Small magic box, a sort of mutli effect / travel headphone amp that can power cell and even fix his belt.
The Rockbox is fairly complete: amp simulation in its clean, crunch and distortion, chorus, reverb / delay (adjustable e), compression, gain control, level of distortion and noise gate, this proves that quite useful because the machine is enough wind.
In addition we just connect another source in parallel, and is equipped with a connection send / return I've ever used.
The simulations are good, especially clean sound: jazzy assured her with a little reverb and it's a real treat.
The chorus is stereo but is more reminiscent of a receiver and that of a max-tune, too much for my taste!
The breath is a little too imortant to use rockbox recording but this is not its primary function.
I've used it since 1990 and as much at first little amp for the holidays. Now it takes a bit the dust because I am using an acoustic guitar.
I try recently and spitting out small, it works like new.
