My Original Mu-tron III is not OK

[CallMeBlind]

It was working just like it should before the moment when I took it to rehearsal place, then sound became too boomy, I thought maybe the batteries died, I came home and yes, batteries where dead. I went to the shop and bought 2 Duracell batteries, best I could find, I changed them, switched on Mu-tron and nothing, I could hear the clean sound but no effect at all. I decided to take pedal apart to see if I burned it, it looked ok, I plugged my bass while the pedal was opened and it worked again, I almost believed it is fixed and put it together, sound became boomy again. I took the pedal apart one more time and since that no effect at all, however clean sound could be heard.
What could it be?

Short from the power.board to the case?

well I don't know if that helps.. but when I received mine (it has an adapter), I actually forgot to power it, but clean sound was still coming out of it... I was ready to phone the guy who sold it to me until I realised it, it took me a good 20 minutes

if you have a power supply input, try to buy one? mine is one of these: Invalid Link Removed

I think the 5-12, but I need to check when I'm home first, let me know if you need the info

Send it to L-sound

 

[Lebowsky]

does L-sound do repair for Europe? didn't seem so on their page. actually I sent him an e-mail a while ago I now realize I have never received an answer

 

[CallMeBlind]

Yes, I think I want an adapter, doesn't metter if pedal is broken or not, I don't want to bother with batteries, or maybe mod it with boss style power input. I found one german web-site for mods and repairs Invalid Link Removed They also do true bypass.

If you're looking for someone to mod your Mu-tron for 9v standard Boss input, I highly recommend Dave at the GigRig.

Go to Invalid Link Removed and email Dave with what you want done. He did mine for me and the work was top quality! I couldn't be happier.

very interesting Higgie and CallMeBlind. does Dave at GigRig also do true-bypass?
