I have recently been playing quite a few traditional jazz gigs and have been wanting to set up a bass with strings more suitable for that style of music. My basses are set up with Spirocores and have a more modern vibe than I was wanting for the trad gigs. I did some shopping around and found a guy with a new condition Thompson hybrid close by. I went last night and tried the bass out and was surprised by how good it sounded and the very great set up that had been done on it. The bass has Spirocores on it and sounds very good....really close to my fully carved Wilfer. I bought it for a fair price. I decided to leave the Thompson as it is and this morning I put a set of Jargar strings on my Upton Standard laminated bass. Quite a change in tone from the Spiros. It sounds much darker and has the thump I was looking for. I will try it on my gig tonight and see how it goes. Meanwhile, I am very impressed with the Thompson and the set up it received at String Emporium. I'm appreciating the great tone and feel of the bass. Quite nice for what they sell for.
