useful in a variety of situations, not just a novelty.
Buying guide
Ever wish your guitar sounded wider, more present, or just...different? Psychoacoustic effects aren't about physically altering the signal like reverb or distortion; they're messing with how your brain perceives the sound. We're talking about subtle tricks that can make a mono track feel like a stereo field, or add perceived sustain without actually extending the note. They're a surprisingly powerful tool for both live players and studio engineers looking to add something extra without resorting to drastic changes.
Psychoacoustic effects are often a case of 'you get what you pay for.' The cheaper units tend to rely on simple algorithms that sound artificial and can introduce unwanted phasing or a weird 'swimmy' quality. Spending a little more usually gets you more sophisticated algorithms and better control-things like adjustable width, mid-focus, and different stereo modes. Don't chase the 'widest' setting; subtlety is key here-it's about enhancement, not gimmickry.

Questions
Are psychoacoustic effects the same as chorus or flanger?
No. Chorus and flanger are modulation effects that physically alter the signal. Psychoacoustic effects trick your brain into perceiving changes without physically modifying the waveform.
Can I use these effects live?
Absolutely! Many are designed for live use, but be careful with extreme settings. Too much width can make you disappear in a band mix. Use them to add subtle presence and clarity.
Will these effects make my guitar sound 'better'?
Not inherently. They're tools to shape perception. Used well, they can enhance your tone and make it more engaging. Used poorly, they can make it sound weird and unnatural.
My cheap plugin makes my guitar sound super wide - is that good?
Probably not. That 'super wide' sound is likely phasey and will collapse when you add other instruments or run it through a PA. Subtlety is the goal.
What's the difference between a binaural effect and a stereo widening effect?
Binaural effects are specifically designed to mimic how sound is perceived through headphones, creating a very immersive (and sometimes disorienting) experience. Stereo widening effects aim to create a wider soundstage in a traditional speaker setup.
