Intended to work with guitars, basses, and keyboards, the Tonebone Mix-Blender from Radial Engineering is a stompbox that lets you mix two effected or unaffected instruments together and their combined signal through a dedicated, mixer-style output. It offers two Class-A buffers to ensure signal fidelity and is useful in many applications, such as blending two acoustic guitar pickups, combining two separate effects in parallel, or facilitating quick onstage change-overs between two different instruments set to the same output level.
Furthermore, the unit boasts its own effects loop, which can blend additional insert-effects to taste. You can instantiate this loop via the on-board foot-switch, and use this feature to add a touch of distortion in parallel to your dry signal, a smattering of chorus to your otherwise unaffected tone, or indeed, in a great variety of different ways.
