If you work that tune up you won't regret it. Your crowd will say "wha.....????
I started playing lead guitar in my first group in 1962, two guitars, bass and drums. I was in the USAF and we didn't even have a PA set, so we were doing lots of Ventures tunes and other instrumentals.
One night we played at a club that had a mike and a house PA and the bassist wanted me to play his axe so he could sing a tune. He had to show me exactly what he was doing during the break, and we did the next set like that. I thought, "I LOVE this!" As soon as that group broke up, I traded all my stuff for bass equipment and never looked back.
