Fuzz Transformer (Harmonic Xformer)
« on: April 16, 2015, 10:44:24 PM »
One more today.

This is a DBA Harmonic Transformer circuit I did an smd layout for as a collaborative effort between myself and Dan Minner.
http://www.madbeanpedals.com/forum/index.php?topic=19594.msg202933#msg202933

I did the pcb layout and soldering, he did the killer graphics and etches.  Great guy to work with, I really enjoyed breaking things up a little from my normal approaches.  Love the collaborative approach he started.

Going to the PO tomorrow, so he should have it next week.  I probably wouldn't have known about the circuit if Dan hadn't suggested it.  Its pretty fun. 

I'm still not really a fuzz guy, but this has some interesting qualitites and a crap load of fuzzy, sustainy goodness.  Gets a little splatty if you turn down the volume at the guitar, which can be cool in small doses.  The switches actually make a big difference too.

Not quite as crazy as a fuzz factory, but probably a bit more musical/practical.







Thanks for looking!

Nice looking unit!
this build is so clean! And the etch too.
Where did you found this kind of led socket?

Wow, great work all around! I know Dan usually prefers to go a size bigger for the box but his design and etch on this 1590A looks fantastic too!

Thanks again y'all. Can't wait until he gets it.

Don't know where the bezel came from, maybe Dan will chime in.

True!  I did a little finger crossing but glad he agreed. Love it

The fresnels were from mouser or Onlinecomponents, I can find the part number later and post it. They are for thicker enclosures, but nothing a tight hole and a little superglue can't fix.

And yeah, this was a stretch for me. I didn't realize how heavily I rely on large pot markers, etc in my designs until I couldn't use them haha. It was a bit out of my comfort zone but I think the next one will be better, I have some ideas brewing ;)

I've some of those bezels as well as a result of punching in the wrong part number, wanted rounds; Mouser part# 593- 2500A, but better check to make sure.

really cool... I totally dig the graphics, knob and bezel... deliciously retro
your gut shot is so tidy, it looks like you built it in a 125B!
