That's some serious mando action! I recently picked up an electric mandola, and it's a blast. I use it in more of a guitar way, but the 5ths tuning takes away all your familiar fingerings, etc., so that sparks new ideas. I can barely pick it up without spontaneously coming up with a new riff or song idea. Kinda funny cause I've always said the same thing abut my 8 string bass. Something about those double courses... My next adventure will be a 12 string guitar/mandocello hybrid. Mandocello low strings - cC gG DD AA, with the top two tuned to regular guitar BB EE. I tuned my 6 string like this for a few years back in the 90s and really liked it.
