Other error: wrong adjustment nut that is not well supported on the piezo at the high E, which affects the balance between the strings. Painful enough to correct!
Bient heard these defects only for the copy I bought, but it is a lot for a single guitar.
Fortunately the Fishman preamp is correct and enables effective settings.
never seemed very pleasant, easy to play better for electro, but the varnish has always bothered me in particular, and a plastic container makes a rather unpleasant feeling.
I could always get good sound, but no more.
The best use is for an electric guitar to apoint in a group rather than electric. I used it on the PA group, the Sound can get sounds that are detached from the whole group managed to make themselves heard without straining the volume.
Overall opinion rather negative because the build quality is really insufficient for the same price. Not to mention the concept, initially quite attractive to have a guitar handy and compact but at the expense of sound.
