i am not a Warwick expert. and i know that there are a lot of W freaks out there. here's the story. i found a Thumb bolt on 4 strings used on sale for 750 euros. i have some questions. 1. how can i find the serial number and year of manufacturing on this model? 2. i know that older ones are more respected than newer. when the warwick company started to "cut corners"? 3. i know that they changed the woods. when? 4. the pickup placement and control are the same on every thumb produced? are like these: 5.are the MEC pickups the same size of Bartolini, EMG jazz style aftermarket pickups? 6. can you please enlight me on the controls? there are 2 pickups and the bass actually produced is advertised as equipped with 2 bands MEc active EQ. but i see 3 knobs only. how does this control layout works? 7. how much are these new? and used? 8. at the same shop there is a Thumb NT on sale for 1280 Euros, used. can this big difference tell me something about the difference of the 2 basses? thanks warwick people!!
