My bass has recently started distorting and I'm not sure what may have caused the problem, but I think it might be the electronics in the bass itself. The distortion only occurs when I really dig in (I tend to play very aggressively with my pick and fingers on our heavier songs) but if I stick to a light touch it sounds fine. When I say light touch I am referring to a lighter touch than a normal finger picking touch so playing like this all the time would be an inconvenience. I haven't had the chance to try another bass due to them being at home and me being at college. I don't remember having any trouble like this before and that's why I'm stumped. I play with the tone and volume on the bass all the way up in passive mode. Having the bass in series or parallel does not make a difference along with having either pickup soloed or both on. I switched out the pickups around 2 years ago with DiMarzio model J pickups. I was thinking it might be the pickup height considering the bridge pickup is a little high, but this was never a problem before and I still get distortion even with that pickup off. Would the output jack have anything to do with this because it sometimes crackles a bit when the cord is wiggled, maybe just a bad connection? My bass has also cut out completely on one occasion for around a minute and after checking all the connections (minus the output jack on the bass) and whatnot I still couldn't find the problem but it soon kicked back on and has never done it again. I have also tried different cords to no avail. I have tried another cab with the same amp and still ending with the same result. I am using a Hartke LH1000 with a 410 HX cab (I have 2 but only use 1 at a time unless at big shows.) The amp blew before at my first practice and Larry was kind enough to get that taken care of so it was recently fixed (about a year ago which I say is pretty recent considering the insides were replaced and shouldn't be going bad already.) The tube had also gone bad in it so that was replaced a few months ago.The volume stays around 4 and has never needed to get to 6 except maybe once or twice which still seems like a medium volume level. The preamp is set to 4-bass 10-mid 5-treble because of the mids being cut-only and the others being mostly boost on the LH1000. Messing with the preamp didn't seem to help eliminate the distortion at all. It doesn't sound terrible but I want a clean sound and having random bad luck when it comes to gear, or anything else that involves electricity for that matter, has got me paranoid that that something bad might be happening again. Sorry if this is in the wrong thread, but I think it might be the bass over the amp or cab. Any suggestions would be greatly appreciated.
