I don't have the StroboPlus HD, but I do have an old StroboStomp (the original version, I think), the VT-1, and the 490 Autostrobe. They are all incredible tuners. My guitars have never been intonated or tuned nearly as well until I got the VT-1. I added the StroboStomp for my pedalboard and the 490 for a larger version. The backlight for the strobe disk on the 490 is blindingly bright, but that's the only complaint I've ever had about any of them.
