There are also many different materials used for capacitors. A large portion of mass manufactured guitars come stock with a small ceramic disc caps. Many don’t use the tone control, so they never switch them out. However, for the serious tone-seeker, there are plenty of aftermarket caps available. Metal film, paper-in-oil, and polyesterfoil will each have a different effect on the overall tone of the guitar as well as the response of the tone control. Testing is useful to help find the capacitor that provides the right tone.
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.
Guitar - wah wah pedal - distortion pedal - pitch change pedal - amp - effects loop with chorus and reverb - speaker cabinet. The guitar cable should be long enough to walk around on stage with. But it should never be more than 25 feet in length, since it's an unbalanced cable* (longer lengths will degrade your sound quickly). Maybe 20 feet is a good length. However, since you have a floor pedal setup, you can use this to your advantage to shorten your cable length. Select a 10-15 foot cable for your guitar and a 10-15 foot cable for going from the floor pedals to the amp. That gives you 20-30 feet total, which is plenty for most live club circumstances. (If you have larger stage needs than that, look into wireless setups and balance boxes).
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.
