Wired Adapters
Some instruments require special adapters to connect to your computer. For example, non-USB PS2 guitars will require a PS2-to-USB adapter. Alternatively, you may choose to use a wired adapter with your Wii guitar to eliminate the need for a Wiimote and Bluetooth.
It is possible to craft your own wired adapter for both PS2 and Wii guitars. See this website for a comprehensive guide of everything Arduino-related.
Note that Etsy listings may change and new sellers may come to the market. We recommend checking the seller pages in case new adapter revisions have been released since this page was last updated, as well as searching Etsy in general, in case better deals are available.
Wii
Wii guitars will work with a wiimote and bluetooth using the Wiitarthing software, however if you do not have a wiimote, an alternative is to use a wired adapter. Keep in mind that tilt on Wii guitars is handled by the wiimote, so for tilt to work with an adapter it needs to have it's own tilt sensor on board. You can create your own following Sanjay's guide, or you can buy one from the following sellers.

Raphnet Classic Controller to USB Adapter
Does not have a tilt sensor. This used to be the standard recommendation, however various sellers on Etsy have begun to offer equivalent or better products at lower prices. However, this may be your best option if you are outside of the US.
EMiO Edge Gamepad for SNES Mini - Super NES
No tilt sensor, whammy and analog stick don't work, does not support drums. The bundle comes with a gamepad and adapter, but the adapter is all you want. You will likely need a USB extension cable since the adapter cable is extremely short.
PS2
PS2 adapters let you use guitars with Playstation 2 controller connectors on them, like the SG. There's many cheap options available, and a few higher quality options.
You can also craft your own PS2 adapter by following Sanjay's guide or buy one already built off Etsy. Note that Etsy listings may change and new sellers may come to the market, be sure to search there for the best deals!
Etsy: Blue Indigo Adapter
Sold by HSMods. Supports Whammy on both Mac and Windows, tilt is only supported on Windows. Contact Discord user @hondysondy in the Clone Hero Discord for direct support.
Raphnet PSX Adapter
Known to have 100% compatibility across all operating systems. Whammy works just fine. Best option, though also the most expensive one and often out of stock. May not be available outside of the US.
The following PS2 adapters can be often unpredictable and of poor quality, although their cheap price can make them worth it. While we try to make recommendations of ones we believe will work, we cannot make any guarantees. If you are going to use one, please be aware that not all adapters offer whammy functionality.
If your adapter does not work at all or has incorrect bindings, please see the PS2 Adapter Fix in troubleshooting for a possible solution.
