Hello,
I’ve got pretty extensive experience using the H9000 as a hexaphonic processor, running 6 signals into it, one from each string, and I’d be happy to help with some detail here.
While I’m using a very different pickup than you, I am quite familiar with the GK-3 and GK-3b and might have some insight that is useful.
Indeed it is correct that you’d need to jump the cold pins together to make this work, but depending on the adaptor you are using that enables the independant outputs from the strings from the GK-3b, this may already be built into it. Are you building this cable or do you already have it built? are you perhaps using one of the commmercially available cable systems (like those made by Bill Bax?) or another breakout box? Or are you simply building a cable?. If the latter, where is your power and preamplification for the GK-3B signal coming from? Are you sending 7V for the GK-3B down your 13pin cable?
Just FYI – I definately find that the signal coming out of my Cycfi breakout box is a bit low for the H9000 and I need to set the H9K to -10db input. I know that the signal coming directly out of the GK-3b is signficantly lower and you may well have to amplify a bit more than will be provided by the GK3-B.
Those are my initial thoughts – But I’m happy to continue this here or on a private thread (it would be good to keep it public so others might search it out later).
