I did it all. I bodged it all, but it works very nicely for what I want. It does not have earth moving LF, but extends down in a consistant way and that is good enough for me. I did a rehearsal tonight and carried my amp in like a heavy handbag. Happy days. I have not put any wadding in there amd probably will not cos once something is functioning I am usually too lazy to do amything else to it. But if I did, what would I buy off ebay?
TIA as ever.
