## User Pros & Cons

* 👍 Pros: Incredible value for money; solid, tour-ready metal construction; lets you bypass traditional heavy amplifiers by going direct to a PA system; capability to load your own custom cab IR files.
* 👎 Cons: Limited physical controls with only two footswitches, which requires "menu diving" or switching between Patch/Stomp modes during live sets; does not feature any MIDI connectivity; certain high-gain or modulation effects can sound noticeably digital compared to boutique alternatives.
