@Mouse and others. I am glad that you enjoy the cecilio cello and that it arrived unscathed. I enjoy mine.
I added Knilling pegs, opera (import) steel strings, and a 3/4 sized tailpiece to mine.
By all means try to introduce a metronome beat into the electronics sometime as you practice. Easily done. I often play it without earphones.
