I’d been hunting for these and had no joy contacting EBMM customer support either. Was super-pleased when I managed to pick a set of the pads up at the always brilliant Bass Direct in Leamington Spa, Warwickshire this morning as I’d gone in to buy something else and saw the full mute kits and the spare mute pads hanging on the wall. The chap told me he will be putting them on the website but hasn’t gotten to it yet. Sure if you email them he can sort it out though.
They are the genuine OEM parts and cost me £2.10 so I would presume it would be that plus a bit of P&P if you’re not local to the shop.
