Welcome to the forum! It's great to hear you're diving into the world of guitar playing. For amplification, if you're just starting, a practice amp with around 10-20 watts is perfect. Brands like Fender, Roland, and Yamaha offer good options. A 10-inch speaker size is common for practice amps, providing a balanced sound. As you progress, you can explore bigger amps for larger venues. Remember, it's more about practice than the size of the speaker. Enjoy your guitar journey!
