The Multiswitch does unleash your Timeline's full potential. The looper functionalities it unlocks (reverse, half speed) are great, but all the other modes are handy to have. Fits well with the main unit, beautifully crafted. Switches feel and work great.
Reserve space for the jacks of the TRS on your board. You can't line the switch up with your pedal edge to edge without turning the switch around 180. Would be also great to have Strymon consider including LEDs to go with the switches as it sometimes can be difficult to know whether you successfully started recording a loop or an overdub without feedback like that. There is a reason why the default looper mode gives you those cues. Another thing to improve would be the size of the TRS cable included with the unit, especially the jack. It takes perhaps a little too much space. At the same time, it's good that it's not running directly into the unit, and therefore one can swap to a cable with less space requirements.
