For a description of any effects etc has already described t
So I pass.

I really appreciate being able to play with headphones and convenient USB interface

UTILIZATION

The general application config a little time getting started, but once you understand it's pretty simple. I still have the manual near me Repeat 'in case I have a doubt, but I do not open more often.
the manual is therefore just be a little careful and we do not talk nonsense.
The edition of the sounds / effects is very simple, after all the finesse and personnailt SETTINGS takes time to find the sound you want. but it's the same on all multi-effects.

The manual is super clear and very accurate I find, that much can study what you want to do or how to do it before emptying the machine.

I put 9 because it's clear, precise, intuitive and easy to use as possible.

SOUND QUALITY

The effects are generally effective, I do not have all the boards in-depth test but what I studied my satisfaction. Until present I use the flanger, delay, reverb, a distortion, a little tremolo and amp simulations (particularly for the simulation lamps zoom).
I do not know what to make of amp simulations having never used until the present. When I record I use my amp with a microphone in front, but the amp simulation lamps made me happy for models in home studio.
I used five days ago for a gig in a bar, plugs directly into a table via the DI WAS nickel in nickel.

My bass electro for my group (an Aria Pro II JLB two 90s) was quite a blast or noise function ZNR helps me remove it, keeping a possibility to change the 'equalization directly on my bass so very practical. But I think that not having to use it is still better, finally it works well.

So it all seems very complete and convince at least for the price, the fact ca

OVERALL OPINION

I use it since July 2006.
Plus, the expression pedal, super convenient, especially since we can assign a specific function each preset very cool ca!
Connectors usb, super convenient for quick note taking on the computer.
DI output super convenient for playing in small bars with a table, being able to switch the mass is also great, and avoids a lot of problems last minute.
The pace is really convenient box with all its patterns to repeat at home to click that I was not necessarily before. It invites CRER grooves which we do not necessarily believe in repeating.
Right now with my band, we use it to repeat the click tracks for a record, everyone agrees that this is very practical.
There is no "white" between the sounds when you pass each other

In short I am extremely satisfied.

The little less (but you know when you buy it) is that there are only two switches to switch the other. In order to overcome that, I cr a song by her, and if I utlise a second, it is immediately after or before. With the expression pedal ca still allows much juggling with the feet. Is therefore well prepared his set once roll faitca.

I find strong and beautiful.

I have not tried many multi-effects before. I was ready a pod for a while pretty good, but I came back.
I had an old Zoom 1010 guitar that I used with my bass, and I got to sound pretty good, because I mastered this background B2.1U replaces it quiet when I autat of mastery above, it will go perfectly.

I ream by repeating 'and in concert (acoustic, electric), all is well.

Report price very very good quality for the price I am very happy.

With experience, I would look out for what is, but I probably would resume this one.
And despite all the harm that some think of Zoom, the products I had in my possession I have always been satisfied.
