Ah, clearly I was being a numpty this morning.

I was trying to tune my Charvel Surfcaster bass, which had a medium guage standard set on it, to G D A E to work out how to play Red Hot Chilli Pepper's song By The Way. The E and A made it up G and D but the D staring bust at G#. I didn't try the 4 and a half steps increase needed to move the G string to an E. Could someone enlighten me on how I get this tuning right. Do I need to buy individual strings and if so what size for each? Or should I be tuning some strings down instead of up? Marc
