Thick old Remuna with just vestiges of the extensive old etching. The bowl was polished at some point and is very smooth to the touch. Clear penetrating soundscape, excellent harmony as the notes sing wonderfully together. There is some evolution to the sound over time, just fine for deep listening. Sustain is good. Excellent off the smooth rim if you are wanting overtone power. Such intensity!. Bass can also be played with leather smoothly but softly. With overtones at D#6, D7.
