Electric Mistress build report
« on: December 18, 2005, 08:54:19 AM »
My Second EM effort

It's a 9v version this time
This one is a bit different. 2 delay lines (each half of the 1024)
The first feeds the second (feedback signal) and Both mic with the original signal.

There is an extra fet output buffer for Unigain.
Besides that the endmix for both delay lines can be set with a trimpot (nice option).
Because of the tight buold I had some clocknoise problems. After hours of debugging (a headage with such a tight build) I found that shieling the wires to the rate pot takes care of clicking noises. (This also helps preventing click noises in bypass modus).

This buold sounds awfull with an Orange squeezer in front. I also use it on one of the rare coversongs we do (I'm the walrus).

Some experimenting


Top view


This looks like a spagheti experiment. Loads of wires



In the proces of building it into my pedalboard.

My god, that's a tight fit  !!!  ( said the actress to the bishop !! )
Why on earth did you want that in a 1590B ??  even 1590BB would be
tight !   :icon_lol:

....... I know , pedal board space  :icon_rolleyes:

Great work BTW !

Well the tight build has to do with my pedalboard. So indeed space on the board ;)
It's a flightcase I'm using for 16 years now. The top and bottom can be taken of. The botton cover contains the pedals.
Thats simply the space I'm allowing myself. (A bit of it can be seen in the top picture topleft)
This is because I'm also the lead vocalist and I like to switch while singing. So everything has to be real close.
Using these small boxes give me more processing in the small space.

I also found that tight builds have less noise, But that could be my mind playing tricks ;)

First of all, that's not a 1590B.  I picked up a couple of those boxes from Circuit Specialists a few years ago (at an unpleasant  price once shipping and broker charges got factored in), and wish I could get some more at a reasonable price.  I'm not sure of the part number or manufacturer, but they are just a bit bigger on all dimensions.  In fact, if there were no ribs along the sides, and the little corner bulges where the screws go in were removed, you could actually fit a 1590B inside them, with enough space to jiggle it around a bit.

The extra 8-10% of space, coupled with the option to split a circuit up unto several daughterboards held apart by the ribs, actually makes for a box thatcan accommodate a whole lot more circuitry.  For instance, the Heladito/Small Clone board I made from Francisco Pena's layout fits nicely into this box with a bit of extra board around the circuit, along with 3 pots and 3 toggles, and a little room to spare.  There is no way I could cram that into a 1590B. 

Funny how just an iddy biddy bit of space can make what's there much more usable.  It's like the difference between Volvo station wagons with that squarish end and sides, compared to those North American station wagons with their rounded ends and slanted sides.  Just losing that little bit of extra space because the part of the sides near the roof curve inward a bit makes everything below that tilt absolutely useless.

Second, kudos on the nice snug pedalboard.  Using these boxes and mounting the jack along the rear skirt has worked out nice and delivered a very compact and space-efficient pedal-board, judging from the upper left hand corner of the first picture.

Just a word of advice.  Steve Daniels sent me some of the "pre-bonded" wire he carries, recently.  The difference between the awkwardness of the 22AWG wire with the thick insulation that I had been using until now, and the suppleness with which connecting wires handle themselves using Steve's stuff is considerable.  It turns corners very easily and places less strain on the pot solder lugs when you have to bunch the wire in between the pots and board.  Given the tightness of the space you are confining yourself to, I highly recommend checking out this other wire, or whatever you can get that's like it.  You'll be able to stuff in way more stuff with fewer "packing" problems when the total diameter of wire plus insulation is reduced by 50%.

Good Lord, that's insane!  I thought I was a mastermind by sticking an Anderton Super Tone Control (with six knobs) in a 1590B--but I used external power.  Nice work!

Mark, et al: Have you looked at the Hammond 1590N1 (Mouser)?  It's just that 8-10% bigger than the 1590B that you mention.  Check it out--you may never go back to the "B" again. . . .    :icon_biggrin:

I like it!!

Btw that EVH pedal next to it, is that a DIY? Also I see a nice collection of rainbow boxes in the top left.

Is it quite flexible and can go from overpowering to v.subtle, or does have a sweet spot?

Hi

The fourth is the delay. Just aftrethe clock trimpot. Very nice extra
the EVH is a modded BSIABII. it has extra 3 band active tone.
and the rainbow.  ;) been building my pedal board. Build about 16 boxes up to now. Not al for stage use, but getting there

Will post the board when it's finished.
