ah har, i like my kit, the 12" tom losses its tuning like every few days which is anoying, but the floor tom and bass drum are really sweet, and the snare is pretty nice sound when i changed the head and tuned it. It's compact and packs a punch, nice for mobility.
Hentex... I have a 12" tom for my Stage Custom. I have the same de-tuning thing.
I tune batter around 55 on the tama drum dial and reso around 70. I've found reso stays fine but the batter will drop.
I've been applying these lug locks to the batter rods.... fix the issue.
