Bear with me here...
Last summer I stumbled into a project with some players who were very successful in the 80's, playing with and writing grammy nominated gold-record songs for a who's-who of talent in what would now be considered Classic Rock. There are even MTV videos.
Pros and Tone: In our very first informal jam, the guitarist was playing a Strat through a tiny Roland car battery amp, no effects other than an on-board delay. I was absolutely gobsmacked with the different tones she was able to get, just with technique. She has a pedalboard for gigs, but it's kind of a set-it-and-forget-it type situation.
Fast forward to yesterday, and we played for about 4 hours with the lead guitarist/founder of another big group from the late 70's/80's that is touring again (I listened to this group to the point of annoyance in High School so it was quite the thrill). He played a little Soldano amp our guitarist had sitting around, and his pedals consisted of a Boss Chorus Ensemble and a tuner, with some grit on the amp. Period. Again, he was getting all these wildly different tones without really changing any settings other than on the guitar. Our guitarist was on the Roland and doing the same thing. I have never been a huge fan of Les Paul tones in general, but without all the effects, I could really hear the nuances of it and it was truly eye opening. This is all at a pretty low volume as well (muted drums).
Previous bands and Tone: Before this, I was in a procession of local bands from Country to Classic Rock covers to some originals. 99% of the guitarists I played with had pedalboards with at least 10 effects in them, but all close to $1000 worth of pedals. Every guitar and every song sounded the exact same. In some cases, the guitarist actually missed half his solo because he was trying to get the right pedals on and off.
Pros and Writing: We were arranging and rehearsing some songs they had written together in the early 80's before the demise of their band, so I got a front row seat at their process of arranging (I shut my mouth and watched/learned). What I found interesting is that their focus was on what each was playing in regard to how it sounded with the other guitar part. Once riff would inspire another, which would inspire another and I could hear them molding the song into shape. They knew pretty quickly when they got off track or went down a rabbit hole and would stop, sometimes going back to close to what they had originally. But it just sounded right because they figured it out to be best for both guitars. WHile they requested certain things from bass and drums, it was neither an order nor a wishy-washy request. Always very supportive.
Previous bands and writing: Guitarist - "I'm playing this. Play whatever you want." End of arranging. Or when helping to write a song "I think this sounds better". End of writing input.
The only commonality is that neither guitarist I'm with now, nor the previous band ones can read or write music. While the Pros certainly know chords structures and keys and things like that, it's all ear and feel. It's a constant learning process as opposed to learning a song one way and never changing it.
Sorry for the long blather, but this experience has really been an eye-opener for me and I had to get it out. I'm wondering if this is an isolated case or if others have been in a similar situation and noticed. Gotta say, it has taken my playing and approach to a different place. I've never been as relaxed on stage as I am with this band. Maybe it's because I don't have to worry about they're doing?
