App Description
GtrEQ Guitar EQ & Buzz Kill (AUv3)
GtrEQ is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic Pro or GarageBand.
Overview
GtrEQ is a 5-band EQ / tone-shaping effect made specifically for guitar players, with the 5 bands focused across the frequency spectrum where the guitar typically lives. The peak / resonance of each band is also more gentle compared to general-purpose EQs, so adjacent bands are very "interactive". This makes GtrEQ well suited for overall guitar tone "sculpting", as opposed to the surgical precision needed for targeting specific frequencies.
GtrEQ also includes an optional "Buzz Kill" filter to help reduce mains hum noise. This buzzing can be a problem sometimes with single coil pickup guitars. Depending on your situation, GtrEQ might not be able to kill the buzz completely, but it should help reduce it significantly without impacting your original guitar tone too much.
Controls
Buzz Kill - Sets the target frequency of the mains hum noise filters which will depend on where you are in the world. For example, UK is 50Hz and US is 60Hz. Setting the control to Off will bypass the mains hum filters entirely.
Reduction - Sets how much attenuation is applied to the mains hum noise. Ideally, you want to set this control so the noise is no longer noticeable, or is at least at a "manageable" level. Buzz Kill processing has been designed so that the original guitar signal is impacted as little as possible, but you may notice a less "full" guitar tone when the Reduction amount is at maximum.
Buzz Kill processing, when enabled, occurs before the EQ section.
EQ - Switches the EQ On or Off. This is a "soft switch" so is well suited for automation / MIDI CC control if your host supports it.
EQ Bands - Sets a +/-12dB boost or cut for each of the labelled frequency bands. You can think of each band as affecting bass, low mids, high mids, treble and presence, but because of their interactivity, they don't work independently. You might be surprised by the range of tones you can get with just five bands!
Out - Applies a final stage gain trim to the output at the very end of the internal signal chain, between -24dB and +12dB.
Shameless plug alert... ANALOGyAMP
GtrEQ partners really well with ANALOGyAMP, a retro guitar amp simulator. Placing GtrEQ before ANALOGyAMP in the signal chain allows GtrEQ
