Hi Charlie, some years ago someone released a schema of your "cutting edge" pedal, not produced anymore. Because I was not satisfied with the Gemini I asked an electronic guy to build it for me and it worked fine until it got lost. I searched the forum up and down but cannot find the schematic anymore. Can you PLEASE help me to get it again. Thank you Pinot

Thank you very much! My plan is to build it as a rotary switch into my Strat. Kind regards Pinot

Do not build the Cutting Edge circuit in your guitar! It will work but will not work properly. It is best to put it between the echo unit and the amp.
Regards,
Charlie

Thank You all! My problem with the Box was that I use a Strat for Shadows and a Gretsch CG for a lot of other music via the same line: guitar->Compressor->EQ->Echo/Reverb->Cutting Edge Box->Amp. Many times when I change guitar and have to change Q+ program I forget to switch the box on/off and wonder why the CG sounds so dull and so on. Therefore was my idea to put it to the right place (the Start), but if it does not work there I will put a big poster on my guitar rack and concentrate more ;-).
An alternative could be the Neutrik plug with 4 different capacitors from neutral to +1 or +2 or +3 nF. Some guys report that it cut off the sharpness of the Strat's bridge PU with no cut of treble. That is what I am looking for.

The Neutrik plug works by removing some highs, this is totally the opposite of the Cutting Edge which removes lows.

Charlie

The wonderfully clear plan of a cutting edge pedal posted by Shadowtonio above has given me the encouragement and confidence I need to finally have a go at putting together all the pieces I have had sitting on my desk for the last year!!!.
I have just one question before I start. The six tags on the push button selector I have are numbered 1 to 6. so you can see the green wire could be connected to tag 1 or tag 6 depending on which way round the switch is oriented at the start. So does it matter which way round the switch is placed as long as the connections are all as shown?
I have assumed the red crosses mean a cut/ break in the circuit.
I'm sure someone will help me out here.
Thanks
Mick

Hi Mick
That's the Veroboard layout I did some while back. I used the spare tracks to solder to a large solder tag that mounted the whole board to the footswitch boss. It shouldn't matter which way round the switch goes. The red crosses are indeed breaks in the tracks.

Hello Roger, it's nice to hear from you again and thanks for your help here. The last time I tried soldering anything it looked a real mess, so I'm not expecting it to work when I've put all the parts together!!
Cheers,
Mick

Hi Mick,
Earlier this year I manage to build one and its worth the effort, it will give you confidence for other projects.
I used a drill bit in my fingers to twist the breaks in the tracks, I also use double tracks to make soldering easier, hands not as steady as you get older, so long as you connect both tracks together with solder.
This was the way I managed it and I was pleased with the result
Regards
Carl

If the Cutting Edge removes lows what would you recommend to get off that ice-picking trebles of the Strat's bridge-PU? If I reduce trebles with the tone-control (possible on American Standard Strat since 2008?) the sound becomes dull. Kind regards Pinot

Hi Tonio, sorry for my bad English. Please forget about the Cutting Edge, what I am looking for is any way to to get off that ice-picking trebles of the Strat's bridge-PU. Maybe I would need a Cutting Edge on the other side of the spectrum, to get sharpness away without loosing the trebles. E.g. Kinman means their PUs avoid the sharpness, but it is an expensive and complicate procedure to order from Australia, now I have got the Neutrik Timbre plug and this does with less effort in the direction I want. Maybe someone has another solution too? Kind regards Pinot

Hi Pinot,
Does the 1nf setting on the Neutrik plug remove too much of the highs?
Regards,
Charlie

Hi Charlie,
the 1nF reduces the sharpness and a little trebles too, it is the only possible position for me. In my 45 years old Framus I had the same problem after I got a PUs improvement by a Munich electronic specialist, who adviced me then to use his C-Switch, this seems to be a similar solution with increasing capacitance and it is build into the guitar. If no better idea comes up I can live with Neutrik Pos. 1nF. Kind regards Pinot

Hi Pinot,
Maybe 1nf is too much. I wonder if the 1nf in the plug could be changed for a smaller value, say 500pf or 680pf?
Regards,
Charlie

Hi Charlie, I can look to find a guy in Vienna to build a cable with only 500pF or 680pF fixed, I think this should not be to difficult. Would it be possible to solder such a capacitance into the Strat's tone control? Kind regards Pinot

Post by Charlie Hall on Dec 11, 2013 19:02:16 GMT
Hi Pinot,
I have a Klotz 5 metre cable that measures almost exactly 680 pf. Remember of course that your current cable has some capacitance so unless you know the amount, you will have to try different cables by trial and error to arrive at the result you want. I am not sure if the cable is a good idea because it will affect all your pickups, not just the bridge pickup. And in any case the cable capacitance will only be effective in the required way with the guitar volume control on 10.
You could modify a Strat that has no tone control on the bridge pickup by adding the capacitor on the switch, from the unused contact to the next one along (that has a wire going to the lower tone control). Then when the lower tone control is turned right down, the capacitor will act on the bridge pickup. However when the middle pickup is used (on its own or with the other pickups) you would have to turn the tone control back to 10.
An alternative idea would be to solder the capacitor directly on the bridge pickup wires but then you would not be able to have the original bridge pickup sound, and any pickup selection that includes the bridge pickup would also be effected.
Regards,
Charlie

Hi Pinot, Does the 1nf setting on the Neutrik plug remove too much of the highs? Regards, Charlie Yes, a little, but it is more acceptable than the harsh sound in the other direction. Maybe the 6m Sommer Cable The Spirit XL is thicker then the Klotz I used before and adds additionally more capacitance. I thank you very much for so much effort to help!! Kind regards Pinot |

A Google search for vintage cable simulator may be useful

Kind regards Pinot Hi Pinot, If you have a Strat wired with a tone control for the bridge it's easy, all you need to do is to change the 0.047uF capacitor for a 0.022 or even a 0.01uF capacitor. That will still take off the "ice-pick" tones but the roll-off will be gentler, i.e. you can move the tone knob further as it is now less sensitive. Regards, Steve |

Hi Steve, after Christmas I will experiment with that! Thank you and Merry Christmas Pinot Hi Steve again, I thought over it. I have to prepose that I am no technician. I use the Neutrik Timbre Plug since some weeks an it adds additionally capacitors with 1nF, 2nF or 3nF. I use 1nF which takes off the sharpness, but sounds a little dull. This results by increase capacitors. You recommend to decrease from 0.047uF capacitor to 0.022 or 0.01uF? |

Hi Pinot, I am not really familiar with the Neutrik Timbre Plug but I assume that it allows switching of the 1nF, 2nF or 3nF capacitors into the circuit from output to ground, which will lower the pickup's resonant frequency depending on capacitor size. Adding a smaller capacitor to the Strat bridge tone allows you to vary the resonance peak because you have the 250k potentiometer in circuit as a control. Try it out and you could always put an even smaller capacitor on the tone if you still think it dulls the pickup but in my case I've found it works well. Happy Christmas. Regards, Steve |
