Dang, I definitely don't have that ability. But it's great that you guys figured it out. Maybe I'd just send it to a local technician to fix.

After some inspection I can say - it is even easier than expected. A component needs to be removed to get the filter working correctly. I will post a step by step instruction on that. You will not need any soldering. You need a box cutter and steady hands. :D

-Like cutting traces on the board?
-if soldering/desoldering would be better please advise - i'll be standing by to hear how you engineer this.

No, you cut the pins of a component. You can see what part has to be removed. If you come to the conclusion desoldering is the better way just go for it on your own risk. But even I prefer cutting the pins as it is faster, cleaner and safer.

More good news! Year 5 with the spectralis and it just keeps on giving.

I've generally stayed away from the 24db except for some deep filtered sounds. This is exciting news!

NO WAY!!!!!!!!!! This is so awesome.

What a good day.

Just finished renovating my bathroom (new toilet, new vanity/sink, new flooring, fixed the walls, etc), bought a canon 5D2, and now this. Oh, and it's "President's day" in the US, so we get the day off, whoop!

I am still working on the explanation and video. That will take a little time as I am busy with a lot of things but I really enjoyed playing my old tracks with the corrected sounds again.

Is this a common problem of all Spectralii, or is it all Spectralis 2, or from build model no. XXXX to XXXX?
