I enjoyed the article. Thanks for that.
Regarding pick-up systems for acoustic guitars. There are many professionals out there today using multiple systems and mixing them together. That way they get the most out of each system and a more "natural" (for want of a better word) acoustic sound.
I very recently saw the australian singer/songwriter Derrin Nauendorf play in a very small location using the house system. I'd played there 4 days previously using my Model II. After hearing their system I would possibly opt for not carrying more gear than necessary and also use their system.
During the gig I was impressed by his guitar sound. I could see that he had 2 cables connected to his guitar. After the gig we talked to each other on the stage. Could see 2 DI boxes each with a cable + the 2 cables from his guitar and asked him how he got his sound. He told me this:
The guitar has a transducer system (the guitar was a yamaha I didn't ask which model) which he twinned with a rare earth magnetic sound hole pick up. Each pick-up has its own output jack on the guitar. Then out with 2 cables each to its own DI box and then directly into the house mixer. He used nothing else to enhance his sound (a touch of reverb perhaps to give the guitar a touch more "room") just the EQ in the mixer. Nothing special. The sound was really good. He said he was thinking of maybe putting in a third system to give him even more scope of mixing a good sound together.
