I looked at those Rotosound strings, you are right, they use the core end consept like the piano.
Alembic says theye electronic give a greater natural sound.
The thing is, I hear that Stanley C. uses those same strings, but I do no want that sound (I really want lots of tones, and a vibrating sound)
I was going for a medium or a long scale, but if 36 inches could help me get a rich, bright, sustained sound, with no buzz, BUT STILL HAVE A EXTREME LOW ACTION... (I like the action to be unbelivably low, but hate what big string nazal sound.)
Hope I finaly found that dream sound...
Still hope to get a Pro's opinion. After all, YOU will make that bass.
