When connecting your electric guitar to an amplifier, you may come across terms like “high input” and “low input.” These inputs on guitar amps are designed to accommodate different signal levels and instrument types. In this article, we will explore the differences between high input and low input on guitar amps, helping you understand their purposes and how to choose the appropriate input for your setup.
Understanding High Input and Low Input:
- High Input: The high input on a guitar amp is typically intended for guitars with passive pickups, which generate a lower output signal. This input is suitable for most standard electric guitars. It provides a higher level of amplification, compensating for the lower output signal of passive pickups. The high input can be useful if you want to drive the amp harder or achieve a more distorted tone by pushing the input stage of the amplifier.
- Low Input: The low input on a guitar amp is designed for instruments with active pickups or instruments that already have a higher output signal. Active pickups have a built-in preamp that boosts the signal level, resulting in a stronger output. The low input accommodates this higher signal level without overdriving the amp’s input stage. If your guitar has active pickups or an exceptionally hot output, using the low input can help prevent excessive distortion or clipping.
Choosing the Right Input:
When deciding between the high input and low input on your guitar amp, consider the following factors:
- Guitar and Pickup Type: Determine whether your guitar has passive or active pickups. Passive pickups generally work well with the high input, while active pickups may benefit from using the low input.
- Desired Tone: If you prefer a cleaner, more balanced tone with less distortion, using the low input can help maintain clarity, especially if you have a guitar with high-output pickups. Conversely, if you want to push the amp’s input stage for more overdrive or distortion, the high input may be a better choice.
- Experimentation: Don’t be afraid to experiment with both inputs to find the sound that suits your playing style and musical preferences. The interaction between your guitar, pickups, and amplifier can yield unique tonal characteristics, and trying different combinations can lead to interesting sonic results.
It’s important to note that the specific labeling and functionality of inputs may vary between different guitar amps. Some amps may use different terminology, such as “normal” and “bright” inputs, but the underlying concept remains similar.
Understanding the difference between high input and low input on a guitar amp is essential for optimizing your tone and getting the most out of your instrument. The high input is designed for guitars with passive pickups, offering increased amplification for lower-output signals. The low input is suitable for guitars with active pickups or instruments with higher-output signals, preventing overdriving or excessive distortion. Experimentation and personal preference play a role in determining the best input for your setup. Ultimately, choosing the appropriate input allows you to achieve the desired tone and unleash the full potential of your guitar and amplifier combination.
