In the words of EarthQuaker Devices:

Pedalboard Reconciler Swiss Things combines two true-bypass Flexi-Switch enabled effects loops, a Flexi-Switch AB-Y box with transformer isolation between outputs, a buffered tuner output, 20dB of clean boost with adjustable gain, an expression pedal output for volume control and a quiet, high headroom output buffer into a compact pedalboard-friendly signal routing junction box that lives at the top-right corner of your pedalboard and
really ties your rig together without any signal loss.

This is what you can do with it:

• Use as many pedals as youd like without tone-suck
• Quickly and easily bypass or engage all of your effects with one click
• Use Flexi-Switch Technology with every pedal in your setup
• Eliminate volume pedal tone-suck by using any expression pedal to control volume
• Use multiple amps without phase issues, ground loops, or extra noise
• Tidy up your rig, shorten cable runs, and reduce tone loss by keeping all inputs and outputs in one location
