Not the cheapest but very likely the smartest choice if you are looking for a versatile, easy to handle, pocket-sized portable amp to serve your practicing needs.
This quality made device gives you full freedom to play and enjoy a plethora of rich sounds wherever and whenever you may wish to do so, as it only requires a charged battery (which will serve you at least for 4 hours) and a set of (wired) headphones. (BTW, I’ve been frequently using a standard set that comes with almost every smartphone and even so the results are more than satisfactory.) Should you wish to play along a backing track, the Bluetooth feature is readily available with a switch of a button.
I realize that the above might sound more like a manufacturer’s ad than one’s personal opinion based on experience, but I was really impressed and got more than I had expected with this little fellow. Well, OK, I do miss the possibility to connect wirelessly to a set of headphones, but … you can't allways have it all, can you :)
Unfortunately, most probably because of the current pandemic and its various consequences, delivery time is painfully long but the gadget is well worth waiting for.
