Still use mine every week at gigging volume levels for band practice, and have done throughout lockdown.
Still think it sounds amazing. Absolutely superb bit of kit at any price. At the price they sell it it's ridiculously good.
Never had a single problem with it, and have no intentions of replacing or"upgrading" it.
In fact, if and when I've got a bit of spare cash floating around I intend to also buy the valve version.
