I thought and planned for the echo machine a long time, finally deciding on this one after a lot of reading reviews and listening to advice. And it is good!
The sounds are great, the overall look&feel well designed, feels rugged and sturdy. So far the only thing to improve - that I can think of so far - is that if you use some of the "spacier" echoes in your solo or in an instrumental Shadows king of song, it would be good to be able to change to a "regular" reverb with a stomp of the box.
But now, with this baby, you'll need to bend down and select "reverb" separately, and maybe adjust the settings. I.e it will give you one nice reverb/echo sound at a time, which are all great as far as I'm, concerned, but for switching between a spacey vs. earthly reverb you'll need to go down and tweak with you hands.
But that's nit-picking probably. And it's proven to be great in gigs, too. Recommend!
