Hi All, I need some advice from those of you familiar with Warwicks. I am an old Fender player from way back. I played the same '74 Fender Jazz Bass for about 20 years until I had a garage break-in about 3 years ago where all of my gear was stolen. I'm finally now getting back into it and wanted to try something fresh. I was able to get a great deal on a new Warwick FNA Jazzman 4-string from Sam Ash so I bought it. It's a great bass...lots of different tones...it is set up very nicely with a semi-light action, I can get a very rich, deep tone out of it. I love it except for one thing...I can't seem to get that Warwick "growl" out of it. Sometimes I think I may have bought it because the price was so good (and the guy watching me try it out said it sounded hot). Maybe I'm just thinking about it too much. Maybe I have to set it differently to get it to "growl". Maybe I'm just being too anal but I have to decide quickly in case I want to trade it in without losing any money. I tried out a Warwick Thumb Bass and there was that "growl" I like. I play classic rock, blues, jazz, lots of scales but I am not a slapper. I use my fingers exclusively. Ok, here's the question...Should I keep my FNA Jazzman or trade it and $300.00 more dollars for a Thumb? I haven't tried out the Thumb enough to see if it is versatile. I do like it's growl but will I get tired of it? Please help with opinions and insight. Thanks in advance.
