Electronics play a large part in the overall tone of an electric guitar and, as such, are the most commonly upgraded parts on the instrument. Pickups, potentiometers (pots), and tone capacitors (caps) can make a large difference in both tone and noise. If the guitar has mini potentiometers, upgrading for full size premium pots can lead to improved usability and audio quality. This will allow quicker and easier settings for a smoother taper of the volume and tone to achieve the desired sound – a reward worthy of the change.
JBL and Electro Voice. JBL and Electro Voice speakers are additional important American speakers. Unlike Jensens, JBL's and EV's are very powerful sounding (they have large voice coils and resonance frequencies around 50 Hz), and can handle a lot of volume. The JBL's were well known for their aluminum dust covers, and some of the early EV's came that way too (I think the purpose of the aluminum was to help extend the frequency response). The 12" JBL d120f's were famously paired with the Fender Twin Reverb for blues and jazz. The 15" JBL d130f was also a great speaker for the Vibroverb. Electro Voice speakers are mostly popular with heavy metal players. The original Mesa Boogie amplifiers were known for having a single EVM 12L speaker.
Guitar Wiring Explored – Introducing the Super Switch, Part 1. In the first part of this two-part article, we look at the original five-way switch and find it lacking for some uses. The 2-pole super-switch steps in to help, and we look at how we would go about wiring a Strat in the standard way using that switch. Once we’ve understood that, we go on to create an interesting alternate wiring scheme for a Strat that wouldn’t be possible with the standard 5-way.
The second common OEM tube out there is the Chinese Shuguang 12AX7 (Groove Tubes also sells this tube as the 12AX7C; Tube Amp Doctor has also sold this tube as a TAD 7025; and it has also been sold by Mesa Boogie). The Chinese 12ax7's are constructed with short, fat plates, like the Sovteks, but they have an extra spacer above the tubes, a big nickel colored brace connecting the plates, and a "halo" getter on top. Again, if you see a tube made like this, it's a Chinese tube, regardless of whether it has Groove Tubes or Mesa Boogie or TAD written on the glass. These tubes have a warmer tone than the Sovteks and more gain (volume). As a result, they work well in high gain amps.
