I have one instrument that has an odd note, out of sequence, at the top of the range. When I worked out pro-rata how much that note cost, I started writing tunes that used it, just to get my money’s worth.
Keep looking at that nice, flat space on top of the bulkhead and thinking the same – will have to start checking out the junk shops / eBay for a suitable box...
Would the price from your local company drop for a 'bulk' purchase - economies of scale, and all that?
And I do have pictures of a wooden box to fit under the parcel shelf, but have been told that there is not enough room for it on the current model. Have not peeked yet myself, either.
