Sound — 10
This is fairly irrelevant as it does not effect your tone, I know Boss pedals are meant to have bad bypass but I have not noticed it with this pedal. I use it with an Ibanez RG through Cube 30.
Overall Impression — 9
Is a great pedal, does all it needs to well, nice package, bright LED's great Live, don't know how I managed without it before. However it is very expensive I mean 60 for a tuner I know it's in a pedal but still when you can get a regular tuner for about a tenner this seems a lot. definitely overpriced. the only other disadvantage is I was hoping to be able to use it to power my DD20 however using the Boss adaptor it can only supply 200ma which is not enough for the tuner and Delay, however this is not a problem with the pedal, just be warned if you plan to power your whole pedal board from it!
Reliability & Durability — 10
Its a Boss pedal so it's built like a tank! very tough no worries about reliability, wouldn't want to stamp on the screen though. would use without a backup.no problems so far.
Ease of Use — 10
Is incredibly easy to use stomp on it and line up the dots, 2 options of display, stream and cent. I find cent much easier basically tune till the green LED lights up, in stream a stream of leds flow across the screen right for sharp left for flat and stay still once your in tune.can also select tuning mode. chromatic, where it displays the note name closest in pitch to note played, guitar mode, displays string number, guitar flat same but for Eb tuning, Guitar double flat for D tuning, and the same for Bass, it claims to work for 7 string guitars too allthough I have not tried this as I do not own one. Chromatic mode is most useful in my opinion. also mutes the signal when stomped on which is very useful to tune in silence or just to simply be quiet in between songs or whatever. I find it to be very accurate and useful. can change frequency of A if you want too, not sure why you would but it's an option. also has the ability to power several other pedals using the same adaptor such as Boss, MXR, Ibanez etc using the daisy chain,
