There are a few drawbacks to consider. The plastic construction, while lightweight, might not feel as robust as other metal models, leading to concerns about durability over time.

For those with specific needs for extensive tonal shaping or who require heavy-duty construction, exploring other options may be advisable.

The weight of 12 pounds makes it somewhat bulky and less portable, which might be a concern for gigging musicians. While the product is well-built and reliable, some might find the price point a bit high compared to simpler attenuator options that could suit casual players. The USB connector is a nice addition for recording purposes, but it may not be essential for everyone, depending on their setup.
