Hi, I've just got an Aria Pro II CSB 300 bass. Beautiful, sweet neck, extremely comfy and lovely tone. It seems to have been sleeping for quite a few years, but it's in pretty good nick for a 30 year old bass. Only problem is, whenever i strum or pull (hard) two notes simultaneously, the bass produces an awful noise, kind of like a distortion, but not a distorted bass sound, just the distortion without the bass sound. Yeah, the sound of the bass disappears for a moment and I get this loud crackly noise, similar to a jack plugging with the gain high but a bit higher in frequency. Sometimes I also experience pops and glitches on single low notes, especially when I hit the string with the nail (I play flamenco guitar as well, so, I have some nails. Tried different leads, amps, etc, and it's all the same, which leads me to think that there's something wrong either with the pickup or the wiring. I paid really little money for the bass, so I don't mind to spend up to 100 bucks or a bit more to get it in shape. I have an mp3 to show the sound, but I don't know how to post it! I'd appreciate any feedback/advice as to what's going on, since I don't know much about pickups and electronics. Also, in case I have to change the pickup (I hope not), any ideas of replacements for this model? Thank you!
