Yep - I know it’s not really a cello string. ;-)

I’m just curious because I’ve never heard that sound come out of my GFI (not that I play it that much).

Are you using a thumb pick when you get that “cello” sound? The attack sounds soft.

Thanks for your patience...

Thumbpick and two fingerpicks. Judicious use of the volume pedal. Volume pedal can make it sound like it’s a bowed string. May be just my touch,,,, don’t know. Never analyzed it.
