Ah OK thanks.
The Vbass is a great piece of kit - I use it as my pre-amp and as a monitoring system for IEM. I will be doing a little demo at the Bass Bash in October apparently!! Basically the Roland pickup (thin one at the bridge) knows the height of each string and it's length from the saddle to the nut. It then processes each string individually so you can play polyphonic synths, strings, effects and so on - and do amazingly accurate impressions of 'essential' basses like a Jazz or a Stingray. You can do this by essentially moving virtual pickups around the bass.
90% of the time I am playing clean with the magnetic pickups but when you feel like a bit of Marcus Miller, it's there, on a bass I enjoy playing more than anything else I have had.
Sorry, went on a bit there - but it is really hard to sum up such a comprehensive bit of kit otherwise! Since having it installed I have been completely blown away by it and have found that they actually have an impressive list of users such as Richard Bona and Leyland Sklar. Quite an undiscovered gem IMO!
Cheers
