A month late, but I'll answer anyway. Was a bit disappointed when i tired my bass guitar. Despite all the fancy outside and no signs of use, it sounded crap as fk. Earlier at the week before i even had the guitar, i already bought some strings cause i knew the factory 4-5 year old strings wouldnt be a good idea to keep on. So, first i tried it with the stock strings, and almost all of them were buzzing to the frets and neck. First I thought I'd give it to someone who knows what he's doing but, well I kept on reading the interwebz and found some adjustment tips. So I started on with the neck setup, then string height, intonation, pickup height and lastly I changed the strings to the new, and checked if the setups are still fine. Now it sounds cool I think :P As good as new, if not better.
Just sold mine actually, i'm sure i'll regret doing so one day... i had all the classics too... GoldenEye, Mario, MarioKart, Waverace, Top Gear Rally, 1080 Snowboarding, etc.
I loved wave race as well, played it again about a year ago and it's still fun! However, my recent music gear aquisitions went a little out of hand, so i had to sell some other stuff to make it through the month!
