I'm sure the two pieces must compliment each other. I'm no violinist (I play guitar) but I imagine having a top of the line violin would be no good if your bow is cheap junk.
It is the same to a guitarist as the amplifier he uses.
Watch out! There are some guitarists who would tell you that electric guitars and amplifiers are an abomination. Some purists don't even like the accoustical guitars that are amplified. And don't even start a conversation about which brand/guage of strings are the best, LOL!
