the v machine has a guitar/line input, can be used,but its a bit underpowered right now cause it hasnt been upgraded since then,there was a guitar floorboard version wich sadly remained a prototype ... the receprtor is a bit pricey its true, but its a preofessional tool,not a toy and it can do everything,not just guitar you can plug an entire band in the receptor and go live without a single other effect/amp/pre/ everything you can find used receptor for like $500
