On the advice of several TBers, I got an order of 1/4" monoprice cables. They cheap as heck, look and feel great, heavy duty plugs, thick sturdy cable, etc. They sound fine with my active basses. But... With passive basses or with my active basses in passive mode, the cable is horribly unusably microphonic. As in, tapping on the cable sounds like tapping directoly on the bass strings. What the heck??? Did I get a bad batch??? I got some straight plugs, some right angles, so they weren't all identical. But it seems they are all microphonic with passive basses. Is this just the hidden cost of cheap cabling? Should I demand my money back, exchange, or...?
