Objet: Re: [Simmons Drums] Mystery SDS7 Module
I hate to to be the bearer of bad news but it'll cost more to repair this module than to buy one that already works. Jesper is right: the Curtis chips have been pulled and, maybe worse, so has the Hybrid board. You may be able to dig up the Curtis chips but the Hybrid is a whole other thing. :(
If you'd like to trade it against a working module, email me and we can work out the details.
