There are two types of guitar players-those who play acoustic and those who play electric. The two have long been suspicious of eachother, acoustic players resenting the greater volume and spectacular leads of the electric, and the electric (though they won't admit it) finding themselves just a little jealous of an acoustic's earthy, natural tone. But can the two be played together successfully?
I am recently in a band with a couple good friends of mine, one of which plays an electric guitar. I too play electric, but I am known to dabble heavily in acoustic. We have found that it can be frustrating trying to play with the two different sounds simultaneously, but by playing together a lot, we have reached an unsteady compromise - When we play rock, I go with the electric, when we play softer, more slow-paced songs I use the acoustic. It is a wonderful sound when the two genres meet, the warm, resonant sound of an acoustic really matches up well with a softly distorted electric playing over it, as a few bands have discovered. The acoustic acts as a good base for the leads to build on.
Obviously, I'm not saying to try and use a combination for everything, especially rock/metal songs. There is a certain point, though, where the two meet and it sounds great. I'm just throwin this out there, I realize there are many who disagree and thats fine, you do your thing, I'll do mine.
