Yesterday I got my first bass guitar, a SX FPB62+/FR, along with a 10W VOX practice amp and cable -- of course. I played with it a bit yesterday, learning on it. Everything seemed fine, until I took it out to practice further today. I was playing a bass line -- from an exercise on the Instructional DVD, that came with the bass guitar, that's when I notice when I was plucking the G string that it was buzzing out loudly in a kind of distorted manner. The distortion was turned off on the amp and the the treble and bass selections on the amp was on zero -- the volume was half way on 5. I then noticed that if I played certain notes, it did exactly the same as on the G string. One of the notes was on the third fret of the A string. My finger was placed correctly just behind the third fret -- I know this as I also play the acoustic guitar. This is the first time using an amp and an electric bass guitar. Am I doing something wrong or is my amp or bass guitar faulty?. I would really appreciate your assistance on this matter. Oh, I bought the Bass and Amp from the local guitar shop where I usually go to, when I tested the bass out in the shop (just plucking the strings a couple of times) and it was working okay and I took extreme care when traveling home with it and moving it around. When turning one of the knobs on the bass -- it also made a scratching sound.
