Lovepedal - Dover Drive  [traced]

Postby Kennc_dk » 30 Jun 2017, 22:45

I have traced the 'Dover Drive' pedal from Lovepedal.

Seems like that hints from this forum were right: It's a blend of a fuzz face (dragon fuzz) and a zen drive.

Please let me know if you find mistakes or have observed differencies in component values from pedal to pedal.

Here's a stripboard layout... Currently unverified.

Thank you guys!
I wonder a cut under the D3 is needed.

Yup. That cut is missing from my original file. Sorry about that. Fixed the layout....

Thanks so much guys!!

Maybe the 81k/120k voltage divider should be replaced with a 200k trimpot? Are those fixed resistors in the original?

Thanks again!!!

yes, the two resistors are discrete.
They are highlighted on the picture attached, they are at the back left.
The reason why I think* that they are 'tweaked at the factory' is because they are very precise values and completely different values from the rest.
*That divider ratio solution, using two unique resistors values is expensive, from a production point of view.

The two resistors are used to match the clipping point of the 'zen' overdrive with output amplitude of the 'fuzz face' ;-)

Makes sense!! Many thanks, Kennc_dk!!

Got two PCB layouts worked up, getting ready to order a small batch. :thumbsup

On one I've substituted the 81.2K and 121K resistors with a series pair (75K + 6.2K, and 120K + 1K respectively) to make parts sourcing a bit easier.
On the other I've replaced them with a 25-turn trim pot, this should allow fine tuning.

Couple slight errors on the previous stripboard layout. This should work.

Damn. Had the gain labels still in reverse. I seem to be slightly off my game... Anyway. One of our blog builders built this and apparently sounds very close to the original. So consider this verified.
(Also, if one of the mods would be so kind and remove the crap files from above - thanks!)
