ideas

Well I have been expanding my rack and loving every minute of it, but could use some suggestions. First thing is I have a Pittsburgh 420 that turns out is actually 423 HP. The bottom row is actually a tiptop happy endings that I have mounted in my studio desk and is completely full, but the top row has 23 HP available.

I am looking for interesting modules to fill out this case.

Let me know what you would add and what makes it an essential component of your kit (I have considered PNW but I have a lot of that covered and not sure I am in love with the menu system for the types of functions it provides)

Because you have an odd number of hp left, might I recommend the 9hp Patching Panda Punch v3? It’s a super useful and surprisingly inexpensive dual VCA/envelope generator and more. It looked kind of cool so I picked one up and now use it in everything. Definitely worth looking into.

One other "odd number" solution that I like to include on builds: https://www.modulargrid.net/e/konstant-lab-pwr-checker-wh

1 hp...and I have to concur with KonstantLabs here - this IS the most useful 1 hp device ever, period, especially if your cab has no visible DC rail indicators.
