Thanks, Anthonie! I'll give that a try tonight!

Hi Anthonie,

I finally got around to taking a look at the Zombie last night. I desoldered pin 4 from pin 5 on the MN3007 (well NTE1641 for me

) and realized I was gonig to have to find a spot to grab 1 V from. My bench is a disaster (working around my latest tube amp project) and there's no room to frig round with teeny circuits at the moment...so I threw it back in my "projects" box in disgust.

Actually my pedal sounds good aside from the background hiss. I have no LFO ticking, but the noise is intolerable. I think I'm just going to build the Tonepad Small Clone - I've heard nothing but good things about that project. Oh, one thing I noticed - pins 4 & 5 of the BBD are tied together on the Small Clone, too... I don't even really like chorus pedals so I don't know why I'm bothering.

One thing I do like is that Wiggler that EH is selling right now - fantastic job! Is that based on any "classic" amp circuit or is it strictly your own creation?

Take care!

Jim

the WIGGLER is based on the same technology that inspired the late great
Dick Denney (designer of the VOX AC 30),
namely electronic organ stuff from the 50`s.

Hi Anthonie,

Cool - thanks for the info! I'm thinking of building a standalone trem/vibrato unit (that'll look like a mini guitar head) and was wondering if I should go the whole nine yards and make it a tube phase shifter. I guess if you're making a true pitch-bending vibrato, mixing in "straight" signal is all it takes to make a phaser.

Do you yourself use more than two stages? I kinda like the sound of the Phase 45...

the Wiggler works different than the average commonly used phasers...

So tell us Anthonie... how exactly is it different?

Jim Jones · November 07, 2003, 12:35:58 PM

Thanks again, Anthonie. I don't want to drag proprietary information from you!

Take care!

in that it is not the typical AllPass configuration thingy...

Quotein that it is not the typical AllPass configuration thingy...

Must be one of: the phase splitter version of phasing ala univibe and before that the Magnatone vibrato or the dual-band alternating hi/low tremolo as in the Fender Concert and a couple of others. I did a phase splitter tube phaser version of the univibe a ways back. Both of those are pretty easily per/converted to vibrato/tremolo/phasish sound.

Yes?

sorry, none of them (though one gets close).

these 2 do come very close to your descriptions:

But I`m very glad somebody finally mentioned that
(in-)famous "Fender-Trem" by what it is.... (Hi-Low).

The soul-less revenge-engineered schemos appearing on the web contain multiple serious
