Professional bass player and sound man on a local level for several decades. While I was doing this, I had a day job working for a local chain of music stores. I started in a basic entry-level sales position and worked my way up to being purchasing agent with this company. Along the way I held many positions, often doing repairs on band, orchestral and fretted instruments. Oh, and I even moved pianos for a few years. ;)
I do all my own setups and repairs on my guitars, and for a few select others. These days I am pretty much retired, but I like sharing what I've learned along the way.
