Hi Walter, I've used a few Sunrise pickups. They work well on the bigger, more heavily-braced guitars; Dreads, Jumbos, etc. They are relatively heavy and will kill a lightly-braced small top, like an F20 sized guitar (in my case, it was a '40's 'Banner' LG2 Gibson . They are magnetic pickups (humbucker), and will sound good with a magnetic pickup type guitar amp. Of course, they sound better with steel stings than bronze, etc.
I used to use them with fairly sophisticated preamps, and I never had much luck just plugging one in and winging away with it.
Again, they are fairly heavy and that helps with the damping process. I've seen a lot of name players with them and have kind of concluded that if you have a good sound-man who both likes and is used to Sunrise pickups, then they are a great pickup to have in the arsenal.
Don't leave it in the guitar when you travel. Sometimes they break loose and they will absolutely hammer the inside of your acoustic!
Luck, Harry
