My father have owned at least 25 Acrolites over the years. The Black Galaxy drum was, as posted above, made in the black and white badge era. They are available in 5.5 and 6.5 inch. To me, the keystone, gray annodized and black drums all sound very different. The keystone drums are in my opionion by far the best sounding acrolite snare and maybe the best sounding Ludwig metal drum. I personally would pay up to $225 for a mint keystone acro. I would not pay over $80 for either of the other 5.5 inch models. I would go up to $150 on a 6.5 black galaxy drum.
All acrolite snare have internal mufflers. Through ’69 they had baseball bats, past then screw tension. Blackrolite 6.5″ drums are quite nice and very boisterous if you want depth as well as crack, but the simple 5×14″ original Acrolite design is so modular that you can probably find the tone you’re looking for iwth propper heads. I have a ’66, a ’69, and a ’72. Honestly, all three sound about the same to me. I like the looks of the two 60′s Keystone drums better as they have a more natural satin aluminum finish versus the grey finish of the 70′s model. The 70′s B/O drums, however, are cheaper, generally in better condition for the dollar, and more adjustable with the thumbscrew tone knob. I would consider upgrading the P85 throwoff to a P86 which is expensive but worth it if you can find a good deal on the drum. I really like a Remo Vintage Emperor on my Acros right now and can give it subtle dampening with the tone control if needed. As for snarewire, Pearl’s pro snarewire is the best way to go for just about any drum, especially Acros which generally need snare cord as opposed to plastic tabs.
