In my twenties, a while ago, I had a fantastic Gretsch kit, I sold it because I was a bit hard-up, it is one of the dummest things I ever did!
However I bought a used (4piece compact) Premier vintage Jazz kit.
The hardware on that kit (from the 70ties) does not look much, compared to modern standards it is a bit spindly, the quality though is super, and because the lugs are quite small there is not a lot of "interference area" on the shells.
You do not need a drum key on this set because it has a groove (slot) on top of the tensioning rods where you can put a screwdriver or a small coin!! to purpose.
The shells (birch) are superb, especially the snare.
I was thinking about upgrading but to have something better I have to go to real expensive pro-stuff.
So i keep smothering my set in baby oil, and have the right heads on them and be happy about it.
I also have a set of nice Meinl fibre-glass Conga's for my Latin exploits, I just painted them (professionally) metallic racing green, Like Simon Phillps's (my favourite Drum Hero) Tama kit.
Happy Drumming and cheers,
Harry
