Whatever LTD Warwick makes needs to be somewhat affordable (even though they charge in the $4000 range for their LTDs every year), so i imagine no vamp. Probably another thumb LTD, its been awhile, maybe a thumb with different woods or a maple fingerboard...
I don't think it needs to be "somewhat affordable". For a limited edition bass, I'm ok with it being high end and high price. It's a way to show off just what the company is capable of. A special insntrumebt shouldn't, in my mind as a marketer, be sitting in the similar range to run of the mill basses put out by the company.
I just bought my first Warwick (as well as my first 5 string bass), the Vamp SN and I find it amazing, the sound and the feeling of it. I need a bit of time though to get used to the 5th string and the stringspasing.
Can somene please recommend me a set of strings? I play in flat D (now A) and use mostly heavy gauge, always in steinless steel. I can not find many 5 strings sets in which is each string thicker than in medium set.
