Is there any good replacement pick-ups for Gibson Thunderbird? I played my T-bird in a music store(I was test driving the Mesa 400+), and there was annoying extra noise, coming out of the amp. I asked about it, and the seller said that T-birds pick-ups are not the best quality, and pick up interference from the room lights in the store. I was amazed, but when I tried with another bass, there wasn´t that noise anymore. Anyone experienced this? Or replaced the pups of the T-bird?
