QUOTE The problem with your initial premise - that you can cop any tone by fiddling with the controls on your vamp - is that the initial audio quality is set by the pickups (and bridge and nut and strings and hand pacement, etc ...) end quote agree but it's not a problem quote You cannot - cop a really good Jaco, using a P-Bass and a vamp. Ain't gona happen. No way. and no way are you going to take a J dialed in for bridge burp and make it sound like Conrad Lozano (Los Lobos - maybe the best rock bassist working today... if you don't believe me, listen - the man just has IT.) You can't take a Ric and make it sound like Paul on a Hofner or like Sting on his Steinberger - or the 54 for that matter. end quote never said anything about coping someone elses tone or technique. I only wish I could play as good as the legends listed. what I stated was I could make each of my basses sound like each other just by using my processor. one of which is a Warwick FNA Jazzman and of course a p-basse a jazz another p-bass and 2 douglas basses. quote You might not be intersted in those guys enough to get the nuances - but they are there. Pickups and pickup placement are a big part of the equation. end quote fat or thin mid boosted your choice it's acheivable.
