Has anyone tried to make a three way 13 pin splitter using two US-20's  (will it work?) and/or is anyone interested in getting rid of a GKP-4?

[paults]

Someone offers a three way splitter, with on/off buttons, I think.  Try a site search.

You need an SGUS-3

Hi, thanks for the replies. sorry for originally posting in the vg99 section--i wasnt paying attention!  Awhile back i ordered an SGUS (freaking exspensive, by the way): it took two months to get here, with alot of "we are not sure where it is but we sent it" response to my polite email inquiries which i didnt start sending until a month had gone by (shipping was estimated at 25 days).  When it finally did arrive, it was D.O.A. (which to them was impossible/unbelievable)...i sent it back (it is made in europe, shipped out of germany, so shipping wasnt cheap). They said they would send me a new one if i sent the old one back. I replied i prefered a full refund. They said they would refund my return shipping if the unit was faulty...they never refunded my shipping. i guess it magically started working once they got it back!...i dont think i will try buying another one from over seas. So, Has anyone tried chaining two us-20's or is there a reason it wont work...does anyone want to get rid of a gkp-4? or get rid of a fully functioning SGUS from the united states? Thank for any help.

I have been doing research on this subject and have come up with this. Buy a manual rotary switch like the Manhattan data transfer switch.
They are a simple rotary switch with around 30 poles on them. buy 5 - 13 pin DIN female jacks and replace the jacks on the data switch. Do some soldering and you have a simple cheap switch that can be used either as a 1 into 4 or 4 into 1 switch. Depending on how you wired it you could even customize the configuration into something like GK into a,b or c and d together. You should be able to do this for around 50 clams. Also if you wanted to get 2 switches you could have 4 switchable GKs going into 4 switchable Roland units. The ultimate rig! The only down side is that these
switches are not foot switches. It doesn't matter to the basement musician like me but maybe to the live musician.

Here are some links for the switches. the jacks are harder to come by.

Use the DB15 or the DB25 I think. They have enough wires for the 13 pins.

You could use epoxy like JB Weld to fix the jacks to the case.

Many have adapted these type VGA Selector Box's for this purpose

For less than the cost of a 15pole, 4 way rotary switch, you can buy a Asian VGA selector box .

Then build  DIN 13pin to HD15 adapter cables.

Thanks for your inputs: Interesting idea with the computer junction box thing; is anyone out there using a homemade 13 pin splitter?  From the looks of the us-20's guts (resistors, capacitors, an IC chip and some things labed  "Q1,Q2,Qetc.")...it seems abit more comlex than simple wiring connectors/cables to a switch box. But i dont even solder, so good chance of it taking me forever and still not work!  I'd have to hire someone to build it and i am sure the end cost would equal or near-equal a roland factory built product...since i would prefer a 4way switch, the question regarding the chaining of us20's is mostly curiosity, partly a "plan B" if it will work and i cant find a gkp4, and partly an obsession to get an answer to a long unanswered question ( i began my inquiries on this matter about a year ago). It seems no one on the midi-guitar forum, this forum, and the gr30 forum has ever tried to chain the us-20's! I dont even know anyone in my town that has a us-20 that i can borrow!

[ericar123]

It's funny how forum topics get so off topic. I am sure that two us20s would work. The only thing a US20 won't do is work in reverse. You can only split 1 GK into many outputs. If you had 3 US20s then you would have 4 outputs and so on. Each additional US20 would add 1 more output. If I were you, I would ask some friends. Someone you know must have a little experience soldering. The computer switch thing will work for sure and is a cheaper way out. Good luck.

I will definitley look into the computer switchbox idea because i am curious to see if it will work. maybe, if nothing else, it'll be the impetus for me finally learning how to competently solder. thanks to all for your responses.

Well, in case anybody out there ever wants to know if it is possible to chain two US-20's together to create a 13 pin, three-way splitter: the answer is "yes" (at least it seems to be working so far!)...of course it works. why wouldnt it? i dont know, i guess i thought something would be internally voltage incompatible and i would burn out an expensive switching unit> why would i think that? i dont know: ignorance of all things electrical, probably. Not that my 'discovery' will make the world any better, but now i can cross that nagging question off my bucket list.
