Casually I was asked about the harps I use on a forum today. I use almost all Golden Melodies. I have four Suzuki Firebreaths that I use as well. I have a lot of "backup" harps that are typically GM's, but I also have a set of Suzuki Bluesmasters and Lee Oskars.
I am an overblow player, so the reeds on the GM's are sweet. I like the out of the box feel of the FB's, but I've found I have to dampen the reeds to OB. On fast runs, there usually isn't an issue. If you listen to Leave Your Light On the end of my solo has a 6OB held with a "Chris Michalek" vibrato. I have a tricky time doing that on a FB without dampening.
I do take time to work on my harps. Tuning and reed replacement has been tricky, but I am getting better. I try to tune to 443khz. Draw reeds tend to flatten as you play, and the 443khz is what most my harps have been stock. I emboss, arc, and gap all the reeds, however, I've typically could get away with just tinkering with a few reeds.
When I play, I don't blow too many reeds...my harps last a long time. I think this has to do with breath control. I play some fast stuff from time to time and like to have the reeds be quick. I feel that my tone and playing is much better when I don't breathe with a lot of pressure. When I did the gig minus guitar, I noticed a huge difference in my technique. The air pressure I played with was an all time low, and it really made playing a lot smoother and toneful.
