Advice Needed Please

kevjones

I have a few obscure questions that some of you clever oakes can help me with.

1. Can an AMP (Fender Hot Rod Deluxe III) blow the tone caps in a guitar.
2. If so how and why is it doing this.
3. What can cause a "light shock" when plugging into the amp. How can current be getting onto my pickups.
4. Why when my Fender is switched on does it cause a Mic to shock (no the mic is nowhere near the Fender) the only thing they have in common is a multi plug adapter. I switch the Fender off and the shocking goes away.
5. Where is the best place in north joburg to take the amp for a check over.

Any ideas. (yip I will take the amp in)

Thanks guys.

I'm gonna reply quickly and say that you may have a grounding problem in the amp. I'd advise you not to keep using that amp. Sometimes the shocks can be bad or, even worse, fatal. I'd advise taking it in as soon as you can but not sure where. (someone will know)

Ja thanks choclit I am just a little nuts bud but not completely insane ha ha ha ha . I have not used it since I felt the first tinge so no problems there. I suspect the same thing but thought let me just ask here in case someone who knows the kit says " hey man thats normal the guitar cable is faulty " or something like that ha ha ha ha.

Not really obscure. Good questions. ?

1. Can an AMP (Fender Hot Rod Deluxe III) blow the tone caps in a guitar.

Highly unlikely, but if it does, it's extremely serious - it takes at least a few hundred volts to blow a cap.

3. What can cause a "light shock" when plugging into the amp. How can current be getting onto my pickups.
4. Why when my Fender is switched on does it cause a Mic to shock

It's an earthing problem, plus maybe another fault. The amp isn't earthed properly (does it have a three pin plug on it and is it wired correctly?) and when it connects to something else that is earthed (in this case you - via the strings to a mic connected to a PA that is earthed), it uses that path to dump any excess voltage to ground. There shouldn't be any serious voltage on the ground anyway, so that's why I say there might be another fault too.

Check the obvious ground connections - the lead and plug, but take the amp in to be checked out anyway - http://www.guitarforum.co.za/amps-speakers-and-valves/amp-techs/

Ja thanks Alan checked all the obvious things and cant see anything that stands out. I have got hold of JP and waiting for him to come back to me with a reply on time, place etc to drop the Amp off.

Quick update. The Tone controls on the Gibson were not working due to a faulty guitar cable. Annoys me because I have just had the cables re-done. Obviously a fault in the cable itself. So that takes care of the Gibson it's working great. The Amp goes to JP to check the grounding for me and the mixer goes to Marshall in the morning. So making progress.
