I use solos, but tuned normal, to pull a big pizz sound it is a lot more like gut, you dig in the same way.
Pretty spot on. I will add that switching over to steels, and then solos, has introduced me to a world I had previously shunned as a gut-only player. The main difference has been string height and tension but also recorded sounds. Once I put on a set of solos and really started attacking solo playing I quickly realized the advantages. My italian bass loved the higher tension and the higher tension forced me to lower the string height to a level I would never have been comfortable with as a percussive slap inclined player. With a new sense of, gasp, sustain, I started to explore longer notes. The more sustain forced me to be more in tune, I actually could not get away with the same intonation variables that I could with gut. The sound almost felt as though it were coming out of a different place on the bass, i.e. much further down. It also set in a different place in the mix, less 'around' the other instruments and more 'inside'. There was a time I would have hated this as I wanted the bass to be drum-like. That works great for a lot of music but not all. I quickly determined years ago, I think when I actually took off my guts, that irish music did not sound good with guts. It just didn't sit where I needed it to and was not doing the job as well as steel. I remember saying that bass in irish music needed to come up from the bottom as if the bottom of the pool was raised and formerly swimming instruments could suddenly stand on terra firma. Steel comes up from beneath. Gut comes more surround sound. I love both for different applications. The new super low action has allowed me to comfortably tackle the cello suites and make me finally more comfortable in the upper registers. Some may not need that help but I certainly did. I also find that recording with solos and a good mic creates a crystal clear note that my engineers really dig. The tighter string pushes the air along and the solo tuning creates a clarity I've never had before. I've even experimented a little with Ray Browns "full side length of the finger" technique. All very illuminating.
