Best Live Guitar Amp Microphones Buying Guide
Understanding Polar Patterns
The polar pattern determines how a microphone captures sound from different directions. For live guitar amps, cardioid and supercardioid patterns are preferred because they focus on the source directly in front of the capsule while rejecting sound from the sides and rear.
A tighter pattern, such as a supercardioid, offers superior isolation in loud environments, which is vital when multiple instruments are sharing a small stage. However, this requires more precise positioning to ensure the mic is perfectly aligned with the speaker's sweet spot.
Handling Sound Pressure Levels
Guitar amplifiers can produce extreme volume, which can cause cheaper microphones to clip or distort. It is crucial to select a microphone rated for high SPL (Sound Pressure Level) to ensure the signal remains clean even when the amp is pushed to its limits.
Dynamic microphones are generally more resilient in these high-volume applications compared to sensitive condenser mics, though modern condenser designs are increasingly capable of handling these pressures if they are specifically engineered for instrument miking.
Frequency Response and Tone Shaping
A microphone's frequency response curve defines how it colors the sound. Many microphones designed for guitar amps feature a presence boost in the upper-midrange, which helps the guitar cut through a mix by highlighting the attack and definition of the notes.
Flat response microphones provide a more neutral representation of the amp's tone, which can be beneficial if you prefer to do your EQ shaping at the mixing console. Consider whether you want a mic that adds character or one that acts as a transparent window to your amp's sound.
Placement and Mounting Options
The physical design of the microphone affects how easily it can be positioned against a speaker grille. Compact, low-profile microphones are often easier to place in tight spaces or on crowded stages where bulky stands might be knocked over.
Look for microphones that include or support specialized clips, such as goosenecks or cabinet clamps. These accessories allow for stable, repeatable placement, ensuring your sound remains consistent from soundcheck to the final song of the set.
Durability for the Road
Live sound equipment is subjected to frequent transport, setup, and teardown. A rugged, metal-housed microphone is a better long-term investment than a fragile unit, as it will withstand the bumps and vibrations inherent in touring or gigging.
Check for solid construction and reliable connectors. A microphone that is built to last will provide consistent performance night after night, saving you from the frustration of equipment failure during a performance.
Frequently Asked Questions
Do I need a condenser or dynamic microphone for my guitar amp?
Dynamic microphones are the industry standard for live guitar amps due to their durability and ability to handle high SPL. Condenser microphones are more sensitive and can provide more detail, but they are often better suited for studio environments unless specifically designed for high-volume stage use.
Where should I place the microphone on the speaker?
A common starting point is placing the microphone about one inch from the speaker grille, aimed at the edge of the dust cap. Moving the mic toward the center of the speaker cone typically increases brightness, while moving it toward the edge results in a warmer, darker tone.
What is the benefit of a supercardioid pattern?
A supercardioid pattern is more directional than a standard cardioid pattern. This provides better rejection of sound from the sides, which is very helpful in reducing feedback and preventing other instruments on stage from bleeding into your guitar track.
Do I need phantom power for these microphones?
Dynamic microphones like the Shure SM57 do not require phantom power. However, condenser microphones, such as the Behringer CB100, require 48V phantom power from your mixing console or audio interface to operate.
Can I use the same microphone for bass cabinets?
Yes, many microphones designed for guitar amps, such as the Superlux PRA628MKII, are also well-suited for bass cabinets. Ensure the microphone has a frequency response that extends low enough to capture the fundamental frequencies of the bass guitar.
