Making the decision to learn electric guitar is a source of excitement. An entire world or sonic colour, passion and musical bliss opens its doors! Often its some kind of inspiration such a great rock solo you've heard or simply life telling you go here, that makes you want to take it up.
Since acoustic guitar is often the cheaper option to start with most people begin there and move on to electric after a year or so. It certainly doesn't have to be that way but having some playing experience on acoustic guitar - strumming chords ECT, will help you to progress that bit faster on electric.
An important point is to think about which direction you wish to travel musically. Learning electric guitar for Jazz is vastly different from Indie, or Blues from Metal you get the idea. Once you know what it is you'd like to be able to play it will simplify the search to find the right electric guitar lessons for the direction you wish to travel.
