Ok so I connect my bass to a direct box and next to a preamp that goes to an interface. I notice a kinda click sound every now and then so I think well maibe a bad cable. I change the bass cable dosnt seem to solve the problem. now i try conecting the trhu of the direct box to the amp and I can hear the click noise on the amp. Now Ill try to plug the bass directly to the bass amp to see if the noise is still there. The noise is still there but much much quiet to hear it I need to boost the mid and high frecuencies. But its still there . can anyone tell me where that noise comes from and how to solve it pd I also tried to lif the ground from the direct box but it just makes the noise louder .. thanks :?
