Relish come from near where I live. They are really nice guitars. The Jane model is their super high end, but they make a similar design aluminum framed model for around 2500 bucks. They even have a solid wood framed model that is under 2K over here (I see them at around 1800 bucks in shops).
The company is run by two brothers who won a bunch of design and business awards here. They idea was to redesign the guitar with more modern materials and practicality.
The fretboards are made of bamboo, rather than rosewood. as it is harder, apparently good sounding, and more sustainable. The front and back wooden body panels are free floating wood veneers, and the aluminum frame with those veneers mimics the sound of a hollow body type guitar, but without feedback issues. These things are super resonant like a hollow body, but thin like an Ibanez S series, and they sound like a real acoustic through the built in piezo system. The conventional selector pickup switch is a touch control that allows you to have it work like a regular push button switch to get front, both or bridge pickups, or like a slider that can deliver any range combination by touch that you might want (so you can get 93 percent neck, 7 percent bridge, if you want that). It also allows for blending of the piezo signal with the humbuckers. The pickups basically pop in and are held in place by the frame, so you can swap them out in maybe 2 minutes. Remove the magnetically held on body panel pop out the pickup, pop in another, attach the quick connect wires and go. The shape looks weird but the guitars are incredibly comfortable to play, as Swiss people are somewhat obsessed with ergonomics of a design. Playing these things feels super cool as there is not a single part of the guitar that doesn't "fit" you when playing.
The one I played had the nicest fretwork I've ever played and the fit and finish are amazing on these. I'm going to pick up a Mary model one of these days. The output of the shop is not high, so they make these in small batches, and I'm waiting for some wood top (maybe black walnut) Mary models to come back into production.
