*Features diecast hoops.From the Canopus site:CANOPUS & the Zelkova Snare Drum Project The Zelkova hollowed snare drum is CANOPUS’ flagship model.  In the primary development process, we first experimented with traditional drum crafting theory.  Originally we cut the drum’s edge at an angle of 45 degrees on both the inside and outside of the drum’s shell.  Our first try was insufficient in resonance and was rather dull in regards to the drum’s sensitivity.We continued to experiment with several different edge angles. Including 70 & 60/60 degrees.  After our trial & errors, we finally completed an unprecedented edge shaping process.  The end result is a hand crafted snare drum with maximum resonance & a delicate yet fat sound with sharp response. (see figure) Our new edge shaping is very sharp. This overturns existing edge shaping theory. What we learned through comprehensive studies was in order to pull the best potential sound out of the drum, the edge shaping must be determined by the shell material, thickness & structure of the shell.  These lessons learned contributed to establish the framework for CANOPUS’ development policy.  These encounters have shaped our attitude towards the drum crafting process. Accordingly, when we are engaged in our drum & accessory development projects, we doubt the widely accepted drum production theory from the fundamental level.This is on sale on Craigs and Reverb for slightly less so the auction is subject to end at anytime.
