I am going to build a road case for my Ashdown head and while I'm at it I figured I'd build a few more to sell if anyone is interested. I'll be building it to fit an Ashdown ABM-200, but the 300 and 500 are the same exact size. It will be pretty heavy duty.. 1" of ETHA foam all around, ball corners, 1/4 ply with ABS laminate, recessed latches, recessed handle. The case would essentially be a tray with a removable cover that would lock on with 4 recessed latches. My current design requires that the handle on the head be removed to fit the head in the case, but if you want to leave the handle on, I'm sure it can be accommodated via a cut-out in the foam. Priced at $175 (plus shipping). I'd like to see how many of you are interested before I order the supplies. Post a reply if you are seriously interested. Also, any suggestions in terms of the design/function of the case are welcome. Thanks.
