The lazer was designed by Mark Erlewine, and first patented in 1987. It is a headless design with a cut-down body. At a total length of 31 inches, and weight of 5.5 pounds, it would make a good travel guitar. Scale length is 25.5 inches, 24 frets, with neck-though construction. Pickups are a single-coil at the neck and humbucker at the bridge. These are controlled by a volume pot, pickup selector and push-pull tone pot.

The Blackbird Rider is a compact, carbon fibre acoustic, which Blackbird claim sounds as good as a traditional, full-sized acoustic. Dimensions are 36" x 10.5" x 4.25" (scale length is a respectible 24.5" with 18 frets) and weight is 3 lbs. The recommended retail price (early 2008) is $1600, with an under-saddle pickup as a $140 optional extra.

This is a striking 2 string fretless bass from Atlansia. It would make a good travel instrument as it folds to only 8cm wide by 6.5cm thick (although it is 101 cm long). The body and neck are a single piece of maple, with a folding maple strap supporter.

The hardware is innovative, as you would expect with an instrument from N. Hayashi. The string nut is a Hayashi patented adjustable type, the bass has combined tailpiece+tuners (see photo) desigined by Wilkson and Hayashi. The pickups are ATLANSIA ARSX2, individual click and turn pickups that go in like a lightbulb.
