Yep, you can mount a power supply underneath the Pedaltrain Classic Jr SC. Based on what we found, folks like this feature since it helps keep everything tidy and leaves more space up top for your pedals.
The Pedaltrain Classic Jr SC is pretty popular for being both sturdy and lightweight, making it a dependable pick for plenty of musicians. It has enough room to fit a bunch of pedals and comes with enough hook-and-loop tape to keep them in place nicely. From our research, this tape usually does the job, but if you're planning on moving it around a lot, some suggest going for something stronger like 3M Dual Lock to keep things really secure.
On the flip side, you might want to think about the quality of the soft case that comes with it. We've found mixed opinions on its durability and how much protection it actually offers. The pedals sit right against the case's padding, which some feel is a bit thin—something to be aware of if the case takes any hits. Plus, there's the issue of no extra pockets for cables or accessories.
If you're moving your pedalboard regularly, it could be worth upgrading to a more padded case or adding some extra cushioning to the existing one for better protection. Even though the Classic Jr itself is well-built and functional, protecting your gear, especially if it's pricey, is always a good idea.
All in all, the Pedaltrain Classic Jr SC is a reliable choice with the handy option of mounting your power supply out of the way.
Whether you stick with the included case or get something tougher, it's a solid piece of gear for managing your pedals.
