There are a number of "wish list" type threads within the forum. I think think the most recently active has been the "Do we have an Amplitube wish list?" thread that started sometime in 2015 and (at the time of writing) was most recently added to in June 2018.
But you can never have too many!
Here's a brief version of my current gear model wishlist:
- based on Marshall #1959 100-watt Super Lead (with appropriate matching cab models, if not already available).
- based on Marshall #1992 100-watt Super Bass (with appropriate matching 4x12 and 4x15 cab and speaker models).
- based on Marshall Master Model 100w Lead #2203 (with appropriate matching cab models; this would basically update the old Vintage Metal Lead model).
- based on Laney 100w Supergroup (with appropriate matching cab models).
- based on Bogner Ubershall (with appropriate matching "based on Uberkab" cab model).
- based on Dallas Rangemaster Treble Booster (perhaps with "switchable" options to approximate modded versions used by different famous players?).
- based on Hornsby Skewes Treble Booster (probably the more common silicon-transistor version).
- based on Colorsound Power Boost.
- based on Binson Echorec 2.
- based on Colorsound Wow-Fuzz (but I would be OK if this were separated into a wah stomp model and a fuzz stomp model).
- based on Boss CH-1 and/or CE-2 and/or CE-5.
Then, besides the "update" for the old Vintage Metal Lead amp model listed above, I would be happy to see some of the older AT2-era stomp models updated or reissued with improvements. For example, I would definitely be into new "based on" Big Muff Pi, Small Stone, Tube Screamer TS-9, and Boss HM-2 and BF-2 stomps -- though, really, virtually all of the older stomp models could do with a refresh. Some of them, like the "based on" Big Muff and/or Tube Screamer updates could usefully include have "switchable" options for emulating slightly different circuits from different versions of the original gear.
