This new style of pickup inadvertently gave birth to a new sound to guitars. The single coil pickup still is in wide use today. The single coil pickup has a cleaner or brighter sound. There is also less output on the single coil in comparison to its brother, the humbucker. The double coil or humbucking pickup tends to have more power and will have more bottom end or a bassier sound. Which pick is better is a matter of personal choice. Both of these picks have advantages and disadvantages.
Sovtek is the primary OEM supplier of preamp tubes today. Sovtek tubes are made in Russia. As you can see above, they have a spacer below the short, fat plates, a gap between the plates and the second upper spacer, and a "dimple" getter over the top. If you see a tube that looks like this, it's a Sovtek, regardless of the label. Sometimes they are marked as Sovtek 12AX7's but you also see them marked as Groove Tubes 12AX7-R's and Fender 12AX7's. You will also see them marked 12AX7 WA, WB or WC. I'm told the WB version has a little more gain and the WC version is a little quieter. Regardless, these tubes all have an edgy (bright) tone that is popular with Fender amp owners.
How Hum-Cancelling Works, Part 2. These two articles show us how me can manipulate coil winding direction, electrical phase, and magnetic polarity to achieve hum-cancellation between two coils. Having this knowledge allows us to create hum-cancelling combinations of coils over and above than just using humbuckers. A good example is using a RWRP pickup in the middle position of a Strat.
The key takeaway is this: when you are playing electric guitar, you are typically working with unbalanced cable runs. Unbalanced cables are fine. In fact, many super-expensive stereo systems use them. The key is that you do not want unbalanced cables to be too long. If the cable is too long, the signal can degrade and you can get extra noise on the line. The setup strategies I showed you above will keep your unbalanced cables at strategically short lengths, but still give you plenty of room to roam around on stage. Now go rock the house!
