Another difference is the number of speakers. The 60W amplifier typically has a single 12-inch speaker, while the 2X30W amplifier may have two 10-inch speakers or four 8-inch speakers. The larger speaker in the 60W amplifier will produce a louder and fuller sound than the smaller speakers in the 2X30W amplifier.
Finally, the 60W amplifier may have more features than the 2X30W amplifier. These features may include a reverb unit, a tremolo unit, and a distortion unit. These features can be used to add different effects to the sound of the guitar.
Overall, the 60W guitar amplifier is a more powerful and versatile amplifier than the 2X30W guitar amplifier. However, the 2X30W amplifier may be a better choice for someone who is looking for a more portable and affordable amplifier.
