HI all, im just wondering if anyone cud help me with some problems ive got. I got a few questions, so ill list them. I want to downtune my bass (5 string) to B F# B E G# Q1. i know i have the top B on my low B string, but will downtuning the other 4 strings so much damage the neck, like warp it? i heard that if you leave a bass where some of the strings are tuned more tightly or slacker than the other strngs the neck can get damaged. In other words, is it fine to leave my B string as it is and downtune the other 4 strings? Q2. ive got heavy gauge strings, "Power 5"s from ernie ball i think, so will these be enough or could i just get medium and sound ok? im only asking this because my B string sounds very dead while the others very responsive and snappy, which is wierd and i wanna get rid of them for a more comfortable and perhaps better sounding medium gauge set. Any recommendations? Q3. my bass is the Aria JBDX5, a five string superjazz style bass with single coil jazz pickups. should i have gotten something with humbuckers? or will the single coils give me better clarity at such low tunings? i think my neck is the longer style one too, the 25 inch that is good for b string clarity. Q4. Are all the strings dowtuned so much to the above tuning or can you tune some strings up? is this bad for the neck? for example, my E id tune up to F#, my A id tune down to B, my D id tune down to B, and my G id tune down to E. Then again if i did this would there be unequal pressure from the strings and therefore my neck or bass would get damaged or is this the way i should do it? Q5. My tone/volume pots make a scratchy sound when i move them, what should i spray down em to stop it? is it dust or rust or something else? Many Thanks for all your help guys, these are questions that have bugged me for ages now! sorry ive asked so much!
