ZVex Box of Metal

Another one to keep you busy for a while.  This version is the effect only and no gate so you'll have to use an ISP Decimator or something with it if it's noisy :o)

  2. 180pf instead of 2n at Q5,is really really better !!
    I tried 2n7000 instead BS170 for all transistors,this is little more accurate.
    I'll try 220nf input capacitor,to use it with a bass.
    I will keep you informed of what happens.

  3. The Bass mods with the 220nf,works fine !

  4. Are the 2n7000 better than BS170?

  5. Not really...
    Both works fine,2n7000 sounds more tight and makes the Box of Metal a little bit more accurate,but that's all.

    1. Never mind I answered this one myself!! I have to say though, between this and the Dr. Boogie, I'm really disappointed in the Triple Wreck!!
      I hope it's still something I've done wrong but haven't found the mistake yet!!

      Cheers Thommo.

    2. I've been wondering that myself. Do the empty lugs connect to ground? Thanks.

    3. Yes,it's Gain 1 & 2 to ground.

    1. It allows you to set the gain for Q5, too much will be noisy so it will let you fine tune it.

  9. Sorry, but i have some silly question, what is the thing on the top of Q5? The 5k with 3 pin on it.
    And what is 9v1 Zener?

    thx alot

    1. It's a 5K trimmer, and a 9V1 zener is a 9.1V zener diode. You'll find both for pennies on eBay.

  10. Cant find any trimmer and 9v1 here.
    could i swap it with something else?

    Thanks

  11. What wattage should i use for the 9v1 zener diode?

    And how can i deal with the noise later? Since i dont have any noise reducer or decimator

    Thx btw

  13. Hi,

    Great vero, thanks. Just one question tho, my bass pot seems to do nothing, everything else is just fine. Any idea ?

    ReplyDelete
  14. I put a Vero layout with a working gate over at freestompboxes
    http://www.freestompboxes.org/viewtopic.php?f=7&t=3911&p=247046#p247046
    Please build and comment. It works fine for me, but it needs some fine tuning.

  15. I can't see stuff on freestompboxes, don't have permission or something...cannot be bothered to sign up for another blog. This one is the one for me.
    Can you upload it to here for the scrutiny of the fine community?
    Thanks sir!

  16. Just built the vero version on freestompboxes with gate and it works fine although bass doesn't seem to do much? Just got to figure out how to squeeze it all into the 1590B box!!!!
