I need to get a decent magnetic pickup for stupidly loud gigs I am doing with a ska band and am looking at the Biesele. I am also about to buy an AI Focus. I will be blengin the magnetic pickup with a Realist. Given the extensive blending capabilities of the Focus, I am wondering if there is any need (beyond what I can get out of the focus) to get the preamp that the Biesele pickup is paired with. Anyone out there with a Biesele that would care to comment?
