I know to play guitar and I can't play Harmonium. I like harmonium sound very much. So, if it is possible to make Harmonium sound from guitar, then we have infinite possibility to compose music. So I am thinking the possibility of making Harmonium sound from guitar. Is it possible ? if so, how can we do it ?
There is a special pedalboard made by Boss, that will help make any sound you like using a guitar. Unfortunately, it needs an electric guitar, and a special pickup, usually fixed properly into the guitar. All at a fair cost!
You're not going to get what you want cheaply or effectively without that sort of thing - or getting a guitar to produce a MIDI signal, and then you'll need a sound processor to plug into - and an amp to be able to hear it.
