Streamer PRO M is great. If you can get a Warwick Dolphin Pro I thats the one to get. www.basscentral.com has a very nice selection of Warwicks check them out.
You can get a Streamer stage II 4 string for that price from Matts Music ( www.mattsmusic.com ). I am thinking about one of those in my distant future and they had the best price. -KB
If you could find a deal on an Infinity model, I would heartily recommend it. I've got an Infinity 5 as my main fretted right now, it's phenomenal! Do you need to buy new, or could you shop used? You'll definitely get more bass for your $ if you could buy used... I also found the Streamer Jazzman to be a great instrument. ALmost got one of those... Nice contoured body, like the thumb, but better balance. Thumb's are pretty nice, but you have to deal with a monster stretch to the first fret, and they tend to neck-dive, but a whole bunch of pro's seem to rely on them... Are there any that you can try out locally?
I personally love the tone of the thumb model. Bolt on has a even chunkier tone to it but the NT (mine) has a more smooth tone to it, even the "junky" corvette standard is pretty good if you're on a budget the warwick i'd love to try and own is the dolphin model, but seeing that i'm a poor musician i'll probably never get one, unless I sell stuff....which i hate to do. man i wish i had a 2k budget to play with!!!!
The Warwick Thumb 4 is in my opinion the nicest bass they make. It does neck dive pretty bad when you strap it on and it is a bit of a reach to the first fret. It took me about three months to get used to it and now it is very comfortable. This bass is very well made and has a wonderfull rich tone. Although people are talking alot about the quality of the newer Warwicks, I compared my '98 Thumb neck-thru to a 2001 neck-thru and the only difference was the type of neck wood. The contstruction, craftsmanship and tone were all fantastic. I paid about $2000 for mine about two years ago. Good Luck!
Now you played the Warwick for $2000, $4000 & $1000. If you like the one for $1000, regardless of cost, isn't that the <i>"best if you only are willing to spend around 2000$?"</i> I'm not really familiar w/Warwick but the ones I've played & wouldn't take unless you gave it to me for free so I could sell them on eBay. Play as many Warwick's as you can & when you find the one you like, compare it to as many other bass companies you can so you know you're making the right choice. Good luck.
