funkyjimbob Posted October 18, 2015 Share Posted October 18, 2015 Hi! Whilst setting up at a gig last night I noticed no power was showing for any of the effects on my pedalboard although the power supply was showing power. After investigation it would seem that when my Aguilar Octamizer pedal is introduced into the power supply, it kills the power to every other pedal. It is not in a daisy chain and is connected via a 9v input into my PSU via it's own socket. As soon as it is removed from the PSU all the other pedals have power again. I have tried the pedal on its own and it still does not draw any power and the led does not come on. Knowing very little about these things I am asking if anyone knows what may have happened or if my pedal is repairable? I'm a bit gutted as it's a reasonably pricey pedal and I only bought it last month on here! Thanks Quote Link to comment Share on other sites More sharing options...
Norris Posted October 18, 2015 Share Posted October 18, 2015 Have you got the + & - the right way round? Quote Link to comment Share on other sites More sharing options...

[/quote] Please excuse my stupidity but I don't know what that means... When it comes to pedals and whatnot I'm literally useless. How would I check this?

Norris Posted October 18, 2015 Share Posted October 18, 2015 Your power supply lead has two contacts - the bit on the outside and the inner bit. One of these will be positive and the other negative, just like on a battery. When it comes to pedals there is no standard as to whether the middle bit should be positive or the outer bit. They can differ. Usually your power supply will have a "polarity" switch, or you can somehow switch the cable round. Look at your pedal and there should be a diagram either next to the power socket or printed on the label, that should tell you which way round the power should go. I'm guessing here that maybe the pedal that is giving you problems needs the power the other way round to your other pedals Quote Link to comment Share on other sites More sharing options...
funkyjimbob Posted October 18, 2015 Author Share Posted October 18, 2015 Thanks for the help. I just gave the pedal a try as you suggested and still nothing. I also tried with a battery and still have nothing. Is this likely fried? Quote Link to comment Share on other sites More sharing options...
Norris Posted October 18, 2015 Share Posted October 18, 2015 Possibly. Have you tried the pedal on it's own with a battery in it? Quote Link to comment Share on other sites More sharing options...
funkyjimbob Posted October 18, 2015 Author Share Posted October 18, 2015 Yes. Nothing at all. Quote Link to comment Share on other sites More sharing options...
Norris Posted October 19, 2015 Share Posted October 19, 2015 Sounds like it's broken then. I'd still check the polarity on the pedal as there is a fair chance that you might have blown it by accidentally connecting the power the wrong way round (and avoid repeating it if/when you get it repaired). If that is the case, hopefully it should be relatively easy to repair. I'd find a local electronics repair guy to take a look at it. Your local music shops might be a good place to start Quote Link to comment Share on other sites More sharing options...
Billy Apple Posted October 19, 2015 Share Posted October 19, 2015 Who is Aguilars UK distributor? They might have an authorized servicer. Quote Link to comment Share on other sites More sharing options...
funkyjimbob Posted October 19, 2015 Author Share Posted October 19, 2015 Great thanks. I think what you said has happened for sure as I had a bit of a mare with my pedal board on Saturday night. I'll try and find someone local who does pedal repairs. Quote Link to comment Share on other sites More sharing options...
Norris Posted October 19, 2015 Share Posted October 19, 2015 There should be some indication of polarity like on the attached picture. In this case the centre contact should be the negative supply. Quote Link to comment Share on other sites More sharing options...
Matt P Posted October 19, 2015 Share Posted October 19, 2015 the aggie has the same polarity as the Boss standard, I'm running mine from a cheap Harley Benton supply with no issues, it sounds like this one has died, hopefully you can find someone local to take a look, I know a guy I the Newcastle area if you're local.

funkyjimbob Posted October 19, 2015 Author Share Posted October 19, 2015 If that's the case Mapp then yeah it must have died somehow. HEre is my power supply and seems to be the same as the polarity on the pedal?

adamg67 Posted October 21, 2015 Share Posted October 21, 2015 It should be pretty easy to work out if it's anything to do with polarity or if that's a red herring: If the pedal worked fine, you didn't rewire anything and then it stopped working, it's nothing to do with polarity.
