While I"m sure there are a few jokes in that title ... ... the little string on my new-to-me NS CR4M "puts-out" ... ... noticeably less volume, all the way up the neck. It is most apparent in the piezo mode, but also noticeably in the mag' p'up mode .. so I'm thinking it must be an amp-response thing. The other strings are a a lot fuller, and a bit boomy if I run the bass knobs up too high. I have a few good - old school e-bass guit' amps units, like an AMP, but they're not here right now, so I'm currently using a Fender Princeton through an EA VL208. This is all loud'ish living room pizzicato until I get enough courage to play it in more public places ... but in the meantime: It could be a symptom of old strings (I bought it used), or something else, but do ya think the Princeton amp can be the cause of ALL the tonal inconsistencies, or should I look elsewhere? I just remembered there is an L2 (LAB Series) head in the garage - that should be tried before posting this, I guess, but it's too late now!
