I use the Cab Merger to connect two Marshall 10" speaker cabinets to amps like Bugera G5 Infinium and Hotone Nano Legacy amps.
This little device lets you connect one or two speaker cabinets to any amp with only one speaker output. You can choose to connect the speakers in series or in parallel, so the impedance can easily be matched to your amp.
The device is made of metal and the construction feels very sturdy. I wouldn't worry about stepping on this.
This is easy to operate, and all the instructions needed are printed on top of the device, so no instructions flyer to misplace.
