Hi everyone! First of all I would like to say that my native language is not english, so I will try to explain myself as good as I can This is my first thread in which I would like to ask a question a friend of mine asked to me, hoping he could get some answer from me, but I couldnt give him a good result, so that is why I'm looking for others help So, my friend is building a homemade bass guitar, and he often asks me questions about electric components to make his instrument sound better, and a few days ago he came with some ideas from an article he read about piezoelectric components, and wanted to know if he could make his instrument sound with this kind of component. I talked him about the normal use of this materials such as ceramics, which are used in instruments with a resonance box. Ej: upright bass But he had the idea to make an about 10x2 cm rectangular piece of quartz to use it as a pickup, (a pickup in a bass looks like this http://citron-guitars.com/cms/wp-content/uploads/2011/10/pickup_bassJ4.jpg and is a simple use of magnets that are affected by the vibration of the metal strings of the instruments ) After a little research in the internet I found out some stuff about this piezoelectricty concept, but anyway I dont know if this is possible and neither I know what to answer him So: Would it be possible to make a string instrument(in this case the bass guitar) sound out of the catchment of the vibration that the strings make in the air with a "piece" of quartz/ceramic? I've posted this thread in earth threads space because I dont know where to post it exactly Hope you can help me out! Thank you in advance!
