Guitar maker Lukas Giefing

But how can I explain

playability,
response,
sound,
capability of modulation,
feel,
etc.. ?

It is impossible.

A guitar has to be experienced, heard and felt, ideally compared to an instrument you know.
This is something you can do in my workshop, I usually have some finished guitars here
- if you are interested, you are welcome.
