Hi! All right, here's the deal. I bought my bass (Yamaha RBX270) and my amp (Hartke B60) two weeks ago. I'm a true newbie to the bass and to music in general. Over the past week and a half I've built up a 'library' of sorts: Talk Bass (Heh, in case you don't know how you got here, or something ) BASSLOBSTER CyberFretBass.com mpc Bass Libster (My Bible.) Cleaning up right and left hand technique (By Adam Nitti.) The Right Way to Install Strings (By Scott Malandrone & Jim Roberts) Electricbass.com Fretting-hand technique (By Adam Nitti.) ActiveBass Introduction to Scale and Chord theory (By Jazzbo) Granted, I haven't read all of these sites too thoroughly, but they seem like excellent resources. Hope some of my fellow newbies find this useful! Feel free to add sites that are not on my list (actually, I'm looking for a site which describes all the 'tech-speak', i.e. slap'n'pop, ghost note, double thumbing, etc. etc.)! Now, a question for the veterans. As I mentioned earlier I own a Yamaha RBX270 bass, and I have a little problem (or is it a problem, I'm not sure). When I pluck the open A string, I get this annoying 'ringing' sound. I'm pretty sure it's not supposed to be there. It's not too loud, but it's just loud enough to notice it's there. At first when I had my bass plugged into the amp, I thought it might just be the pick-ups being too close to the strings. I turned my amp off, and the ringing was still there. Any idea what the problem is? Thanks!
