Electric Guitar Tone: Vacuum Tubes. Changing the vacum tubes in your guitar amplifier can change the tone just as much as changing the speakers. Many people claim the best 12ax7 preamp tubes and 6l6 power tubes are the American made RCA tubes that were produced in the 1950's and 60's, like the short, ribbed plate RCA 12ax7 and the black plate RCA 6l6GC, as well as the European made Mullard ECC83. Those tubes do sound great but they are expensive and dwindling in supply, since they are no longer being made. Fortunately, there are also a number of high quality current production tubes that are available to upgrade the tone of your amplifier.
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!
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.
If you want that same switching speed he is getting, you can still pull this off with your three-way pickup switch. Rather than set it at Treble, set it in the middle position (which is supposed to give you a blend of half Neck pickup, half Bridge pickup). Then switch quickly between the Rhythm position ("all the way up") and the middle position. That way you are not having to "jump over" the middle position in the switch to get the sound to cut in and out quickly. Jimi Hendrix and Van Halen are two of the best guitarists in rock history. What they have in common is this: the pursuit of new and unique sounds by trying all sorts of crazy stuff that other people simply wouldn't think to do. Hopefully this pickup selector switch trick I just showed you can spark some ideas for your creativity. Have fun!
