There are checklists there for troubleshooting Strats and other guitars, and you could probably use one of those to see if your bass has a problem with one or both pickups, needs shielding, etc. http://www.guitarnuts.com/index.php
What make/model is it, and what's in it for pickups? (I still don't know a J-Bass from a P-Bass, but I know where to look them up. :wink: )
EDIT: Forgot to mention that it could be something with the household wiring in general. Even if there's not much you can do with that short of calling in an electrician, you can still shield the axe so that the noise can't get into it. Once you're getting just signal (no noise) out of your sound system, you can crank it up more. 8)]]> Guitar Repair and Maintenance Doug_C https://guitarnoise.forum/guitar-repair-and-maintenance/weird-humming-pulse-from-bass-guitar/#post-189676 https://guitarnoise.forum/guitar-repair-and-maintenance/weird-humming-pulse-from-bass-guitar/#post-189633 Mon, 17 Jul 2006 10:15:30 +0000 Guitar Repair and Maintenance Crims0n https://guitarnoise.forum/guitar-repair-and-maintenance/weird-humming-pulse-from-bass-guitar/#post-189633 https://guitarnoise.forum/guitar-repair-and-maintenance/weird-humming-pulse-from-bass-guitar/#post-187549 Tue, 04 Jul 2006 23:12:34 +0000
High quality capacitors look like a Chicklette (the chewing gum).]]> Guitar Repair and Maintenance PRNDL https://guitarnoise.forum/guitar-repair-and-maintenance/weird-humming-pulse-from-bass-guitar/#post-187549 https://guitarnoise.forum/guitar-repair-and-maintenance/weird-humming-pulse-from-bass-guitar/#post-18925 Tue, 04 Jul 2006 11:51:35 +0000 I'm having a problem with my bass guitar. I get a weird humming/drone sound which is not constant but a 'pulsing' effect. It happens sometimes straight away or within about 20mins of switching my amp on. It's affected by the tone control and the volume on my bass, but my bass still works (though the hum is quite loud, makes it impossible to play).
I've tried bass with different amps and leads - still happens, though not tried a different bass. I've searched for previous posts about the whole electricity/transformer issue. I don't have any phone chargers or anything in my room and the hum still happens in other rooms in the house. Not tried switching off the main circuit breaker yet, but in the meantime has anyone got any ideas?
