There are many benefits of a tube guitar amp and they can be used to create a wide variety of sounds. However, vacuum tubes do wear out naturally. If you find your guitar amp making an unusually loud noise without plugging it in, it may be time to replace the vacuum tubes. The symptoms of a bad vacuum tube include a muddy sound, excessive bass, no clarity, or discoloration on the valve glass cover.
EL84 vacuum tube
The EL84 is a popular choice in British guitar amplifiers. This powerful tube has a focused beam sound with plenty of top end sparkle. It also has the ability to go from clean and mellow to aggressive and distorted. Typically, this tube is found in amps with 30 to 100 watts of power. However, the EL84 is also used in some smaller amplifiers.
Most contemporary guitar amp manufacturers use about half a dozen different types of output tubes. Four are used in great numbers: the 6L6GC, 6V6GT, EL84, and KT66. Some of these are more widely used than others. The EL84 is a popular choice, as it has great versatility and is affordable.
The Mullard EL84 tube has the lowest clean headroom of all EL84s, but it can be driven into distortion easily with aggressive playing. It has a softer and creamier overdrive than the other EL84 tubes, which makes it the ideal choice for blues players.
The power amp section of a guitar amp is what drives the guitar signal into the speaker. As a result, this section of the amp requires more power than the preamp. There are many different power tubes used in guitar amps, each with their own unique tone-shaping characteristics.
Jesse Hoff's J10LC

Its narrow panel and tweed finish add a distinctive look to this amp that's very much the stuff of retro vibes. Although this amp is a two-channel model, the normal channel doesn't sound like a normal channel at all. The guitar's volume controls the gain level and the tone of this amp.
The Jesse Hoff J10LC is a 10W, 1x12 combo that's one of the best-sounding tube guitar amps on the market. Its dynamic range is staggering, and the onboard effects make it a real treat to use. While this amplifier isn't cheap, it's worth the investment. It's a real gigging amp that's built to last.

Mesa Boogie JTM45
Mesa Boogie first made its name with the Boogie, a guitar amplifier that features a dual channel design and is named after guitarist Carlos Santana. It was originally a tube guitar amp but it was later redesigned with silicone diodes to produce a more natural sound. It quickly became a staple in the metal and hard rock scene. In fact, the Boogie became so popular that it has become a valuable collectible item, with some units going for as high as USD 70,000. Its most famous model is the Boogie Overdrive Special, which features two separate channels: a clean channel and a second overdrive channel. This amp is extremely flexible, allowing the player to tailor the sound to their preferences.
