The Worlsd smallest flangers....

[solderman]

.....well, thay are not that big any way.

This is the story of tree flangers that wanted to be built. Two are and the third has to wait for a while.

Of course, if you want to use the layouts you don't have to box them in a 1950A. They will fit easily in a 1950B and use normal size pots and even accommodate space for a battery MXR style.

Flanger No 1 The SUBWAVE
This is a clone of the Guyatone FL3. It is based on the MN3207/3102 kombo. This means that it will not produce the really deep Jet flanging. Never the less the designer of this circuit has done a grate job with filtering the sound. It produces a very liquid and musical sound that is really pleasing. So this is a really useful effect in real life music situations. The Jet effect are fun but not that useful all the time. It's really good for flanging clean tones.

The PCB
OK, ready to build. I hate to drill PCB:s


On the road to music. Some components mounted.



And ready for testing


Some times it does not work. But there is always a reason. This time it was a solder bridge shortening the LFO.



Nice, it fits in the box. I have to remember to turn it the other way around for the final fit.


Hook up wires are always a hassle in these small boxes. Small pots fixated helps. The wires are easy to fix in a ordered manner.




Time to paint some boxes. There cousin the Tri vibe "Good Vibe" was painted at the same time


And the final result



And here are some sound samples of the SUBWAVE

Flanger No 2 The BIG WAVE
This is the Ultraflanger by John Hollis. This is a really raw "all in" flanger. It is based on the MN3007 and the clock generation is made from a 4046 buffered by a 4049. Very much like the AD/A. This gives the citcuit the possibility to drive the BBD much harder/faster that results in the capability to produce crazy sound. It's a veritable sound toy. It's Capable of everything from normal flanging to "sounds from the other side". The rudeness of the circuit with no more then the minimal necessary filtering makes it a bit distorted. This makes it most suitable for flanging distorted or squeezed tones.

Ones again that F-N drilling


Yes, I know I am a sissy to socket the BBD but a 3007 is to pricy to waist on something that doesn't work. Fortunately this one did.


Ready for testing. I decided to make the "Manual" control a trim put with a knob. Unfortunately I miscalculated (goofed up) when I drilled the Box so the hole was 5mm a side of centre. The knob did not fit so I have to adjust it by a small screwdriver.


And the final result

Flanger No 3 The BIG MisterY  (not mystery)
This is the AD/A. I have decided to try to get it to fit in a Hammond 1950BB box. I'm still working with the PCB layout. My aim is to have all 5 pots soldered to one PCB with all of the LFO on it and the rest of the audio part on another PCB. Updates will come as soon as a result is presentable.

[frequencycentral]

   I refuse to believe that such small flangers can exist! Goooooooood work! Please send them to me for full and extended evaluation.   

[ehofherr]

Those look and sound great!  VERY SMALL....outstanding job!

[kurtlives]

Your layouts have progressively gotten better and better. Your using Eagle now I think?

Pedals look great. Very clean.

[davent]

Brilliant!!! Fantastic work!!!

[12Bass]

Nice job!

[Slade]

Really impressive work, solderman, I'm stunned... They sound awesome.
I think it's time for me to build a flanger, and thanks to you I can do it now. Thanks for all your work

[Quackzed]

wow! you have to respect the limit of space; switch as standoff,staggered jacks, super clean tight layout. You have defied it!
sho-nuff !!!

[MikeH]

holy crap!  a flanger is the only effect I have never tackled and the fact you fit one in a BB makes me feel like a total hack!  Ok, time to do a flanger.  Good work man!

[humptydumpty]

i believe those are a's

[MikeH]

i believe those are a's

Thanks for the clarification- for the record, it's 1:40 am here and i just got home and I'm HAMMERED, and yes; humpty is right: those are a's, not b's.  Still f'ing sweeeeeet!

[PedroTejada]

WOW that's tiny! 

Time to sell my Boss BF2, buy BBDs and go to the working bench! 

[Jarno]

Look at the size of that footswitch! Stunning work!
Have you considered sandwiching two smaller boards in there? Or SMD?

[solderman]

Hi
Thanks' a mill every one for your nice words.
No, SMD is cheating. Only pure analog audio and build technique
The layouts are made with DIP trace from Novarm
http://www.diptrace.com
The version I use is the freeware version of the Pro version. Only limitation is 300 pins limit, non-profit use only. I have tried Eagel. It is also a very resourceful tool but DIP trace is more user friendly and have not the steep learning curve that Eagle has.
All my earlier work has been made with DIY layout creator. It's a great tool for small uncomplicated layouts. But I would never have been able to do the falngers with it.
I will go back and redraw some of my 1590A layouts with Dip trace. Among those are the Rebot delay, The Zombie Chorus, MXR Phase 45 and 90. This will omit a lot of unnecessary jumpers and unwanted cables. But that is a job for the future.

[gigimarga]

Fabulous work solderman!!!
All my flangers are huge (electric mistress and mxr), so it's fantastic to see yours!

The only important stompbox that I didn't make yet is A/DA Flanger, because it's huge...so I am very curious to see your PCB for it.

[oldschoolanalog]

Seriously nice work!

Are you planning to mount the pots so the box will take up a (IIRC) 94mm(3.7") wide footprint, or a 119mm(4.7") wide footprint? Side or back mounted jacks?
Inquiring minds, and all that...

_{Lets test some of you geezers out there (I love you all). Those are some wee pedals. Nice man}

Solderman,

With the wide availability of dual op-amps in SIP form (i.e., many of us here could easily make use of them), feel free to use their space-conserving qualities to keep the PCB footprint small.

[solderman]

Seriously nice work!

Hi
My plan A is to have the two boards parallel on different levels. The LFO board in front and at the bottom. This will accommodate jacks (In 7Ut Power) from the front. I would like to avoid them coming in from the sides as this steals space. If this won't kork plan B is to have the LFO PCB standing at the top. Unfortunately I will not be able to fit the jacks in the front then. I plane a 119mm(4.7") wide footprint to have all 5 pots lined up. The volume is going to be a trim pot that is set and left. I can see no big reason to have it as a panel pot. The thing is crowded with pot's as it is.

As Mark wrought, surface mount is a possibility. And Diptrace has layout templates for it. But I will save that for later. I don't want to do it all too soon. Have to save some fun for the future.

Here is the LFO part NOT VERIFIED I have not even had time to check it a second time. The cut corners are there if I have to have it standing.
