Shocking Amplifier?

[AllenBass7]

Also had a Guild ThunderbassII amp (so glad to be rid of that deathtrap). Singer in my band was using it for gtr...he didn't even touch the mic, rather he claims he saw a blue arc coming at him. I didn't see it happen, but heard the ZAP! Took him a few days to calm down.

Whoa... anybody up for some acoustic?

Now I am concerned. My sunn concert bass head (late 70's) has a 2 prong plug. Do you suggest I get a tech to replace it? Its never shocked me, but it does hum a bit.

yes you should do that although it is a really easy job to do

Yes, and have him install bypass caps and MOVs in a delta configuration while he's in there. If he doesn't know what that means find someone else. The hum is just as likely caused by old dried out power supply caps, so while it's open you should replace them, upgrading their capacity. Generally it costs at least an hour's labor just to open the box up, so take advantage of it while he's in there.
