I sure am enjoying my new hybrid Cleveland, but there are logistical challenges to playing such a cannon in an apartment building. I try to keep the neighbors happy. I've been taking this curvy brown companion down to the basement laundry room to practice. But even there, the ceilings are low, the space resonates -- certain notes really boom, and the lady in the apartment above suffers. On a whim, I tried covering over the ƒ holes with masking tape. WOW!! What a difference! 90% of the boom is gone. :^) And I can strike the balance I want by leaving some or none of the ƒ holes uncovered. Anyone else resorted to this? Cheers from the metro center of French Canada!
