I didn't mean to cause a ruckus. I didn't return in time to see the pulled reply. However I did get a set of urethane strings from Bufo Bass strings. They are better in some ways and worse others.
Pros -
a little stiffer
slicker
I haven't broken a G string yet.
Cons
they vibrate differently and are inconsistent in volume from string to sting. The A & D strings are louder than the E & G strings. The Piezo pickup really responds better when the strings vibrate more.
The slicker string is harder to tie in a tight knot, so they slip and don't stay in tune as well. I'm sure that issue can be resolved with a little bit of Southern Strategy.
The Asbory is such a great bass no matter what string is on it. It just works, and the sound is always large. Other players can't believe how big it sounds and how much like an upright bass it's space is. I have taken mine and mounted it to a small, kids style Strat like body and it is way easier to hold and to play. I can take my hands off of the bass and it stays in place instead of taking the neck dive. I love this Bass.
