My first post yay! Hi all! I've have got two questions. First question: What is the ideal overall string tension for a short-scale 8 string bass? Ive tried a lot of different searches on Google as well as the Talkbass forums without any luck. Ive also tried to grasp/understand the math behind string tension, string gauge, scale length and frequency, so I could calculate myself to the answer. Rambling/reasoning: I know the gauges and the scale length for my bass(Hagstrom HB-8): The manufacturer has listed these gauges as standard for the bass: G2 - .040 G3 - .015 D2 - .055 D3 - .025 A1 - .070 A2 - .040 E1 - .095 E2 - .055 and scale length is 30,75 I found this formula on DAddario sites to calculate tension: But I dont know the Unit Weight for the strings listed on Hagstroms site From looking at different string charts from both DAddario and CircleKstrings I see that different strings with the same gauge can have different UW. :S I found some other relevant info on CircleKStrings site regarding tension: So with this information I could (based on the hypothetical premise that the 8 string has 4 bass strings and 4 guitar strings) calculate: 40*4+18*4 = 232 lb However this is for 34 scale, and as I understand a 30.75" scale would have a lighter tension, so the above estimate seems unreliable. I tried cross referencing the bass standard gauges listed by the manufacturer to this chart, however I didnt really understand this part: My Norwegian brain really hurts now. :S Any info or pointers would be greatly appreciated. Second question: So from what I understand so far, as long as I calculate the correct gauge vs. tension within the limits of overall neck tension and string tension, I could have whatever custom tuning I want right?
