I got several different clip on tuners to test on my guitars and basses and this one is one of my favourites.
The good:
- It feels very solid, not plastic or cheap at all.
- The display is very crisp and bright.
- It's very quick to find the pitch.
- It can handle 8 string guitars and bass without any problems.
- Automatically detects the right orientation.
- You get a free AU/VST tuner for your DAW if you want. I already have several so I didn't bother with that though.
The bad:
- The poly thing is a bit hit-and-miss. It only works semi-reliable for 6 string guitars in standard tuning.
- It's one of the bigger ones, not easy to hide behind the headstock.
- It's a bit pricey.
Summary: If it was a little bit cheaper I'd get this one for all my guitars. For now it's going to be my go-to for extended range and bass.
