Durham Sex Drive

Original info:
"I designed the SEX DRIVE pedal to fulfill the very particular needs of good friend Charlie Sexton.
 The goal was to build a “clean-boost” pedal that would supply additional bottom end and sustain when needed. The pedal would have to provide a boost that would not alter the original quality of the amplifiers natural tone. Most important, was to not add a “nasal” tone like the other pedals in his effects graveyard.
The result was the SEX DRIVE pedal"
You can find the original FSB thread here.

  1. Nice job man. I had this one waiting in the wings to do, but hadn't gotten around to it. Supposed to be a real nice boost/OD.

  2. Tag it. It's actually a really nice boost with a little grit at the high gain settings. The compression is pretty subtle, but it's supposed to be. I lie it better than the show cause that one colors my tone too much.

    1. I like it better than the sho. Stupid auto correct.

    2. Hey Kirshman how's the tone control on yours, mine seems to not be doing much.....

    3. it's pretty subtle through most of the sweep, but in the last 1/8th of the turn makes a pretty big difference. Seems to mostly effect the highs, but also some of the mids. Not as drastic as some of the tone knobs on here for sure, but noticable.

    4. OK thanks very much I'm thinking I have an issue

  3. Hey thanks a lot for this layout I've been interested in this pedal for awhile, question; either I've made a mistake or this is a very subtle tone control, I'm not sure I notice a difference can you advise.

    1. Hi Eric.
      I haven't built it myself but from the videos it sounds kind of subtle.

  4. Ok thanks for your help that's what I was hearing as well but either my ears are a bit gone (real possibility) or there is no change, maybe some else who has built can comment.

  6. Hi guys, want to built this one but i don't have D6. Is it on the power only? Thnaks!

    1. D6 is indeed for polarity protection, i would build the rest and still order that diode, you can than just cut the trace and add it!

  8. The mine is too clean. Full gain it remains very clean. Why?

  9. What are folks using as the CLR resistor? I have yet to run across this in my builds and it has me stumped.

    1. There is no set value for the CLR, as it's the current limiting resistor for the LED. Use whatever value you would use when wiring up an LED offboard. Personally I like my LEDs to be bright, so I normally use 2.2k, a lot of guys use 4.7k, but really you can use anything as long as it's not 0r, as the LED would blow. Remember that the lower the value the brighter the LED.

  10. Any hints on how to get a tad more gain out of this build?

    1. Maybe by increasing the gain pot to 500K or 1M.
