Feature:
Really strong machine . I use it a lot and haven't got any problems yet.

Quality:
Really strong, nothing fancy.

Value:
Very good value. I bought second hand in a shop for 100 euros. I think the price for a new one is now more than 200 . I would say it's worth the price if you need a strong reliable pedal , if you don't play that much in concerts or just want to have a pedal for home, have a look at zoom products , cheaper, more fancy sounds and gadgets. Work well anyway. But not the quality of the Boss.

Desirability:
The worst or the best apealing... So basic, but I like it like that.

Sound:
I haven't rate 9 because we will have something better one day. But not yet. More usefull with nylon strings guitars with piezzo than metal ones. Anyway, I use it every time I play plugged acoustic. It really helped me to control things in difficult sounding situations. The top and the bottom controls are more efficent than an equalizer.This pedal gives me what I need , an efficient sound in almost all situations, very easy to control and very stong heavy duty stuff. For unplugged, only in certain circumstances, I use a high quality guitar and I don't use any pedal of course. That's the engineer job, mic and sound...

Ease of Use:
No manual needed. So simple. Just select the proper output, guitar amp or PA.

Overall:
Great tool and Boss have been making it for years. Just perfect for me . I teach music at school , teach guitar after school and have gigs and concerts all year long.

If you really want a shimmering truely stereo chorus, then the AD-3 is the pedal for you. The reverb is a very vintage sound, it doesn't make the guitar sound thin. You control the amount of attack you want.

Quality:
This thing seems to be built like a tank!

Sound:
I was blown away by how it enhanced my Taylor guitar. I had been pretty protective of my guitar's own sound, but this was a very sweet surprise. It doesn't take away from my guitar's own personality, but makes it shine much brighter. It has truly enhanced my creativity!

Support:
N/A

Feature:
Very simple and direct...not too much to worry about or jack with it.

Quality:
Built great, should last a while.

Value:
Just don't think it provides anything of great sound or tone.

Desirability:
I wouldn't buy it again.

Sound:
Doesn't do much for my Taylor with an ES, my Takamine with a piezo, or my PRS Hollowbody II with piezo. Just sounds like crapola.

Support:
Haven't needed to use it.

Overall:
Eh, I would look for something else if you are wanting to enhance acoustic tone.

We used to play three acustic guitars with trio vocals, for a small room/audience we never had a problem. But when we play for a big audience we used to had a problem to get a good sound beetween the guitars and vocals even we play electric guitar. Lately we are saved by AC3 to get balance sound even we play for a big public
