well i pick up my second bass today. i've been playing for a few months now and i have been getting a lot better every day. still a lot to learn though. well i am still pretty new to guitars and basses. i am curoise, on the t-bird i notice it has three knobs. i have no idea what each one does.i was assuming one was volume and the other two were tone, but it seems they all effect volume and ton. i am just use to my old bass and it just has the tone and volume knobs. i feel stupid asking this question but hey got to figure it out some how.
