Hey guys, I'm working on building my second Eub and I want to get a little more advanced with the electronics. On my first bass I have the fishman b-100 going straight into my hartke head > nemesis 4 x 10, and it actually sounds pretty good. But i really like the sound when i run it through my friends outboard fishman preamp. So, for my second eub i would like to have an onboard preamp. Simple is good. I would like just a volume control, or no controls at all & it needs to be able to handle a two piezo set up like the b-100 or the double big twin. I am aware of small outboards like the K&K compact & so forth, but I really want something i can mount internally in a small rear routed control cavity. Does anybody know of anything like this that is commercially available?
