@mosq You might be out of luck man, unless you’re willing to fork over a lot of cash. Eldorado is no longer available for purchase on the BFD Drums website, or 3rd party retailers. You can see this post here, where I linked a couple of options for someone else inquiring about Eldorado.
The eBay listing for BFD1 is reasonable, but you need to contact that seller and make absolutely sure that the serial# is not associated with any account. That’s the cheaper option. The other listing on Reverb, is for a new Eldorado, so there shouldn’t be an issue there, but it’s $149. So that, plus BFD3 is kind of a lot for some dated software, albeit pretty great sounding.
They really should make Eldorado accessible for those who want to experience the sounds of the OG BFD. It’s always fun to revisit those sounds.
