I don't know if it's common knowledge, but Warwick have stopped fitting Seymour Duncan Basslines preamps to Jazzman basses. I bought a Jazzman mail order on the basis of info on the dealer's price list and the Warwick manual that said the bass had a Basslines preamp. One of the things that made me order the Jazzman was that it had the Seymour Duncan pre-amp. It was more highly rated than MECs by users, plus it had the slap switch. When the bass arrived I realised that it had a MEC preamp. Rechecking the Warwick site I could see that besides the info about the Basslines preamp there was other stuff saying that the MEC preamp was standard I had assumed that this referred to an older version of the bass. I've emailed Warwick in Germany they say they changed to the MEC preamp from the time of the Frankfurt Musik Messe this year. They say they will find a way of resolving things to my satisfaction I gather they are usually pretty good about this sort of thing. However, I wondered how many other people on the forum knew of the change, and what people think about it.
