I have been friends with everyone in my band for a long time, we all love playing the same music and get along well, but our only problem is the only other person we know who would fit in as a lead guitarist for the band lives in Arizona for now ( we are in California ). We have tried other guitarists but they were either not good enough or didnt like the genre's we played ( death metal, thrash metal ). Due to the lack of a lead guitarist a lot of our parts sound very small and empty unless i am harmonizing with the rhythm, which is fun at times, but unless i am playing the same thing as the guitarist the riffs sound too hollow. I have experemented with different EQ's and multiple lines and different fills ( im not that good of a bassist but i experiement as much as i can, seeing as how we play these songs dozens of times per practice ) but it just doesnt sound right. now, getting a small bass break here and there and harmonizing in octaves, fifths, or thirds with the guitarist sounds cool at times, but it gets boring for me. any of you know of any solutions?
