I ordered these strings for my secondary bass, a Squier Affinity PJ Bass. On my main bass I have the Rotosound SH77 Steve Harris Signature strings. The Ernie Ball strings sound good and the quality is fine. However, the surface seems to less smooth than on the Rotosound strings. The Rotos cost only 2€ more, but are imho better sounding and are of better quality. Nonetheless, I can still recommend the Ernie Ball strings, if you can deal with them being a bit rougher.
