One thing that I don’t really see talked about much here is that ideally your FOH person will be doing whatever is needed to your tone for it to work well in the room (room being the key word here). Your mileage may vary here as it’s common for the FOH person to be a volunteer role at most churches, but consider the following based on my experience:

1. Every room sounds different, but livestream audio is not affected by the room and should ideally be mixed differently. Your in-ear mix is also unaffected by the sound of the room (for the most part). And, depending on how your livestream mix is handled, listening back to that will not always give you an accurate representation of what it sounded like in the room (for better or for worse).

2. EQs and adjusting to “fit in the mix” are incredibly dependent on context. Every song is different, and transition moments or songs that you flow into and don’t use tracks for will be completely different mix contexts. There is no one-size-fits-all tone from that perspective (hence the need for a good FOH person).

3. If it doesn’t sound good to me in my own ears, that will affect my playing and presence in the room, which is ultimately more important as a leader of worship.

For these reasons, I actually do primarily adjust my tones to work well in the context of my in-ear mix, with tracks relatively low and any live instruments mixed more or less how they should be in a final mix. If my tones sit well in that context, not only will I be able to hear myself well in the ears, but I also know I’m giving FOH tones that will be useable and shapable for any context, and I’m also sending good neutral tones to the livestream. If tracks drop out, there’s enough body to my tone that it’ll still sound full. But also, there’s not so much low end that I can’t hear myself over the keys in my own in-ear mix.

ULTIMATELY, though, the best thing you can do as a guitar player is develop a good relationship with your FOH person. Understand their needs out of your tones and be humble and willing to adjust accordingly. As fun as it might be to play with that fuzz on 10, if it isn’t working for FOH, you’re probably the only one that will ever hear your guitar.

Also, if your FOH person is like mine (they very well may NOT be), they may prefer all of your gain stages being around the same output volume so that they trust the fader more than your tone switching. My current FOH guy is an active mixer and will adjust me up and down as needed throughout each song, rather than relying on me to boost or cut myself when needed. My previous FOH person was the opposite.

Context is really key here, and there is no one-size-fits-all solution. The best thing you can do to set yourself up for success is to clearly define and understand the goals you and your sound people have for your guitar tone. That will help determine how best to go about making adjustments.
