Build Your Own Clone Message Board

Finished my analog vibrato and seems to all be functioning fine. The vibrato sounds incredible. However I'm getting some very significant high end loss when engaging the effect. Is this normal? I tried using a buffer in front of it too with no luck.
Thoughts/suggestions?

I would not say "very significant" high end loss is normal, although that kind of thing can be somewhat subjective.

We'd be glad to try and help if we can see your work. Could you please post photos of your build, including both sides of the board? Make sure they're clearly in focus, well lit, and large enough for us to make out small details such as resistor color codes.

A sound clip would also be helpful, if you can provide one.

Here's some pictures of the board.

Here's a few more.

Here's a sound example too.

You should expect some loss of highs. The signal is going through several high pass filters to get rid of the high frequency clock noise. This is simply the nature of analog bucket-brigade delay effects. But your sound clips sound a little extreme....I think....maybe. It's been a while and I don't have one handy, but I would need to plug one in and listen again to see just how much high frequency loss there is. My first guess is that you have one or more of the capacitors in the filters mixed up. I don't see any resistors out of place, but unfortunately, we can't see the caps. Please check those.

I appreciate the suggestion. I've double checked all the capacitor values and everything is correct. I've also confirmed that both trims don't have any bearing over the top end too, so ruled that out. Thanks.

Was just playing through my own AV, and while it cuts the highs to a slight extent, it's not as pronounced as in your sound clip.

Since nothing in your build looks misplaced, I would suggest working through this process: viewtopic.php?f=9&t=52188

Even though the quality of your soldering looks VERY good, it only takes one weak joint in the wrong place to create a problem. And the AV obviously has a lot of solder joints. It won't take all that long to work through the pedal, and this approach has solved numerous problems where we haven't been able to visually discern any faults in a build.
