Interesting take on using effects pedals. A lot of guys are using that Intramic which is a little water resistant mic that you put IN the neck of the sax, but non-destructively. A lot of horns in the 70s, they drilled out a hole in the neck and put in a pickup.
Anyhow, I’m not sure I like this pedals used in this video. Not really my cup of tea, but it’s interesting none the less.
