But at the same time, a Vox just has too much of a different sound than a Fender, and a Boogie, especially with its EQ, has a different sound than a Marshall (although ACTUALLY, the Helix does have Mesa’s EQ in a block, so I may need to think more on that lol). These differences need to be accounted for if you’re doing covers and want to do them as accurately as possible, in my opinion.
This is key. Do you really want to do them as accurately as possible, including the exact guitar tones? If I were playing in a tribute band, most definitely so; but then for Queen I'd need just one Vox amp and corresponding IR. In a cover band I like to play the music as close as possible to the original, including note-for-note solos when I can pull it off (unless we come up with our own take on the song, which is also fun), but I do not feel like I have to replicate the same
sound as long as the sound I use works for the song. I think with many different songs with various effects this creates a sonic mishmash that may be confusing. The way I look at it is: I want the band to have
our own sound, and to adapt that sound to the songs we play. Most of all, I want the band to sound
good, and I think this is more easily achieved with some sonic consistency. Nothing wrong with other approaches, but this way it feels easier for me.
For compressors, reverbs and so on, IMO it is very much style or song dependent. Sadites' end-of-chain compression and other tricks never worked for me "as is", but often I do somilar things in different ways; for example, I like some sag in the amp, which is also a form of compression. Whatever works for you. For me, compression blocks are too sensitive to the threshold values, so that I need a different threshold for every guitar or I'll feel the amount of compression is always wrong, and that's a mess. Reverb I use very sparingly live, or not at all (unless it
must be a very obvious effect), because it puts me back in the mix and the Lord knows the other band mates have trouble managing their volume... Same for compression and modulations. But this is for classic rock, and other genres do need different choices.
