Now it seems a little confusing as to what you can do with these - is there a clear explanation (like a policy document) anywhere, so that I can try and understand the system?
Ah, you need the books "IK Multimedia Marketing for Dummies, Vols. 1-3" which explain how to navigate the labyrinth that is the IK shop. All your questions about Credits, Jam Points, Group Buys, Custom Shops, Bundles, Expansions, License Transfers and all the other mysterious IK concepts you may be wondering about are laid out in exacting detail. Complete with pages and pages of charts and graphs showing how to hit that elusive "sweet spot" where you maximize the value of your IK purchase using innovative and thoroughly tested quantitative-analysis-based strategies.
Available now for an undisclosed number of Credits, with a maximum of some percentage of unexpired Jam Points applicable to the purchase, or included in one of the Bundles depending on your current Gear list or whether you've recently participated in a Group Buy during a Summer Strummer Sale, with the caveat that everything is subject to change and therefore an Upgrade to the books will occur to reflect any new rules, with upgrade prices subject to the rules outlined above. Seriously, there is some confusion about the AT4 "upgrade," which isn't really an upgrade at all, but a new product containing five new Marshall-based amps, new cabinet modeling and mic/room options, and some new effects and other features. If you don't already own AT3, you apparently do NOT receive all the gear included in that product with the purchase of AT4. If you DO have AT3, AT4 does not supersede it but installs alongside it. Any Custom Shop-purchased gear you already own, like the branded amps (Fender, Orange, ENGL, Mesa, etc.), will work in AT4. Still unclear on whether the generic AT3 amps (like the unbranded Vox or Roland models) will work in AT4, or if you need to run those in AT3.
As with all things IK, it's not as simple as it first appears, so make sure you know what you're getting before plunking down your cash (or credits, or ...).
Cheers,
