I just had a Lyric installed in my Eastman E20-OM today. I'm connecting it directly to my Fishman Loudbox Artist acoustic amp.

What is the maximum length of cable I can use before the sound is affected?

I would assume shorter is better, but I would like to understand what might happen to the sound, in general, if I use a 10 foot vs. an 18 foot cable, or longer.

For now I'm connecting directly to my amp. But there may be a time when I have a device or two between my guitar and amp, and I'd hate to trash my sound by accidentally using too much cable.

Thoughts?
