Looks like these beauties will be on their way soon.
One question/idea. Does any one know of a suitable pot for this project but with a centre dent? Ideally one with a 6mm shaft as that fits the knobs I am using. I am UK based but Mouser etc have UK distribution. I have seen pots for guitars with the correct value and a centre dent but I would like to look at alternatives.
Centre dent just makes sense for the design. _________________ http://soundcloud.com/for-mash-get-ash |

depends. in the past i tried several pots with center detent, and they all had two problems more or less:
1st, you will loose a bit of the fine control around the center detent, just because you have to move the pot 'over the brim' (i don't know how to describe that in english). what i mean: you have to move the potentiometer a little bit in order to make it stay where it is and not to move back into the detent. alas, you need linear pots (actually, read below), and thus you will be very interested in the area near the center for control voltages.
2nd, anytime the potentiometer goes back to the center detent the resistance is slightly different.
actually we needed a center taped potentiometer with detent, which has a log response CW from center, and an antilog response CCW from center. this could only be a custom potentiometer with a MOQ of 10.000pcs.
however, YMMV _________________

Thanks for those tips. I understand exactly what you are saying, I couldnt have put it better either. Even all the Fonik-fans couldnt raise an order for 10,000 pieces....
I will try a could and see what results I get _________________ http://soundcloud.com/for-mash-get-ash |

I will try a couple and see.....
The Attenuverter boards arrived today in London. Thank you very much. They are tiny, I didnt think I had all the boards I asked for when I looked at the envelope!! The size means they will fit anywhere. _________________ http://soundcloud.com/for-mash-get-ash |

Hi! Last weekend, I installed an attenuverter on a new module and it works perfectly! Look forward to adding it to some of my existing modules.
Thanks! _________________ -- Kevin

I used a 100K linear pot and a 100K trimpot. All the other values are as you specified on the schematic (all 1% resistors). _________________ -- Kevin

I used an Alpha -- I'll have to get the part number to you when I get back home. _________________ -- Kevin

Couldn't you add a 1M fixed from the wiper to each end of the pot, thus putting a 'hump' in it's response? Or are we looking at the reverse effect here? Just an idea. _________________ What makes a space ours, is what we put there, and what we do there. |

Im sorry if this is a basic question but can you put audio signals thru this to flip the phase?
Thanks |
