OK so i am really into synthesizers and i want to use my bass guitar to play one right, but not just one specific synth but all synths that have a midi port. I know i could just learn to play keyboards, but meh, i really like seeing peoples eyes going crazy wondering which instrument is playing the synthy stuff, even though there is no keyboard. So in order to do this I have heard good stuff about the Roland g synth bass series, but they are pretty expensive (but if push came to shove I would be willing to pay) and they are old so if something goes wrong i might not be able to find anybody who could fix it. But now i am hearing of this Roland GK3B Bass Synth Pickup. So now I want to know exactly what this is, how it works, if its good, and could i use it to play on any synth with midi capabilities?
