Boss OD1

Info from Boss:

The OD-1 is by now legendary. Artist of the 70's was mostly using a fuzz distortion sound and the overdrive produced by the OD-1 was not typical. It was however soon accepted as the new standard of guitar sound. The OD-1 features an asymmetric circuit where the positive and negative halves of the waveform isn't distorted equally. The sound is therefore still close to the original even though distortion have been added.

  1. what a classic. Along with the Crowther HotCake,the Pro Co Rat and the Ibanez Tube Screamer this was on of the main pedals to change the music style from Fuzz and tubes to overdrive pedals and distortions.

    Now please can you try to complete this set with the Boss BD2 which is IMO the best Boss pedal ever and maybe the best non-boutique OD pedal over.

    Thanks,
    D

  2. YEAH! Glad I dumped mine on Ebay for $100 a few years ago. Now I have the parts to roll my own!

    Seconds on the Blues Driver. That one rules.

  3. I heard a lot of varying reports on Boss OD's and distortions so i had to build this to hear it for myself and i'm pleasantly surprised.

    I'll be boxing this one up over the weekend, it's a keeper ;-)

    Thanks for posting this one Mark

  4. Any thoughts on doing the 14-pin IC version?

  5. Got this one boxed up. Spent the weekend boxing up some of my other pedals as well.

    1. Pedal looks great James. How did you get the white lettering on your enclosure was it screen printed?

    2. How do you get the boxes coloured like that?

  6. Does this have the buffers on, or have they been removed?

    1. Yes it has the input and output buffers, but it has the buffers Boss use for their bypass switching removed.

  8. What transistors are recommended? Go with the standby of 2N5088's?

    1. Tried a few, for me 2n3904s worked the best

  9. I had heard this one was supposed to be great, but I am pretty disappointed. It's pretty thin and sterile sounding to my ears, with my gear. I used 2n5088s. I'll try again with some 2n3904s and maybe test some different ICs before scrapping it. Any brilliant findings will be reported.

  10. What does "Watch double link in single hole" mean?

  11. Just came around to building one. Sounds like it should, but i found the "near unity level when maxed" (aka too low level) to suck ass, so i made couple of value substitutions.
    -10K from third row to IC pin 6 - changed that to 4K7 (double the gain of the recovery amp)
    -4K7 from top row Level 3 - changed that to 2K2 (shorter path to output buffer = more volume)

    Now it boosts and still has the frequency response per, or really close to the original. Not too great, but somehow i like it. Like a boosting TS without tone control (which it pretty much is :))...

  13. Hi, do you have the original schematics so I can take a look at the circuit? I'd really appreciate it. Thanks!
