I really can't confirm the price of/available options for the B6 when/if they start production. When the price was set at £1050 for the initial run, it was based on using Idigbo as the body wood. Doug found a source of quality swamp ash for only a bit more, and by means of apology for their completion being delayed (Doug was out of action for two months after breaking a couple of ribs in a motorbike accident), used that instead as he considers it a higher-quality tonewood. In all likelihood, any further B6s will also be made from swamp ash, but the price will reflect the upgrade, plus the fact that Doug mainly sources his woods from the US, so may have to increase his prices if the exchange rate doesn't get any better for us (though obviously the guitar will become less affordable for Americans by the same token).
Also, remember that many of the standard options on the custom models are optional extras on the B6 (camo covers, locking tuners, straplocks, coil-splitting). Any model of Bare Knuckle, Hauessel, Lundgren, DiMarzio, Seymour Duncan, or EMG is covered in the base cost though.
