4ms Phaseur Fleur
This was an old request.
Layout came out quite large.
You can find all info and schematic on Commonsound/4ms website here.
Trading and gaming are the two things I most want to discuss on vero board layout comment section. I would say the circuit sounds better with an mc33172 and it is working but needs to be tweaked some. Seems like most of the pots need to be maxed out right now.
Yea it looks good but it no workie. Tried a few different led's. How would we go about just adding a regular status led to the current layout or making it tb?
Isn't feeding 9V into a 9V reg going to give you an unstable, slightly starved output? I'm not really sure why one's been included in the schem anyway, seems fairly unnecessary?
Think I can say this is verified. Takes some tweaking of the trimmers and knobs but I get a good range of sounds (trimmer turned up, the ring is insanely loud!). The LED is working for me. Thanks for the layout!

Hi Alex, I am going to try to build the phaser Fleur pedals according to your design here. I was wondering what size hammond enclosure would be good to get for it? Also are there any changes or fixes to the above mentioned design that I should need?
I actually ordered a 1590BBM, which is a larger enclosure so it should work. I am a beginner, so I have a basic question about wiring the pots. I see most of the connections listed, but the ones for ring 1, speed 1, and blend 3 are missing. I assume these are connected to each other? Also is the "rate led" the same as the "stomp led" as mentioned in the wiring diagram from commonsound? For that PCB the led is also connected to the footswitch. Should I do that for this design? Also the fsw 3 connects to fsw 9. That seems like the same wiring as for a bypass circuit. One more thing, does the input jack connect to the neg. power jack? and is there a neg. power jack connection to the veroboard?
Sorry for all the questions, but thank you so much!
I am assembling the veroboard design you lay out here, and again have a question about connecting pots. From the above wiring diagram, I can see no connections to the board for "speed 1" "blend 3" or "ring 1." Can you please clarify this for me, as I am a humble beginning veroboarder.
Just a brief question: the led on your design is for the rate (i.e. speed) control. Is that right? If so, can I add an led for the stomp switch to your board here, by connecting another led via a 4.7k resistor in between the dc jack + and few 4 position? Also I noticed that the output and input jacks have one connection each to the main board. Are these group ned on the chassis with a wire, or via the jack itself?
Thanks so much for including this cool phaser pedal design. When I finish I will give informative feedback.
Hi John, sorry for the delay but I've been very busy and once you miss the comments... First of all, if you are new to vero, I would suggest you start with building something easier. This is a hard circuit to build and if you run in any trouble it could be a nightmare to sort it out. If the pots' lugs are not on the board or in the notes it means they are not used and they remain unconnected. Input and Output jacks tips are connected to the footswitch, not the board. Their sleeves connect to Ground. The Rate LED works as a status LED. It's not "On" all the time. If you just want a regular LED instead you may want to remove the 10K resistor going from Speed 3 to the 2n5089 Base. Don't connect the rate LED or Fsw 4 & 5 to the board. Instead connect Fsw 4 to LED- and Fsw 5 to Ground. LED+ would go to +9V through a 4K7 or other value resistor of your choice.
Alex thank you, I am building it now, and figured out most of what you mention. i am going to stick to your design here in terms if the status led, one question I do have: you design states that it is not true bypass. What would the wiring be to have a true bypass foot switch?.
Oh sorry one other thing, I notice that there is no "input" or "output" on the board, only the ground and 9v+. The jacks are connected to the footswitch of course, but do they also need to be connected to the main board?
Alex, so I built this but having a little trouble. At first I used a stereo input jack. Got no guitar whatsoever, only feedback which could be altered with the pots. I tried everything, grounding the output jack, still no guitar in either on or off mode. I then used a mono input jack. So now I get guitar sound when the pedal is both on and off. Switched on I get the same feedback that sounds like a phaser, but it is not in any way responsive to the guitar which is being played over the phaser feedback, as if in a bypassed mode. Can you help me?! I'm close to getting this to work. Disconnected the output from the board ground as you suggested, ran continuity tests, everything seems to be ok and looks good. The rate led are responsive to the speed control, and the red leds are responsive to the other controls. Please help!
You need 2 mono jacks. Tips go to the footswitch. Sleeves to ground. No connection to the board. How did you wire the footswitch? It is a 3PDT but it's wired differently. It's a buffered effect. Pins' numbering is the usual: 1 4 7 2 5 8 3 6 9
Sure did all that. I wired everything the way it is shown on your page, switch and pots and jacks all correct. I get phaser-like sounds, LEDs are responsive to controls, but there is massive feedback and the guitar is just playing as normal under the feedback. I thought it was a grounding issue, but grounding the jacks just quiets the feedback. I tested things with multimeter. There are some low voltages at a few points on the board. Could it be some bad solder joints shorting it? I figured that since I can hear something, and the LEDs work that it's not shorted.
Could you please add in all the extra mods that turns the Phaseur Fleur into the Phaseur Moire: the volume mod, the waveshaper mod, and the 2 auxiliary LFOs? Maybe as daughter boards? The toner layout on Commonsound has the aux LFOs, but I don't know how they're supposed to be wired up so each one has it's own stomp switch. I think how to wire up the mods is actually a very common question. Thanks.
Ok well I finally achieved (partial) success, after a year! The phaseur works and sounds great. It did take some major tweaking of the trimpots to get some nice phasing, but the circuit is verified. There is one problem however, the blend control is not working properly. At 7 o'clock (0 position of pot) the signal is totally wet and I get the phaser effect. As I turn it from the 7 o'clock position I hear a brief shh/hiss sound, and then at 9 o'clock the phaser effect goes out abruptly, and all I get is the dry guitar signal from there on. Has anyone else had this problem? I checked and reflowed solder joints, and everything else looks good. Is the blend supposed to go from 100% wet at 7 o'clock to 0% at 5 o'clock?
Btw common sound designates a 10K pot for the blend control, yet here it is listed as a 100K, could this be my problem? Is the 100K value for the blend correct here?
Ok then so i figured out the blend issue: went onto comonsound's phaseur site, and what do I learn? There are 5 pots on this pedal, which this page suggests are all B100K. Te blend control, however, requires a B10K pot according to LMS. So I try this, and that "hiss" sounds is actually the whole range of the blend control, which was reduced to 1/10th span on the 100K pot. So my phaseur fleur pedal is now fully operational! REPEAT: the BLEND requires a 10K pot! Haha thanks.
Thanks for the layout. Built mine today, every potentiometer/parameter works, but I do hear a strange siren sound oscillating with or without any audio source going though the pedal. This sound follow the current value of any potentiometer (I mean if speed is set to fast, siren sound is fast too). It only stops when I bypass the pedal. If anyone could help me with it it would be great !
Yeah thanks! :)

ReplyDeleteSOmething is up with the rate led too. It is not working.
ReplyDeleteI've checked schematic & PCB and I'm pretty sure they match the layout. Did you double check it too?
DeleteYea it looks good but it no workie. Tried a few different led's. How would we go about just adding a regular status led to the current layout or making it tb?

I would use a 1590BB for it. There were no changes made.

Hi Alex,

ReplyDeleteOh and yes, I used 2 mono jacks.
ReplyDeleteShould the pot legs show continuity? I found that lugs 2 & 3 for both the speed and ring pots have continuity, is that normal?
ReplyDeleteIf those pots are maxed, then yes. Fully clockwise, the lugs 2 & 3 are connected to each other...
Delete+m
Yeah I see that, I just don't know why my guitar signal is not being affected by the circuit, which sounds good and responds to controls.
