It's cool... I do totally get what you are both saying.
You deal with hired musicians in professional studio environments paying by the hour etc all the time.
My questions (as always) are directed toward the small scale guys working in less than full quality studios, not at the professional level you work with but still trying to get a level of understanding in place for the 'average Joes' out there who may be doing this for the first time and have not gone in with a succinct level of understanding in regard to frequency and bandwidth.
While that lack of knowledge will frustrate a professional, the player still needs to be able to understand why changes have been made to what they did to make it sound so very different. They have the right to approach and ask.
If I play a part, or god forgive a repeat of the example where it was MY song, and the engineer changed it on me... then I want to know why.
The background to this one:
Six local bands chipped in for a compilation recording... 3 songs each, mixed and released on cassettes, each band getting an equal share of units from the production run. We all paid the same amount and it was up to us to put them on consignment in local record stores. The engineer was the uncle of one band's bass player, so all communication was coordinated through that band. When I got the proof version of the final recordings, every song by every band sounded as they did live, except ONE of our band's songs, particularly my guitar parts, had been flooded with effects in post and they sounded alien to my ears. We had been performing that song live for years and it was a song my audience knew, and this production was not an "add value", it changed the feel of the song.
So I called the band in charge, told them about this. They said he knew what he was doing. The song was not going to be changed. No consultation.
Yes, it was a long time ago for me, and water under the bridge etc etc... but my post was to state that young/ new players getting stuff recorded should be able to ask why their efforts are changed, with the people making the changes having enough understanding of both the industry and the people they are working for/ with, to take the time to explain WHY it was done.
