Recently I have been having some problems with my bass. A warwick FNA Jazzman. It has active pickups so it has a switched jack. It would cut out for no apparent reason after I had been playing for a long time, like an hour or two. So usually at a gig. I replaced the battery and even had a new jack installed. I still had the same problem. Then I talked to a guitar tech guru. He told me that it was the cable I was using. I used to use the planet waves standard instrument cables with the compressions springs that "lock" the cable into your input jack. He told me that non-switchcraft type 1/4" jacks should not be used on switched input jacks(active). If you hold up a standard 1/4" switchcraft jack and a non-switchcraft jack(usually made in asia) like the planet waves cables you can see that the tips are different. He said that this along with the compression springs on the planet waves cables are probably what are causing my problems. Since it takes awhile for this problem to occur I'll let everyone know if the guitar tech was correct or if it was just bs.
