Not sure if my amp is broken just got it back from repairer and i plugged it in playin away and it was fine. THen it started humming so i switched it off. Told dad it was broken..cause he drives it everywhere i still pay for everything. He wanted to see i said it was not a good idea turned it on the amp lit up like fireworks for a second. Switched her off dad said he didnt see i warned him tunred it back on and it starting squealing with all eq and volume on 0. I then realized that i had a bigger power supply in my amp then required amp needs 240v i had 250v plug in..... am i ****ed or can i go buy a new 240v plug and it will work?

yes yes i do know that after anything like hum i shoudnt of touched it let alone turned it on. im a fool

thanks

The fact that you used 250V on the 240V amp shouldn't be the problem, the voltage in the outlet is never perfect and it has a swing of something like 10 volts anyways. Your problem is definitely elsewhere.

Maybe it's your guitar.



is that srsly possible cause if it is. i have 2 guitars one i just got 3 days ago Schecter blackjack atx and an epi lp zakwylde which is old.

so the amp is a marshall jcm900 dual reverb 4100 this is how i have the amp connected to my cab 4x12 jcm900 1960b.


amp impedence set at 16 next to the 16 it has (4)

speaker setting is on mono and the lead plugs into the 16 input.
this is correct?

thanks for the speedy replies.

And more. Stuff made for UK's 220V works perfectly well on our 240V. They don't make special ones for our market, they just chuck on a different plug.

I don't know much about gear. But if your amp sounds horrible with BOTH of those guitars, then it means that most probably your amp is the problem, in rare cases it's the guitars.

no no no sorry the amp arced on the inside when i switched it on without a lead in it so i switched her off.. and switched her back on and it was squealin like a banshee with no lead. So i shld take it back to the repair guy then.

make sure you get a either a refund for the previous repair or your next repair for free.

The amp ARCED? Wow, many things could have gone wrong in that case. I wouldn't be surprised if you blew your power transformer and if it also took out a bunch of other components in your power supply. Take it to a tech because it sounds like you have a big problem if something actually arced in the amp.

Sorry to semi-derail, but are you saying that I could buy a 220V amp from the UK with a UK plug, and use a simple $10 plug converter to power it and it will work fine?

Appologies for the ignorance but what do you mean by the amp 'arced'?

You CAN play anything with anything....but some guitars sound right for some things, and not for others. Single coils sound retarded for metal, though those who are apeshit about harpsichord probably beg to differ.

Here's a quick tip, if your amp lights up like it's putting on a showcase of fireworks it's time to bring it to a tech.

Or turn the volume to 11, retreat to a safe distance and go crazy!!!


If you just got your amp back from the repair shop, you should really always make them turn it on and play it in front of you before you give them your money.
I have a huge fear if rays.
