I've had another good play of this enigmatic 64 Supra with COB hoops.
The current setup:
Coated Ambassador batter
RMV snare side (they're cheap here!)
Gibraltar generic wires
After suitably hammering it for an hour, I am actually starting to hear the Supra-ness come through. The thing about these hoops is that they are VERY DEEP, so rimshots are quite fat and pentrating. I tuned it up a bit and that familar Supra 'pop' is coming through; just a little darker. Indeed, as O-Rings says, it could be a case of apple and oranges.
Not to say I reneg on my original criticism of this drum, but is it possible that this drum needs to just be really PLAYED to warm it up? This is something I've noticed with my brand new Ludwig Classic Maples, including a Legacy Snare. After 6 months of playing, they are sounding, perhaps, rounder with more focussed tone. Am I sounding like a wanker? Am I deluded? Is this phenomenon the reason why we love vintage gear - because it has all been played in?
A colleague of mine, a great double-bassist named Frank Disario, bought his dream bass. In describing it, he said that the neck felt amazing, because it had the proverbial sh*t played out of it (sic), having been previously owned by a classical player. Can this also be true of vintage gear?
Perhaps the subject of another thread...
Thanks again for everyone's very helpful perspectives and responses.
