Gets the job done

This is an easy, fast build, and it gets the job done in terms of what you're buying it for. That said, it's not amazing in terms of user experience.

There's pretty much no way to insert the card into your rack without having at least two modules removed, and the actual surface area of the card is quite small, so you pretty much have to line it up perfectly, probably with both hands, your only options for pushing it in are the small amount of card edge that's exposed, or the soldered connector. Not a great design to require the user to apply stress to soldered components. It would be much better if there was some kind of extension to the card that allowed it to be easily installed from the front of the rack, like a handle that's attached to both ends of the card. Additionally, we're told to orient the card so specific lettering faces down--why not just print an arrow on the PCB?

The extender serves its purpose but can't be easily swapped in and out of a rack without unloading modules, so it's kind of a pain unless you want a floppy dongle permanently installed in your rack.

Essential tool

This is a necessity for me when I am trying to dial in sounds. This extender gives me the ability to quickly and easily swap out colour modules (and it works with any 500-series module). I have two and it they are almost always employed on a channel or two.

It's also a great way to build soldering skills.

These are great, buy two

Title says it all except for one additional thing - Easy Build! I only wish I had bought 2. Let me know when they’re back in stock.

Elegant Solution to a Simple Problem

An easy build, I was done within 15 minutes. This is a necessity for anyone with a smaller 500 chassis and builds their own 500 series gear. Cheaper than an external power supply to test your equipment, this adapter allows more room to maneuver and adjust your gear while using chassis power. Includes spots to measure +-16v, 48v, and ground which comes in handy! Highly recommended. Can't wait to calibrate and easily exchange some DOA's!
