Hi Juanma, welcome to the Handmade Music Clubhouse - Cigar Box Guitar Headquarters (CBG HQ)!
The focus here is on all types of handmade instruments and music. There are lots of helpful builders and players here and lots of Groups to teach and learn. We welcome participation so don't be shy.
Have a look around, introduce yourself in My Name Is... and add yourself to the Member Map. There's an active Chat Room where you can ask questions, offer help or just talk about anything with some great folks.
