I have 3 mandolins.
I keep one on the boat. It used to be my cheap mando but when I bought my 3rd my previous favorite found its way to the boat.
I used to only play when anchored out as not to disturb anyone else. Then after a particularly bad Memorial Day weekend, with the boat behind us playing bad gratuitous patriotic, country music till 0300 in the morning. The next morning at 0830 I pulled out the mandolin and while sitting in the cockpit played John Prine’s Your Flag Decal Won’t Get you Into Heaven Anymore.
when I finished a boat neighbor two boats down came over laughing and asked if he heard what he thought he heard, asking if I just played John Prine. When I confirmed, he replied that he assumed it was in response to the “idiots (his words not mine) last night” and then said, “well played”.
I assume he meant my smart ass response and not my actual playing.
that said, friends do ask me to play when the are on the boat. I also kept a Recording King parlor guitar on the boat for friends to play.
instruments are made to be played. Bring them and play them.But yes, maybe leave the $$$$$ ones at home. Beaters are easy to come by and for most people a cheap instrument will out preform the person playing it nowadays.
can we hear the difference between our nice stuff and our inexpensive gear? Sure. But when you are playing It is about the songs and the feeling it gives you and you friends/family.
you do you though.
