Updates DIY Electric Cello - adjustments for upper positions.

After starting to play on high notes on the A string I found hitting the notes with accuracy is difficult without some sort of marker for the left arm.

On the acoustic cello, players use the body of the cello to support the left hand on the upper positions.

For the electric cello I added a thick rod to act as a hand support and landmark to find the upper notes with more accuracy.

 The back of the neck also has landmarks for the thumb in hand positions 1 to 4th.

Using 2 jack connectors as options for plugging in.
Removed all electronics from the body(old preamp failed). Sensor is plugged in directly to a guitar amp.

The piezzo sensor position is as close as possible to the C string. This seems to yeld the best sound compared to other placement options.
