Title: Fun with Transformers!
Post by: dan.schumaker on December 30, 2019, 10:17:35 AM
Here are a few of my recent builds.  I've been having some fun with transformers!

Vesuvius - This is based on the EQD Eruptor.  At its heart is a Silicon Fuzz Face with a pickup simulator at the front end to make it play nice with others.  Single knob for bias adjustment and I added a switch for input caps.  It is just as nasty sounding as the demo's make it out to be.

Bitter End - This is an Octavia in a 1590A.  I know Pickdropper has already done this, but I wanted to give it a try as well.  I have the transformer mounted on the pot mounting daugherboard, and that is what gives it the height clearance it needs.

La Plancheta - This is similar to the Dunlop Siete Santos Billy Gibbons pedal.  I really like how this thing sounds.  I've never really played with a graphic EQ before, but it sounds amazing to be able to really boost or scoop the mids out of this.  Turning the octave off and playing with the EQ, it is a super versatile fuzz.  And adding the octave back in really brings out the nasty.

Howitzer - This is based on a pedal from everyones favorite pedal company.  I had never built an Astrotone Fuzz before, so I wanted to try it out.  Another cool sounding and versatile fuzz.

So much masochism. Are those mini transformers?

They seem a little smaller.  They are 42TL022's from Small Bear.  They work really well in this situation.

I was thinking it was going to be photos of Optimus Prime...

Did you design the EQ circuit based on the Dunlop? What are the surface mount ICs?

Those look great! I can't believe you're fitting those transformers in 1590A's. I'm not sure what to expect next.

Also I gotta say, if you're having fun with the transformers you may want to look at the Escobedo circuit snippets. He has some cool transformer stuff in there. The Bronx Cheer and the Jawari are both very much worth building.
