D*A*M: Drag N Fly

Haven't done a D*A*M layout for a while, and it could easily be said that I didn't do this one either...  it's a copy of one of the D*A*M layouts - there were a lot of layouts used for the Drag N Fly over the years. 

Bit of speculation on some values, so I looked at some other layouts as a reference; the rest is from photos.  It's a hybrid silicon/germanium NPN Vox Tone Bender with an input blend.

 

DRAGONFLY / DRAG N FLY HISTORY

Although which layout is it a copy of?  There are so many…  check the D*A*M forum post here  https://stompboxes.co.uk/forum/viewtopic.php?f=14&t=316

NOTE: The Dragonfly is a different circuit from the Drag n Fly.  Still a fuzz face under the hood, however, the Dragonfly is built on 0.15” vero, with a fixed input cap, with the Tone control being a blend on output caps.  

DRAG N FLY VARIATIONS

These are just some that I've seen; there are probably more.  As you can see, maybe don't stress about the transistor section too much, as long as you like the sound.

• 10k instead of 18k resistor on Q1 collector (probably transistor selection related)

• 2 x trimmers for biasing, which I'm guessing is to replace the resistor on Q1 collector

• 56k resistor instead of 120k between the base of Q1 and the emitter of Q2

• 10uf and 3.3n on the input blend

• Q1: BC108, BC107B and plenty more unidentified silicon

• Q2: AC176, OC76, OC82, AC128, CV7112, OC140
