A tube guitar amp works with a bias voltage. This voltage is the difference between the cathode and the grid of a tube. By altering this voltage, you can control the operating point of a tube. This understanding is key to tube overdrive. You'll need to understand this voltage and how it relates to the signal.

Class A

The term "class A" is commonly used in advertisements for new guitar amps, but it's not always accurate. The term is a common misnomer, often used to mislead guitarists into believing that the product is higher quality than it really is. There are many different factors that determine whether or not an amp is classified as a Class A, and these are discussed in the following sections.

An essential characteristic of a true class-A tube guitar amp is its ability to run cool. This feature is crucial for producing high power without creating too much distortion. A true class-A amp will never sag or shut off completely. A typical Class-A guitar amp can run for several years before the power supply needs replacing.

A Class-A guitar amplifier's tone can be influenced by a number of factors. The type of speaker that's used, for example, can determine how loud an amp sounds. The Jensen P10T speaker is a classic example of this, offering a powerful and dynamic sound. The cabinet's bass response is full and deep and the transition from clean tone to full tube saturation is smooth. A slight tremolo effect is evident during the transition from clean to overdrive, and the tremolo is most noticeable when played at slower speeds.

While vacuum tubes tend to wear out naturally, it is important to know how to recognize the signs of a bad vacuum tube. Some signs of a bad vacuum tube include: an excessive amount of bass or low-quality sound, and discoloration of the valve glass cover.

EL34

An EL34 tube is a vintage design found in many guitar amplifiers. It has five elements, and is distinguished by its higher headroom and higher midrange. Its sound is versatile and well suited for a variety of styles, from blues to country to rock and metal. This tube is also known as the "American tone" and is perfect for both clean and high gain tones.

The most famous EL34 tube guitar amps were Marshall models, but many other companies have used this type of tube. EL34 tubes are often substituted with KT77 or 6CA7 tubes, which have similar pin-outs. If you're unsure of which to use, check the user's manual to see which one is best for you.

An EL34 tube is an ideal choice for many guitar amps, as it produces an even tone and high volume. Several manufacturers of EL34 tubes produce variations that are largely a matter of personal preference. Some are designed to reproduce the sound of certain tone types, while others have an entirely different sound.

A tube can be classified as an analogue or digital. For example, an EL34 tube is an ideal choice for a guitar amp with a high-quality digital signal processor. A guitar amplifier with a 6CA7 tube will have a more aggressive sound than an EL34, which has a clear midrange.

Marshall

If you're looking for an incredibly rich and authentic guitar sound, a Marshall tube amp may be the right choice for you. This legendary brand of amplifiers first gained a reputation among blues guitarists in the early '60s. Players such as Eric Clapton and Pete Townshend endorsed Marshall amps, and they have remained a favorite of blues players ever since.

This legendary amp is available in head and combo models. Both come with a 3-band EQ for versatility, as well as a presence control that allows you to tweak the top end. There's also a tilt control for blending the two preamp voicings, and a power switch.

It's not the most powerful tube guitar amp, but it's enough for home and rehearsal situations. The amp also comes with a convenient MIDI connection, which means you can plug in your mobile phone or a USB cable to play along with your recording equipment.

Vox

A Vox tube guitar amp delivers a warm and punchy sound. The VX-I model delivers 15 watts of power and the VX-II offers up to 30 watts. Both can be loud enough for playing with a drummer or for a small gig. Both are rated for a low price and have plenty of features.

Vox was started by guitarist Dick Denny, who was looking for a guitar amp with enough volume, sustain, and power to be heard in larger venues. In the early 60s, rock n' roll had started sweeping the world and the company needed to meet the demand. This led to the development of the AC30 amp, which had 4 inputs and two channels, including Normal and Vibrato.

The AC30CH uses four EL84 power tubes in the power section and three 12AX7 tubes for the preamp. This combo amp has a 16-ohm output jack and an external speaker jack. The AC30CH has an extra output jack for running through a 16-ohm cabinet.

Vox is a popular brand that dates back to the 1950s. It has a legendary status and is synonymous with the British invasion music movement. Since then, it has evolved into a global icon. Just about every famous musician has used a Vox amp. The Beatles, The Stone Temple Pilots, Paul Weller, and Hank Marvin are the obvious names. You can even find a couple of surprising bands using Vox amps today.

Stage Right

Although modern solid state and modeling amplifiers offer a wide array of tones and effects, most guitar players prefer a tube amp for its organic sound and warm, round tone. The SB20 head and SB12 combo amp from Stage Right deliver the classic tube tone and organic distortion that most players crave. Stage Right amps are perfect for guitar enthusiasts looking for a classic high gain tube tone.
