If I was going after it, I'd use my Rick with thin gauge roundwounds that had been broken in. I think that would nail it pretty much on the money.
I know how this is Wally. For a long time, I've been trying to figure out the sound on the bassline to "The Avenue" by Bonafide on the "Royal Function" album. I know he is using a Steinberger through an Avalon, (the bassist told me in an e-mail). But I can't nail it live. Any guesses can be taken at
www.cdnow.com where they have a sample.
