There doesn't seem to be much logic behind why Roland discontinue certain accessories without making alternatives available. The GR-55 manual and the Roland UK website both show the US-20 switcher as an optional accessory but when I contacted them to ask where I could get one from they told me they were no longer available. If that's the case then why show it?

(I was going to dig out my soldering iron and have a go at building a D.I.Y. US-20 unit but one came up on eBay UK complete with its short cables and I was the only bidder so that's one thing off the "wanted" list)

Were these GKP4 split-boxes massively expensive or were sales so low they just discontinued them?  I've often wondered the why this was the case but Roland being a huge company you figure something such as the parts necessary became unavailable or something else strange.

...although looking at those photos of it 'undressed', I am still yet to see anything that looks too expensive or unobtainable...    ???

Don't know what they cost new but just doing a quick search - a GKP-4 went for $272 last August on US eBay and the only one I've ever seen one on UK eBay was snapped up for a Buy It Now of £129 (approx. $205)

From the photos they do look like pretty simple and not something justifying a large price tag. All the components, including the 13 pin sockets, should be easily available.

They always seemed expensive to me, around $145 list/$125 street before they were discontinued. Seemed steep considering you only would need one if you had already purchased multiple GK toys. I understand limited production means higher unit cost to make a profit, but I held off buying it for years because it felt like Roland was saying "you can only get it from us, so we can overcharge as much a s we want".

The GK4P used to be affordable, but I understand that none have been manufactured since 2005, which is the year that Lead was banned from consumer electronics. Roland Corp decided not to produce a lead free version, and ceased production of the GK4P in 2005.
It's a case of short supply, high demand which has drove the price up.

10 years ago GK4P could be purchased for around $100, as it's essentially
five 13pin jacks wired in parallel, with voltage steering diodes to each 13 pin jack, and independent on/off selection of GK-SW and GK Volume per jack.

Hi,

Yeah the GKP4 is quite expensive for what it does.  I know the circuit back to front and inside out.  3/5 of the circuit is incorporated into my passive and active breakout box.

I've had plans to do a full GKP4 active breakout box, although the demand would be very low.  Even a four-unit v-synth distribution box alone would probably be over-kill aswell.  This is a tough one doin' it on the cheap.  Pricing...urgggh.

Regards,

Bill
