Q about Range control on Electric Mistress

[Mark Hammer]

A friend is thinking of producing an EM clone in a 1590B package using a couple of smaller-footprint substitutions.  In discussing it with him yesterday, and looking over the EM schem posted over at GGG ( http://www.generalguitargadgets.com/diagrams/dmistsc.gif ), the Range control struck me as a little different than usual.  Obviously, manufacturers are free to call a control whatever they want to call it, given the intended market and use.  In this case, the name struck me as perhaps actually reflecting what the control does.

So here is my question.  Does the Range control on an EM extend the sweep width in BOTH directions at once?  In other words, when you increase the Range setting in flanger mode (Filter matrix will behave somewhat differently) does it sweep a little higher AND a little lower?  Or does it merely increase the sweep width more in one direction?

Mark, it sweeps lower as the range is increased. It's a few years since I fired up my old deluxe EM, and it does sound a litle week compared with the ADA - it has one or two rogue noises as well!

Did you get my pm the other day, I'm not sure if it was actually or not.

"Lower" in the sense that it increases delay time to produce more comb-filtering in the lower frequencies?

And yes, I did get your note.  Couldn't download the file you linked to from home, so I made a mental note to get to it on Monday and respond after seeing it.  Like all too many such mental notes, the mental magnet holding it to the refrigerator door of my mind must have slid and permitted the mental note to fall under the fridge.

Thanks so much for the schem and for thinking of me.  And no, I haven't spoken to him in several months.  I should do something about that.

[StephenGiles]

Indeed, lower in the sense that it increases delay time to produce more comb-filtering in the lower frequencies.

Funnily enough, my deluxe EM was in a box of EH pedals given to me back in 1980 or so by the lads at EH UK - I received a phone call that they were about to throw them away as unrepairable when I was working for their accountants. It probably cost Mike Matthews over £100 for my time to drive over from Croydon to collect them!
