Stax Harmonizer Guitar Pedal Digital Guitar Effect Pedal Harmony Pitch Shifter Detune for Electric Guitar Bass Mini Size True Bypass

I bought this with the sole purpose of using it as a pitch shifter for 1/2 step down tuning (E flat Standard). I was planning to use it in the "down" setting and have the dry signal all the way down and the wet signal all the way up. Just for anyone wondering, it will not work for this. The latency is pretty bad. It does pitch it correctly, but the delay makes it unusable for this purpose. However, the pedal itself is good quality and if using this for harmonizing (as the name implies), I'm sure it does a good job for the money. Just sharing this info in case anyone else is looking to do the same. If you need pitch shifting on a budget, get the Mooer Pitch Box. Works great and the latency is far shorter (actually useable in most if not all instances). Can't fault this product, but can only fault my desire to save a few bucks.

All harmonizer pedals in the 100 minus range suck. Just don't bother. They shouldn't make these. Stax is a great company but a quality, AND inexpensive harmonizer pedal is just something that doesn't exist. Right now there seems to be nothing we all can do about it. That's all there is to it. You've been told. Veteran 40 plus year semi pro player telling you this.

Like many people, I bought the Donner Harmonic Square after seeing it on 60 Cycle Hum's "Afford-a-board". Well, this is basically the same thing, just a little cheaper and a little cooler looking. It's a great pedal, and if you're into things like Shoegaze, I actually prefer leaving this on a -2 detune vs. a chorus. It sounds similar, it just doesn't "move" like a chorus does, which is better when it's in front of [a metric ton of fuzz].Can't beat it for the price!

So the good stuff. It is a great sounding Plexi in a box that does an amazing job of replicating Marshall tones in a tiny package. It sounds good going into the front of a clean amp, it sounds good as an amp sim with a cab sim going direct, and it sounds good in the return of an effects loop as a pre amp. It plays nice with other pedals, loves a clean boost, can go into JCM 800 territory gain wise, and has a bright and normal modes activated by a switch. Great glassy mid range roar, and the tone control is useful thru the whole range, and to my ears adds upper mids along with treble, and cuts low end when turned to the right, and does just the opposite going left. Loves my strat and my ES 339 so both single coils and humbuckers, it cuts right thru the mix. The only issue I have, and lots of mini drive pedals in this price range have this issue, is it is extremely loud, lots of headroom, which is great, but this comes on instantly when you turn the level control, at 7 o’clock it’s way louder than the clean signal, so it’s tough to get unison volume from the amp and pedal, especially going into the front end of a tube amp. I just use a clean boost to raise the clean channel to match, but still it takes awhile to find the sweet spot..

While the unit seems decently put together and the character of the sound is good, the wet sound noticably trails the dry. I'm guessing somewhere in the 40ms-50ms range, such that you hear a second attack almost like a tiny plate reverb. I got it to pair with a swell pedal for ambient sounds anyway, so the lag is not a dealbreaker for me. However, it does make it unsuitable for some other uses - like fattening up with the detune or shifting at 100% wet for transposition. Given the price point, I'll still get my money's worth from it as a specialized piece. Consider your use cases carefully though.

This is a great pedal with a lot of range but maybe a little too much range. You really need to try it to see if you could use the sounds. The ranges it has to offer are more than other harmonizer pedals in its price range and some for me were not of use. There was no line noise when hooked up to an amp. They say polyphonic but not true multi-note polyphonic but two at a time and more than that sounds like a mess. I returned this pedal because it was not a fit for my music but my rating truly reflects on the product and what you are getting at such a reasonable price.

The effects are the greatest effects ever, but with a tuner and a looper, I think it’s ideal for my son getting into effects. The looper is solid by itself and worth the price. Recommended.

The good: The harmonizer is a beautiful looking pedal that doesn't take up much space. It's got a slew of awesome (but uncomplicated) features and is dirt cheap.The bad: There is major latency in the wet signal that makes combining both the dry and wet channels sound like a crummy reverb pedal with an arbitrary delay setting. I thought I received a defective pedal at first, so ordered a replacement - but that has the same issue.This makes the pedal unusable (unless you're going for a wacky experimental sound). And if you're intending to use it to simply to detune your guitar, then I suppose you'd need to rush your notes in order to stay in time.You'll notice on the preview video that they never activate the dry signal in conjunction with the wet, so I suspect Stax is aware of this issue.
