Hello and good day to all of you! I guess it's time for me to break my 'lurk' status and post cause these knobs on my bass are driving me nuts. For the record, I own an Ibanez GSR205 bass and at the moment, it really does suit my needs. I need to know how to 'play' around with the knobs on my bass and after doing a bit of research around here and on the net, I have come to a conclusion that these four knbos each represents: bass boost(is it some sort of marketing gimmick?), treble, bridge pickup volume and neck pickup volume. Am I even close or what? Of course my bass isnt as sophiscated as many of yours but I'm sure all of you are a lot more knowledgeable on these things. Oh, for the record, my bass didnt come with a manual and this is my 2nd bass ever after playing for about 4 years. I know.. I know... It probably doesnt exist unless it has pics and here they are! As you may have guessed right, I like my bass a little bit too much.
