Lots of finished updates coming here in the weeks to come!!!
As I’m starting to scale back from building, I’ve been knocking out some personal projects that have been backlogged at the shop. Kicking things off is a new neck I made for this very special Custom 4. ————-

I made this bass years ago for my lovely wife Mallory Seisser - The top is from a log of Red Cedar that we found in her Grandmas attic in St Joe, MO. The original neck was Mahogany/Bloodwood and unfortunately developed a really bad twist over time. I decided to make a new neck for this bass to give it new life. I loved the way this Leopardwood fretboard tied in with the Red color themes in the bass. And you can never go wrong with Wenge. 💪🏼

These two Passive 4 strings are still looking for a new home to lay down some low end. Classic tone meets modern ergonomics with beautiful natural wood accents. I have a couple more stock instruments slated but availability is getting slim. Sn**ch one of these basses at a great price now. 🆕

Time for another repair shop dump. Sometimes you work on rare vintage jazz basses, sometimes you work on boutique bangers, and sometimes you work on hello kitty guitars. I don’t judge… I just set it up so it plays like butter, regardless of the finish. Message for more info about getting your guitars or basses setup for this hot summer weather. ☀️☀️☀️

Time for another repair shop dump starting with this very special Suhr. Not only is it special in its unique build specs, but also personally special to me. This guitar was previously owned by Chicago session great Tom Logan. Unfortunately, Tom recently passed and many of his guitars ended up for sale on the market. Tom had A TON of guitars… he used to joke that I would have to name a wing of my shop for him for all@the repair work I did for him. This guitar was one of Tom’s favorites though, and I did many a setup on it thru the years. I never expected to see this guitar again… but another customer of mine, Dave, brought this thing out of a gig bag and requested a setup. Dave bought this from Tom’s estate knowing it was one of his favorites. So cool to have this full circle moment and know that beautiful music will still be made on this instrument. 🥲

This magnificent beast of a fretless is still looking for a new home. Worried about intonation? Well there’s nothing to be scared of here with partial fret lines on the side of the fingerboard (side dots standard positioning) and 12-24 dots on the face to help with those tight spaces in the upper register. The Figured Satinwood fingerboard really shines in person on this one. Tone for days with more tonal options than you would expect from a passive bass… thanks !!!
