Ok im a tad confused, my pedal rig was setup in the following order: my metal muff into my doctor Q to my small stone (both classic versions) running into my marshall supervibe, and finally my boss DD7, the boss, marshall and metal muff are all centre negative, and I was obviously using the 1spot vintage adaptors for the stone and the Q, as I mentioned in my first post the setup was not working, but also the LED’s were lighting up, and a very small amount of charge was coming through the pedal casings. I have actually proceeded to purchase 1spot polarity converter assuming I would need to put them in front of the vintage adaptors, however mentioned in this thread the vintage adaptors already reverse polarity, so have any of you guys got any idea as to why my rig is not working is it the digital boss being in the setup or do I need to have a separate 1spot for these reverse polarity pedals, I was getting the assumption from mr.grim that he runs many of pedals occasionally of a 1spot, im guessing including of both polarity, please help me with these queries friends
It’s either that a pedal has positive ground and doesn’t want to be daisied, or that a pedal is broken.
the stone and the Q centre postive the rest are negative, so I guess they dont want to be daisied with different polarities, the stone works 100% on its own however I think my Doctor Q is broken, in fact I think it may of been broken long ago, I thought it was a dying battery, however the LED was very bright, the pedals was sound pretty uneffective, and the range knob was doing virtually nothing, however the bass switch had an effect, now using an adaptor it is doing the same thing, either I’ve put the final nail in the coffin or it was already broken, Tbh not a favourite pedal of mine but still a pain in the arse if its broken.

What kind of audio cables are you using?
2 custom made terminators with neutrik ends, they are quite short, and then in between some small patch cables, one is a warick. As I said before not only was I not recieving signal, but a small amount charge was coming through the casing and other metal parts on my pedals.

Usually, there will be something like a diode, a series resistor/parallel capacitor acting as a filter, maybe a zener, whatever. Sometimes those will get burnt very badly, but the pedal will still work, especially if the part was in parallel. I had a Pigtronix Philosopher’s Tone that had the wrong adaptor plugged in, and it smoked a series resistor. Of course the pedal didn’t work until that resistor was replaced. But if you are getting a signal through, and you don’t smell anything, you are likely OK. Just on the off chance you took out a parallel diode or something, check anyway.you know what Im such a noob I realised all of my pedals except for the stone and the Q which Im unsre of, are centre negative polarity, same as the 1spot, so I have no idea why nothing is working, with the 1spot, do you know if the classic Doctor Q and small stone are centre negative polairty? I have no problem with opening up pedals, I do plenty of work and overhauls on guitars, Im just ignorant and dont pay attention to small but important details. However now im confussed as to why my pedals would not work with the 1spot, other than the Q and the stone possibly being reverse pol?
Maiden Metal MuffMemberQuote:yeah i have the full version of the metal muff with top boost, and i use it with no problems at all, pedal shows center negative like the 1Spotsorry I was wrong about the polarity, I was rying to use my 1 spot with my full version Metal muff, Doctor q, Small stone, Marshall Supervibe, Boss DD7, however no sound was coming, and a little amount of shock was coming off the pedals, Im a pretty confused, any ideas about what is wrong?
Maiden Metal MuffMemberQuote:to both of you: i dont see any reason why the Brick shouldent work for the effect unit, so perhaps its a problem with your power jack, and i have and use 3 1Spot adapters on my board and i never have an issue with my Metal Muff, it should be the same polarity.So you have the 1spot connected up straight into the pedal without a converter? that’s weird becasue the polarity symbol on the 1spot is opposite to that of the metal muff. The power jack on my muff works fine because I use it with my marshall adaptor when I use it alone.
Maiden Metal MuffMemberTotal coincidence I’ve got a metal muff, and literally an hour ago, in a similar noob act I used the incorrect power supply, EH pedals like the metal muff have reverse polarity I used a 1 spot without the converter and the light came on but no sound, the pedal works when I use my marshall supply however im worried there could be some damage, im guessing the dunlop brick has the opposite polarity to that of the M muff so it would not work.
