Redundant Zombie chorus advice.

[morcey2]

I built a Zombie chorus a couple of months ago.  (original thread here:  http://www.diystompboxes.com/smfforum/index.php?topic=59784.0  ) I originally used TL072s for the op-amps.  I ordered a bunch of TL062s and threw some in there.  It sounds much better.  Smoother and much less harsh.  Still had the infamous 'tick' though.  So I did Mark Hammer's "tick-fix" and now have an awesome chorus.    With the right settings, it almost sounds like a leslie, which I really like.  I finally mounted it in an enclosure and added it to my pedal chain.  I haven't gotten sophisticated enough to have a pedal board yet.   

Thanks to everyone here for the help.

Congrats!   Once you get over the humps, it's a nice little circuit.  And yes, when the delay range is adjusted right, so that it sort of straddles the chorus/flanger range, it does make a nice slow Leslie sim.

Take a look at the various CE-2/Small Clone mods described over at Tonepad.  Although the component numbers/values are not the exact same, most of the mods apply to the Zombie as well and are simple to do.  Mine has a 3-position delay-range switch (instead of 2 as in the original), a 50k wet-blend pot, and a wet-lift for vibrato.  I prefer a wet-blend pot to a wet/dry balance pot simply because  I have yet to find wet-levels of more than 50% but less than 100% useful, but that's me; you may have different needs.  Just note that if you do install a wet-level pot,when the dry side is cancelled for vibrato, you'll want to have the wet-level set to max or else you'll lose output.

I tried the anti-ticking fix with the two 10K voltage divider.   It works OK although now the speed or rate pot doesn't work at the full range that it used to.  Also it's a little bit more choppy than it was but it sounds more Leslie-ish now.  Has anyone else noticed this?
