Hello, i've got a 6 strings bass but i don't want the low B, I prefer to have high E, just like a guitar : E. B. G. D. A. D. I'm looking for a solution to have the same sound with all of them. Thanks and sorry for my poor english.
You're going back to the 1962 Fender Bass VI - which was also known as the "baritone guitar"! G&L also produced one in 1991, but I don't think it was very popular and never got past the prototype stage! Basically the question that is going to be asked is "Well why not just play guitar with an octave pedal then! " Also - "why are you posting in the Double Bass forum? "
Your english is fine. I understand your question perfectly. As for your string question, I really wish that I had an idea for you. Have you tried contacting any of the string manufacturers? You might try posting this question on the BG (Bass guitar) side of TalkBass as well. You might have a better chance at getting it answered. Brought to you, without needless sarcasm...
