More resonant than regular REMOs on this drum which has the "cut for calf" bearing edges. The tuning range has increased (especially in the low end) but this drum has a definite sweet spot.
FYI The REMO's inside diameter is 1/16 inch larger than the Aquarian American Vintage.
Got the 12" installed, tensioned and balanced with the FT. I'm very pleased and plan to install the AAV Thins on the reso side before buying more REMOs.
