  1. So.. It's verbatim to triangle with 120n caps in place of 100ns. Somehow all the BMP variants just make me smile :)

    1. The tone stack is different too, this is very scooped in the tone stack sim which is why I had to greatly increase the caps on the switch to give you a flat and boosted response. Plus the minimum sustain resistor is a lot bigger so it should be quite a bit dirtier in the fully CCW rotation and a couple of other slight value variations, but yeah it's certainly close enough to know exactly where it's come from! :o)

  4. Tag it.

    I did a few slight mods, but the layout is still valid. I don't know why, but i've grown to dislike switches a lot lately. I even bought a batch of better quality switches than the usual cheapo crap, but now i'm just leaning towards minimum control/versatility... Anyway. I omitted the switch and subbed the 4n with 68n for slight rise for the tone stack middle curve. I used 8K2 in place of 7K5s. For cliping diodes i used 1N60Ps, which i hadn't used for BMP before (Let's just all face it. All these are basically just BMPs :)), and it's not bad. Maybe not as loud as your average BMP, but there is another viable explanation for that too.. I used 2N2222 (measuring 300-330 hFE) for transistors and that makes it much smoother. I also went with B100K pots for all three as the muff always works fine with both, log and lin pots.

    One thing about the layout itself.. I've always used a wire from top to bottom row over all the components on other BMP layouts, as i just hate to have two grounds on one board. Started to build this and noticed that this has a link there by default! Thanks! You read my mind!

    Makes a good alternative to basic BMP. I just have too many of those.. :) This will get a box, but it's not currently very high on my boxing list.

    1. Nice one man. I thought you had enough muffs! :o)

    2. So did i :D

      Those tiny mods made this somewhat different, so it's definitely worth boxing. 1N60Ps suit it even better than i imagined. Maybe i should have used 1N4007s for the other stage... Nah. It's good as it is.

      I had to do some other stuff today, so i didn't get to sink in to the zone. Tomorrow is hopefully a better day :)

  5. Love the comments both you guys make! If one looks a bit deeper, he can learn something! Where do you get the schematics for all these boarded effects? Steve G.

  6. Man, if you like a fuzz with sustain until the end of time, this is your pedal! Play a power chord, go out and get a bite, come back and you'll still be hearing that one.
