I have a hard case shell for my bass drum - I recently broke the plastic fastener that interlocks with a male/female type buckle that holds the strap firmly around the case for transport.
I have tried to get a replacement buckle/fastener to adhere the existing case strap around the bass drum case. Not so easy!
Went to my local repair guy - he had a replacement buckle but it was too big for the strap - I called my music store - they say they can get a replacement buckle for $40 but it wont be available for two months - too expensive and too far away...
Went to my local travel bag store - they had a similar strap with a similar buckle but the strap was too wide - however as I write this I realize I could simply buy the strap for the buckle portion assuming it can be applied to my strap!
How ironic I think I've got my answer by writing this blog! Has anyone ever had this dilemma? If so how did u solve it?
