I ordered this item for the simple reason it has a lot of features in 1 pedal.
Tuner, booster and you can split your signal to 2 different amplifiers, it even has a ground lift to reduce the noise when you run 2 amps.
The tuner works like it should, no problem here.
The booster is very good and has a lot of output, you can choose between a full frequency boost, a 720Hz and a 1K option.
The full frequency boost does what it says, everything louder or more signal to your amp. the 720Hz is basically a TS style boost and the 1K is a Klon type boost. I tried all of them and the 720Hz was my favorite, it's like a TS but with a lot more output! The 1K makes my wooly amp (Orange) very tight and with a lot of presence.
The only minor on this pedal is that the footswitches are really close to the gain knob, and the gain knob is very sensitive so I find myself turing the gain knob a little bit when pressing a footswitch, but nothing a little bit of tape can fix when you've got the gain control set to your preference.
The pedal has a very sturdy enclosure and is roadworthy!
