Title: VFE Dragon Hound BOM?
Post by: brucer on October 09, 2021, 07:16:05 PM
Hi all.

I picked up a Dragon Hound PCB in the past.  Does anyone have a BOM or schematic for this circuit?  Suppose I can follow the silk screen, but I'd like to cross-check, if possible.

Thanks, Bruce.

He sells the diy files now separately from the boards on the vfe site. I did have his older Dropbox links for the docs posted on another thread but they no longer work. I believe there may still be a schematic for it in the photos section of the vfepedals Facebook site.

Thanks for quick help.  I purchased the download from VFE.  Cool to have that option.  I had no idea.

Dang I should really offer this one. Now that I look at it I'm digging the idea behind the Dragon Hound.

Ah, no wonder I couldn't find it. Am I looking at a rat type circuit and a modified tube screamer 2 in one?What is a D1M pot?

Yep, it is the Alpha Dog "Adrive" and Pale Horse 'Pdrive" mixed in parallel with a shared filter control.

I would have loved to have seen a version with a series-parallel switch and the filter control moved to independent trimpots

D1M seems to be Exponential characteristic pot?

The D-taper is a sharper log taper than an A-taper.

I have an SPS dragon hound in progress right now. I definitely agree that it'd be awesome to have a series/parallel switch.
