The battery does make a difference in its overall performance, but we have what we have.

It must be pointed out that the Yamaha THR is a good choice for relatively small gatherings only. This is because it is not loud enough to be played at big events. So, if you are to perform in an auditorium, you may need to look at some other guitar amp.

With 2.8 kgs, the Yamaha THR is pretty portable, and carrying it around would not be a problem for you even if you have a bad back. For better portability, it comes with a handle at the top.

Design-wise, the Yamaha THR is as good as anything. It is mainly constructed of plastic, and the metal finish adds to its elegance and durability. It has three emulated circuits, i.e., classic, modern, and boutique circuits.

If you are low on the budget, the high price of the Yamaha THR might be a deal-breaker. On the other hand, the Positive Power Grid is relatively inexpensive, and you can easily afford it even if you have a tight budget.
