NooooO!!!! Q-Tron died!!!!!!

Happynoj · #1 09-07-2008, 05:09 AM

Help me! My micro Q-Tron has died! I haven't played with it for about 3 or 4 weeks due to holidays, work, etc, and I came back to it today and it isn't working

When I turn it on with the switch nothing happens - no sound, no lights, nothing...

I don't use batteries, the power supply appears to be working (it powers other pedals), my daisy chain seems to be functional. I took the back off but I couldn't see any fried components.

WHAT IS WRONG?! WHAT CAN I DO ABOUT IT??!!!

sorry to hear that i remember you telling me that q-tron being on of your favorites but maybe now you got a good reason to get a couple of more filters :P

True...

The Prometheus clips were very tempting....

OTOH, If I'm shelling out £60 for a pedal, I don't expect it to break within 6 months...

yeah i understand. actually i have never really heard of a analogue pedal just going dead. maybe it might just *pop* start working when you plug in tomorrow?

Have you checked for loose solder joints at the switch? IME, some of the EHX pedals I've owned did the same thing as your Micro Q and that was the culprit. Hope this helps.

Good suggestion - I'll check it out.

Do you get clean tone with the Qtron on or off at all, or does absolutely nothing make it through at anytime?

Happynoj · #8 09-09-2008, 04:26 AM

I get clean tone when the effect is turned off. As soon as I turn it on there is nothing at all - the bypass light doesn't even turn on.

Have you tried it with a battery? That might tell you if the problem is at your power jack.

Happynoj · #10 09-10-2008, 06:22 AM

Well, I checked for loose/dry solder, couldn't see any.

Then, I tried a battery - it lives! I don't believe I didn't think of that before. I must have been having a really bad day

Looks like the problem is with the power. However, I am sure it is not the power supply - I tried two different power supplies and neither worked. I then tried the power supplies with other pedals, and they both appear to be working perfectly.

Therefore I conclude that it must be a problem with how the electricity is getting inside the pedal - damned devil magjik!!! What could the problem be? The joint between the power jack and the board seems to be fine, the centre pin is intact and doesn't seem to be bent -what else should I look for?

Thanks guys - you have helped me so much already!

I would guess that there is a problem inside the jack, or that the solder points are un-good. The problem with the XO series is that it is really hard to do any work or inspection on the guts with such small components. I wish I had further suggestions for you, but at this point I would be scratching my head for solutions as well.

my advice: get a qtron+. tried both and the + really beat the micro. less hum and meatier sounds.

smakbass · #13 09-10-2008, 07:22 AM

My qtron plus died a few years back, the chips all fried out....had a guy fix it and he rebuilt it using better components sounds way better now.

sk8 · #14 09-10-2008, 08:02 AM

if its less than 6 months old send it back under warranty
