understanding pickup blend
So when you have a VVT wiring like a standard jazz bass, both pickups are at full when you turn them full up and you can turn any pickup as much up or down to your liking, simple to understand easy peasy!
But now how does it work with a "buffered" blend or the regular blend pot on most active eq preamps that we usually see which comes stock in a lot of basses today!
a. When the blend is at center are both pickups full on?
b. When i favor the blend pot 50% towards the bridge pickup! what is really happening now!?
1. is the bridge pickup output increasing over the bridge pickup out when the blend was at center position? (seems unlikely)
2. is the volume of the neck pickup being simply lowered by 50% and that is why i hear the bridge pickup more and the slight loss in the low end and volume which comes with lowering the output of the neck pickup in the bass?
c.When i turn the blend pot completely 100% towards the neck or the bridge pickup! what is happening now?
1. is the other unfavored pickup simply being taken out of the circuit?
2. is no output being dawn from the other unfavored pickup or no signal is being used from the unfavored pickup into the final signal?
3. is the FAVORED "ON" pickup somehow now sending double the juice when compared to the blend set at center (50-50) ??
(due to the active nature of the preamp?
too many questions? yes! :atoz:
But i hope am really being very clear about what am asking though! :help:
A proper blend pot functions as two ganged volume pots that sweep in opposite directions. At center both pickups will be full on. As you sweep from center to the bridge PUP, the level of the bridge PUP doesn't change, only the neck PUP signal is reduced. At the full bridge, the neck PUP is effectively removed from the circuit. In an ideal world...
There's interaction of the controls and the pickups affect each other in the real world, but essentially you're turning one pickup down when you sweep from the center to either extreme.
