I am looking for a resonator guitar that is all metal body and has the classic F hole look. What comapny originally made the first ones that Delta Blues slide guitarists used way back when? I am looking to spend around $1000 maximum and want to know what comapny will make one of these that sounds best and is the best quality for around $1000? I have taken note of 4 comapnies making these: Epiphone Regal Johnson Dobro If any of you are experts in this area, please inform me. I am new to resonator guitars but love the sound. Thanks for your help folks!
