Danelectro Vibrato --> Univibe (take 2)

[Chris S]

A little while ago I did a post about converting a Danelectro vibrato (chicken salad) to a univibe. I falsely asummed that this pedal would do the vibrato side of the univibe instead it does the chorus/phaser side.

So now my question is has any one worked out how to convert this to a vibrato? It would mean cutting a connection somewhere. There is an east west jumper wire on the smaller curcuit board that i thought might be it, but these suckers are really delicate and I didn't want to start attacking it with my heavy soldering hand without a second opinion.

Oh and if anyone had worked out which capacitor needs to be changed to make the speed faster that would be much appreciated too!

MANY THANKS!!!

To get vibrato you'd have to disconnect the dry signal where it's blended at the output, but without a schematic it's a bit difficult to offer advise.

To make the thing faster, the dumb way to do this (but safe) would be to follow the connections of the speed/rate pot back to the board and look for the nearest cap which connects up to an op-amp (I'm assuming they've used a simple triangle LFO, though this may not be the case).  Croc clip a cap in parallel with this (not as easy as it sounds as they've probably used surface mount stuff if it's anything like the Dano stuff I've seen so you might have to use meter probes) and see if the rate slows down.  If it does then you've probably found your cap, just make it smaller (again, easier said that done if it's surface mount).

:oops: Of course, that's what I did to find the capacitor that affected the speed on my Cool Cat Chorus.

Any other chicken salad owners out there who've been modding away?
