Help me customize my harmonica sound for my alt rock project !
Hi everyone !
First of all, Im a HUGE beginner, I started playing harmonica ten years ago because I always loved this instrument (my fav one) and blues is one of my favorite genre, but I didn't progress as much ever since. I dont know any musical theory and I struggle a lot to keep practice (+ Im so bad at improvisation, so sad). I dont play any other instrument except a few guitar chords and melody. Im searching for advice and explanations (very detailed if possible !), because other internet resources kinda lost me haha.
So recently with my friend we started a music project. I really want to explore the noisy side of the harmonica, and I dont know where to begin. I have a Hohner marine band in C, but I struggle with the first three holes and Im much more confortable with the 4-5-6 in general (the only ones I can bend). What could you advise me for a very low, very deep sound in term of other harmonica / key ? I like it when it sound rough, deep, low and bendable.
Second question : I would like to make some electric sounds with my harmonica, to play with the harsh noise wall / industrial / noisy / experimental / concrete style of our project. I think I understood that I need to buy a microphone to connect it to my amplifier (a very old guitar amplifier + my cats scratched it a bit haha, dont know where it comes, picture below). Do you have recommandations for microphones and maybe amplifier that could suit my idea ?
If you have any advice, i'll take it with pleasure ! i feel like a HUGE poser but right now we really want to start doing something with my friend so i guess i have to dig it for real. Thx !!
