The rglages: volume, bass rglage 1, 1 treble, reverb 3-position: a free, one short and one long, rglage effect send, headphone (walkman book with headphone - atria), to take in, output jack.
On 9V battery (not included) or AC power, transformer Deliv. The Clisse dmontable left, the guitar takes up half the width.
Like all Yamaha, with a play book 12'54 '(light). The cover is provided.

UTILIZATION

Frankly, does not look like a guitar, but it is not at all palm. They are adding support for fans of arpges posing their little finger (not visible in the photo above). The shape of wicker covers can have the illusion of holding a sche.
The ergonomics are good. I feared the loss of most back, and no problem. The handle is easy to play. It rises in the treble without problem, forcment ...

SOUNDS

I do not play that headphone: if not, why buy a scratching silent ... The sound is that of a good quality electro Yamaha. It is not transcendent, but there is no major default. Comparing with a Takamine electro EN10C is below - it plutt reassuring.
THE FIRST reverb is short, I use it constantly, otherwise it's really too dry. The deuxime is too long for the rhythm, but fans of folk ballads arpges or navigate.

OVERALL OPINION

I use it for a week, it's perfect. I test the nylon, trs crdible too. I love this scratching for what it is: practice, play all night without rveiller person rpter fifty times the same riff without giving a headache to the neighbors.

No use in making studio, simply because I ask prfre a microphone to capture the true sound of the real guitar.
Only got my default: the price. Even so, buy a guitar that is not quite made a 600 ...
