At first, I taught I've mistakenly bought an Acrolite. But after doin' some research, it was undoubtfully a Supraphonic. It is said that in 1984, when the Ludwig factory were moving from Chicago, they ran out of imperial lugs and decided to use the bowtie lugs instead.
Well, I removed the tone control knob, cuz I'll be using moongels instead. Made sure the drum head logo is at 12 o'clock, strainer at 9 o'clock and the butt plate at 3 o'clock.
However I need to get new snare wires. The buzzing won't stop no matter how much I try to balance the number of stands, just couldn't get them to tension equally. I'm looking forward to get meself them puresound brass blasters.
