Stock strat pickups are 5.5k to 6.5k ohms. Tele lead pups are around 7k, stock Gibson humbuckers are also around 7-8k resistance. A lot of the new custom pickups are overwound to far beyond this, up to 10-14k. They sound like **** IMO but some people like to clobber the amp imputs.

I play live and record regularly with a guitarist with a
Pick-Up-The-World in his Martin, and it's far and away the most natural acoustic guitar sound via a pickup I've ever dealt with. D -- remove 555 from address to reply |

No, but I remember reading something in the marketing bumf for that guitar that said the knob was something to the effect of a "variable in/out-of-phase control" for two (or maybe more) of the pickup coils (each humbucker is split in certain of the switch positions on that guitar). I once tinkered with someone's AES800 with that in mind. I liked the effect you could get with the "subtle" knob turned about halfway. Very dry, cutting attack with a queer almost chorusy tone on what sustain was left. Seemed as if it would be ideal for funk. Raglan |

I'm trying to get a sense of what actually happens at the instrument-preamp
interface. --scott Guitar pickups are just like guitars, many factors will influence the way they interact with the preamp etc. The windings on vintage pickups are hand wound (irregular) and loosely packed, some pickups had wax or lacquer to reduce microphonics, magnet types vary from alnico II or V etc to ceramic, the cores vary. Being high impedance the pickups will be affected by the volume pot's dc resistance (250k or 500k) and the cable's capacitance and irregularity in shielding will cause losses/distortions etc. they are technically not ideal from a design standpoint, but the manufacturers that have tried to "correct" these faults with low impedance tightly wound buffered pickups have never really changed what most guitarists will look for in a pickup. A pickup is to be regarded as a musical instrument, for sanity's sake. Some guitar amps have a 100k resistor to ground that may pass through a decoupling cap before going into the grid, others have a 1 meg to ground and then a series 68K resistor to the grid. there are a lot of factors. The best all around input for a guitar is a high (2 meg and up) impedance input. this said some guitarists like to play with the volume on 9 (reduces high frequency resonant peak between pickup and capacitance of cable?) and some like long cords (cap. to ground via cable) some like low impedance transistor inputs... every guitar is different. |

Plus they affect the acoustic tone of the instrument; under the saddle is the worst possible place to put something soft like that, acoustically. I like the LR Baggs I-Beam. NOT a piezo.

I can tell you that Lance McCollum, using his own guitars, can install many different under-saddle pickups with sufficient excellence that even he can't be sure he hears a difference in the acoustic tone, and the guy has silly good ears for the sounds of acoustic string instruments. I like the LR Baggs I-Beam. NOT a piezo. Roll off a little low end and they sound very natural. And they are massive enough that they, too, must impose upon the response of the instrument. But yes, they're more natural sounding, sometimes. So far the best piezo antidote I've found, regardless of pickup maker or alleged quality of the pickup itself, is an Evil Twin DI. -- ha |

That that rig in advanced prototype, all properly packaged, at McQ's last year. Looked interesting, but so far I've not heard anybody say it sounds like an acoustic guitar, naturally. I played with it for a while at NAMM last Summer and couldn't get it to sound like anything but an acoustic guitar with a pickup. That was on headphones, but still kind of disappointing considering how much effort Taylor has put into guitars that, when amplified, still sound like guitars. But then I don't usually record the kind of music that people who play Taylor guitar play (showing some bias here, I know) but whenever I've heard someone play a Taylor I've often thought they'd sound better with some other guitar. At the AES show this year, I stopped by the Taylor/Neve booth and told the guy there what I thought of the amplified sound. He said he didn't have a problem with that - it was a guitar with a pickup. (which is how I described the sound) -- I'm really Mike Rivers ) However, until the spam goes away or Hell freezes over, lots of IP addresses are blocked from this system.
