"Dimed" is an adjective used in slang, particularly within the context of music and audio equipment, to describe an electric guitar or its amplifier being set at its maximum volume, typically indicated by a '10' on the volume dial.
Understanding "Dimed" in Audio Equipment
The term "dimed" originates from the common practice of marking volume knobs on amplifiers and other audio gear with numbers, often from 0 to 10. When an amplifier is "dimed," it means the volume control has been turned all the way up to its highest setting – '10' – resulting in the loudest possible output from that specific device.
This setting isn't just about loudness; it often significantly impacts the tone and character of the sound, especially with tube amplifiers.
Why Musicians "Dime" Their Amplifiers
Musicians, particularly guitarists, "dime" their amplifiers for several reasons beyond simply achieving maximum volume:
- Achieving Natural Overdrive and Distortion: Many tube amplifiers are designed to produce a rich, harmonic overdrive or distortion when pushed to their limits. This natural "breakup" of the sound is highly sought after in genres like rock, blues, and metal, contributing to a warmer, thicker, and more sustained tone.
- Maximum Presence and Impact: In live performance settings, especially without extensive PA system support or when competing with loud drums and other instruments, diming an amplifier ensures the guitar cuts through the mix with maximum presence.
- Historical Tone Replication: Many iconic guitar tones from the early days of rock and roll and blues were achieved by simply turning up relatively low-wattage amplifiers all the way, as sophisticated distortion pedals were not yet widely available.
- Expressive Dynamics: Some players use the dimed setting as a base for their sound, then control dynamics and further breakup using their guitar's volume knob or playing dynamics.
Characteristics of a Dimed Amplifier
When an amplifier is "dimed," several audible and physical characteristics may become apparent:
| Characteristic | Description Size/Weight: These factors are crucial for portability and the practicality of transporting the equipment. For instance, smaller, lighter amplifiers are more convenient for solo practice or smaller gigs, while larger, heavier models might offer more expansive tone.
- Power Output: The power output of an amplifier dictates its maximum clean headroom and how it interacts with speakers. Higher wattage typically means more volume before distortion, though the relationship isn.t always linear. Tube amplifiers often sound louder than solid-state amps of equivalent wattage.
- Tone and Features: Every amplifier has a unique voice. Factors like the type of tubes (if applicable), speaker configuration, and built-in effects (reverb, tremolo, etc.) shape the tonal characteristics. Some amps excel at clean tones, others at crunchy overdrive, and some are versatile.
- Cost: Amplifier prices vary widely based on brand, wattage, components, and features. It's essential to consider your budget while balancing desired features and sound quality.
A well-known example of an amplifier often "dimed" for its signature sound is the classic Marshall JCM800 or Plexi series, famed for their raw, powerful rock tones when cranked to the max.
Practical Considerations for Diming an Amp
While "diming" an amplifier can yield powerful and desirable tones, there are practical considerations:
- Volume Levels: The sheer volume can be excessive for small venues, home practice, or even large stages with sensitive sound engineers. Hearing protection is crucial.
- Tube Wear: Regularly running a tube amp at full capacity can accelerate tube wear, requiring more frequent replacement.
- Speaker Stress: Pushing an amplifier to its absolute maximum can put stress on the speakers, potentially leading to damage if the speakers are under-rated for the amp's output.
- Feedback: At very high volumes, unwanted acoustic feedback can become an issue, especially with hollow-body guitars or insufficient stage monitoring.
Guitarists often seek solutions like attenuators to achieve the "dimed" tone at lower, more manageable volumes. An attenuator sits between the amp's output and the speaker, allowing the amp's power section to be pushed hard for tone, while reducing the overall volume.
