1. I believe with a couple Op-Amp/MOSFET buffers you can achieve an FX loop. Just put a couple buffers on a vero daughterboard and connect those to some 1/4" jacks. SEND would best be tapped off the positive side of C19 and the RETURN connected to a blend pot to the positive side of C22. Not sure on the connections of the SEND/RETURN jacks, someone'd have to back me up on that (or correct me if I'm wrong).

2. I think to increase the short reverb type delay repeats, you'd have to install a larger value "SPACE" pot. I'd start with 25k and if that isn't sufficient move up to 50k.

Good luck!

Nice job! I love the reference to Maximum Overdrive :D

Just checked all connections again, plus my resistor values.
Found out I had a connection going from Q1's emitter to R11... that explains the strange voltage readings.

So, problem solved :) thanks for the nudge in the right direction!

Hey guys, I've got the same issue so I figured I'd revive this thread...

So my problem is pretty much the same as strat68's. The signal 'disappears' after the base of Q1 (tried audioprobing past Q1's base, no dice). I've reflowed some 'suspicious' solder joints, measured connectivity yet the problem persists. I'm pretty stumped as well 'cause I've had many more complex builds before this which worked right off the bat.

I measured the voltages of my sockets (with and without tranny's), could you guys mayhap take a look at it and point me in the right direction of where to look?
Thanks a whole lot in advance!


Sockets without tranny's:

Q1:

C 9.33v
B 3.62v
E 9.30v

Q2:

C 9.38v
B 9.33v
E 0.00v

Q3:

C 9.33v
B 0.00v
E 0.00v


Tranny's in their sockets:

Q1

C 3.44v
B 3.48v
E 3.44v

Q2

C 9.03v
B 3.44v
E 2.88v

Q3

C 3.44v
B 2.88v
E 2.21v

Looks fantastic! I'm curious as to how it sounds.
Any chance we get to take a look at the guts of the effect? :)

Man, that looks fantastic... loving the big knobs on there. Great internals as well. I second the sound demo!

Thanks for that juan, that'll definitely come in handy!

Super clean, looks great! Any chance for an audio demo? :)

Your demo is really great, now I want one.   ;D     I do have a couple of questions.

I know this pedal runs on +/- 12v.  In your previous post I think you said that you were powering it with a 9v adapter.  I assume that's what you're doing on vero.  How do you accomplish that?

How effective is the ramp up / down feature?  Is it at all like a Leslie?   

Thank you very much!

I have no idea how effective the ramp up/down feature is, I didn't populate that part of the board so I can't try it out unfortunately. I decided that due to my plans to use an expression pedal to manipulate the speed, I wouldn't need it as I could just gradually increase/decrease the speed myself.

Indeed, I am using a regular 9v adapter. I just take +9v from the 2.1mm adapter jack and use a voltage inverting circuit on vero to get -9v. I did alter some resistor values (on the main PCB - required for proper operation I guess) though, can't recall exactly which values but if you check out the project page on MFOS it'll tell you which resistors to alter for +15/-15v operation. I believe I decreased the values and even used trimmers in some spots. Fiddled around with 'em for a while 'till I was satisfied :)

Damn, thats a sound I've been looking to get for a very long time.  Don't know how I'd work stereo into my live rig but that sounds just crazy good.  Nice and subtle but however the pseudo doppler effect is done (either real or imagined) is too cool.

Likewise! I simply use two amps set-up facing eachother at home. If I'd do it live I'd probably set the two amps as far apart from each other as possible, to achieve maximum effect.

EDIT:

I'm sorry for the slow reply guys, had quite a busy weekend.

Looks absolutely spiffing :) I like what you did to the center-knob!

Thanks everybody! Glad ya'll like the effect :)

Man, there is really nothing I don't like about this pedal. Thanks for sharing the clip. I love the way it sounds with the phaser going. I kind of want to build one now. You're not helping me avoid branching into analog synth stuff. I've drooled over at MFOS a lot. Just curious, what's going on with the unpopulated sections of the board?

Thanks for the compliment! Haha, I know the problem; when I first heard a sample of this effect on MFOS I just HAD to have it... immediately ordered the PCB while I still had some unpayed bills due... hehe.
Anyway, the unpopulated section of the circuit is actually a ramp up/ramp down control for the speed, much like the original Leslie speakers had two speed settings. I figured since I was going to use an expression pedal to fluctuate the speed while playing I didn't need it, as I can gradually increase/decrease the speed myself (or less gradually for more extreme effects).

Wow, sounds absolutely fantastic... think this'll be the next phaser I'll be building! :)

Hey folks!

Here's a seperate topic about the Auto-panner I posted about earlier in my introduction thread. I recall that jimilee asked for an audio demo so I did a quick little recording using two amplifiers in a stereo setup. In the audio demo I'm using an expression pedal to modify the panning speed of the effect (this is also switchable).

On the left I'm using some sort of Marshall clone from the 80's (it was given to me by an old friend a couple of years back, runs on three AX7's and two EL34's with a Baxandall tonestack... or at least I think so :o ) and on the right sits a 60w Fender Deville.
I'm also using a MiM Fender Strat with DiMarzio hotrails in the neck and DiMarzio 'buckers in the bridge. The bridge 'buckers are coil-tappable.

Other effects I used were a GrindCustomsFX Tenebrion reverb on the Marshall clone, a touch of spring reverb on the DeVille and later on an MXR Phase-100 clone and a DOD FX65 chorus.

Most of the 'modulation' came from the Auto-panner though. Guess it 'sounds' like modulation due to the ears being tricked there's a phase shift of some sorts going on, yet all that happens is the fluctuation of volume from left to right. I don't know a whole lot about this subject, so please forgive me if I'm wrong (I'd love to learn what causes this funny effect though!).
Oh, also, I could finetune the effect to be completely off/on on the respective left/right channels, but I figured this sounded best. Sounds a little like some sort of Leslie, I really dig it ;D

Enough text, on the audio demo! I recommend listening to it with some good headphones to emphasize the panning effect.

Thanks ya'll! I really dig the look of 'used' or battered pedals as well. The muff clone was purposefully 'reliced' for this reason (was actually a failed paint job so I figured I'd finish it off like that).

About the auto-panner, I'll post a sound clip of that sometime tomorrow. Might dedicate a thread to the effect as it can be used quite diversely - depending on how you set up your amps/cabs, or in combo with a stereo delay or other modulation effects.
