M-80 Trouble

[one]

I have had a MXR m-80 for about 6 month now and love the pedal. However yesterday when playing throught it, as i always do, i started to get this horrible buzzing/feedback sound in the background. Well i lie, it's not even background feedback, it's very loud and has random attacks of more feedback and not forgetting this pedal is silent normally and lets nothing through it.

However i can't get into the pedal either as it has those special allen key type nuts in there so am unable to get into it. I too don't have the receipt either so am unable to take it back. Has anyone else experienced this and what do i have to do to solve the problem?

Thanks all,

Nope, but could you post an example of what's happening?

I'm not quite sure what sound you're getting.

running on power supply or batteries?

Now would be an excellent opportunity to go buy a set of allen wrenches. They're cheap, and worth having in the toolbox. Just be sure to get both metric and "English" sets.

Running on a power bank which also isn't being overloaded. I'll go buy a set of them when i get the chance this week and check it out. I've found the recipe for it though, so if i find no obvious problem i'll take it back.

Overload isn't the only fault condition; EMI could be getting in via the power supply or signal cables.

Try running it on batterys to see if the fault re-occurs. It'll help the elimination process.
