I have used humidipaks for years without any problems. I've also recharged them in a manner described elsewhere, without problems. So I am an advocate for this system to maintain the proper humidity in my instruments. That said, I do not like and cannot figure out how to effectively use the "new and improved" center pouch method that's being shipped now from big retailers. (Note: Nearly all retailers I checked online still advertised the old box with the "old" double center pouch. I ordered from a retailer named after a rain forest and received the new system).
So, instead of the double pouch method that inserts simply on the sound hole sides of the upper and lower E strings, the new system has one pouch into which you're supposed to insert two humidipaks then seal with two plastic pieces. The instructions then tell you to insert the pouch between the D and G strings.
I followed the directions. After some effort I managed to get two humidipaks into this new single pouch and to secure the top with the two interlocking pieces of plastic. I carefully separated the D and G strings and slid the pack into the belly of the guitar. My new 614ce is a grand auditorium. No matter how I adjust the plastic devices the pouch sits on the bottom of the guitar and the plastic pieces are free to move around and rub against the finish of my new guitar.
The literature claims that the pouch is less likely to permit leakage, but I don't understand why they couldn't have used the same material for the double pouch system?? Since I couldn't trust online vendors to ship what was pictured, I went to a local store and bought the old system.
Has anyone else tried this new single pouch sound-hole system. Am I missing something?
Cheers,
Bill
