“Heads,” “cabinets,” and “combos” are terms used to describe different components of an amplifier setup for electric guitars.
Heads
A “head” is the amplifier unit of an electric guitar setup that contains the electronic circuits that amplify the guitar’s signal. The head usually does not include a speaker, and its purpose is to amplify the signal, which is then sent to a separate speaker cabinet. The head also typically includes a set of controls for adjusting the amplifier’s tone, such as bass, midrange, treble, and gain.
Cabinets
A “cabinet” is a speaker unit that is used in conjunction with a head to produce sound. The cabinet contains one or more speakers that receive the amplified signal from the head and convert it into sound. Cabinet sizes and designs can vary, and they can have a significant impact on the overall tone and character of the sound produced by the amplifier.
Combos
A “combo” is an amplifier unit that combines both the head and cabinet into a single unit. This means that the amplifier and speakers are all contained in one box, making combos a more convenient and portable option than separate heads and cabinets. Combos also typically include a set of controls for adjusting the amplifier’s tone, as well as the volume of the speaker. Combos can come in a variety of sizes and configurations, and they are a popular choice for small to medium-sized gigs or practice sessions.
Advantages of using a combo unit:
- Portability: Combos are more portable than separate units since they are contained in a single unit. This makes it easier to transport to gigs, rehearsals, and performances.
- Cost: Combos are usually less expensive than separate units since they do not require the purchase of separate head and cabinet units.
- Convenience: Combos are more convenient to set up and use, as there is no need to connect separate head and cabinet units together.
Disadvantages of using a combo unit:
- Limited customization: Combos do not allow as much customization as separate units. For example, if a player wants to use a different cabinet with the head, they cannot do so with a combo.
- Upgradability: Combos may be less upgradable than separate units since they are usually designed to work together. This means that if a player wants to upgrade the head or cabinet, they may need to replace the entire combo unit.
- Sound quality: Combos may have a more limited sound quality than separate units, as they are designed to work together in a specific way. A player may not be able to achieve the same level of sound quality and tone shaping options as they would with separate head and cabinet units.
Ultimately, the choice between using a combo unit or separate units will depend on the player’s needs, preferences, and budget. Combos are more convenient and portable, while separate units offer more customization and upgrade options. Both options have their own advantages and disadvantages, and it is up to the player to decide which option is best for them.
