1. Sunn Amps in general for both guitar and bass.
-2000S model amp and cab, updated with all the back panel trimmings of modern amps and maybe a blendable overdrive channel, and neo speakers (such as the Faital 15PR400 for the cab).
-Maybe a Coliseum or Concert Bass type SS preamp with a Class D power section.
-Also a 200S/2000S type preamp with a Class D power amp.
2. Guild B-300 and B-400 series basses.
3. Gibson basses.
-Thunderbird II and IV with the old school style pickups with chrome covers.
-EB-3L with real mudbucker pickup and slotted headstock.
-RD series bass.
-Triumph bass.
-Victory bass.
-Explorer bass.
-EB-2 (the hollowbody one)
-EB-1
-Also all basses should be offered in all finishes.
4. A few Rickenbacker basses.
-4003S-8 8-string bass.
-4080 but with the option to make the bass neck 8-string as well
-A modernized 4002 with selectable active/passive electronics and 24 frets (would actually work on a 4002 due to having very different pickup positions from the 4003).
-Model 2000 series basses.
-Model 4005 (I know, total pipe dream).
-Produce a model based on their 1930s EUB prototype.
5. Ampeg B-25 but modernized. I know, the PF-50T is nearly the same thing, but it would still be cool.
Also a 2x15 from Ampeg would be great.
6. The Sound City amps with the active EQ sections.
7. Fender stuff.
-Big Block P-bass with the big fat humbucker.
-The Katana bass. I know, silly, but cool.
8. MusicMan should issue a model like the Stingray prototype - with the Reverse P-bass style pickup where the big humbucker normally is.
9. JBL should make instrument drivers again. Something similar sounding to the K-140 but with modern power handling an excursion.
10. EV should do the same with the 15B.
