Hi guys, I really hope this isn't what I think it is but

this pains me...
I got to rehearsal today and I plug my adapter into my effects. Basically, Micro Q-Tron practically won't power on (has battery in it and that works fine, but then when power adapter gets plugged in the light pulses on momentarily then goes out), Boss OC-2 now has oddly a slightly dim light (this might be my imagination, but I swear it was a little brighter than that before)...and my LS-2 wasn't functioning at all but strangely that seems to be working properly now.
The pedals are powered using a power adapter into the LS-2 and daisy chains into the others - I have not sound tested them yet but will do tomorrow, however the lights thing is obviously very distressing. The Micro Q Tron I would be a little annoyed about but I could save up for another one, LS2 same (I love that pedal so much though) the OC-2 however was a gift from my girlfriend quite a while ago and would be bloody sore if that either gave way or I had to stop using it (plus they are pretty much strictly eBay purchases now in lieu of OC-3).
Any light shed on this would be greatly appreciated - tried a different power adapter, tried different wall warts, even had the opportunity to try different power in different house but all the same conclusion. Huge thanks!!
