Q-Tron fix

[N64Lover]

Is anyone on here capable of fixing my EHX Q-Tron pedal? I took it to bits a while ago to rehouse it, and have since lost the gut shots I took as a reference and the will to complete this project. I am am looking for someone that could put it back together, mod it for true bypass and possibly rehouse it in a small enclosure. If anyone can help that would be great.

for the effort (& postage) involved in your project, it may pay off to just buy another filter ? i know that sounds harsh. repair should be cheaper, but may not prove to be ..

Are you sure about the true bypass mod? That's a 24 volt pedal and has arguably a very high quality buffer in there. If I kept only one 'buffer' stage on my current board then it would be this one.

Thats interesting to hear.
I found mine to really suck the tone when not on, didn't like it, so I bypass modded mine. I also added a level control to tame some of the volume spikes & swapped out the red LED for green one, wired up to indicate when the effect is actually on.
Reminds me, I've got to get a matching EHX knob for the new control.

Let me know if you find one, as I'm about to put a volume control on the output stage of my Q-tron +.

I've found them [url="http://www.banzaimusic.com/EH-knob-current-design-push-on.html"]here[/url]. I've also got to order some 1meg log reverse pots for some 'SFT' clones I'm building, from Banzai - only place I can find them. If you want me to order an extra EHX knob, let me know (save you postage). Will probably put order inthis weekend.

That'd be great, as I'm hoping to do my mod this weekend also. Will PM you details etc...

@ nick

Did you do these mods just from your own knowledge or did you follow a guide? Ive just purchased a q-tron plus, and a true bypass and on/off LED would compliment it nicely. its an awesome pedal

I did volume mod from [url="http://www.diystompboxes.com/smfforum/index.php?topic=7354.0"]DIY Stomboxes thread : Qtron volume fix[/url] & used a 10k log pot.
The others just from knowledge I guess. However, I understand that some Qtrons are actually true bypass(?), so it could be worth checking.

Though, some folk think that running a limiter after it, is more effective.

can someone enlighten me on the volume mod, where I can get the parts and a drawing? cheers.
