The four string came out of the case this morning for the first time since February when I bought the five. (I'm going up to the midlands bass bash so I thought I had better check it was still working)
Things I noted in ascending order of importance:
The 4 is much lighter than the 5; the Rotosounds, which I didn't like when I put them on at Christmas, I now really like the sound of and might put them on the 5 when I next change those strings; I need to check the action on the 5, as I've been clanking the frets recently, but I didn't at all on the 4. And finally - I have no idea how to play any open strings any more, so if you want something in a key lower than G then I'm stuffed! ๐
