I have recently been watching many different videos about the GR55 and have the itch to get one. And as hard as I could, I searched for a specific thread addressing the question I have..... What Bass Manufacturers/Luthiers offer a bass in their collection that is Synth ready or offers an option of installing a Synth pickup for use with the GR55 or one of the other synth systems available for use with the Bass Guitar. I know of a couple that do, but I'm also looking for as many Manufacturers/Luthiers as I can so I can have many choices in purchasing a Bass that has this option. Again, I have looked and found many threads regarding the use of a Guitar/Bass Synth, different patches, and even installing a pickup on my own. So, if this has come up before, I apologize. Thank you for your help!
