I had other brands before but after buying this, either with my electric guitar or bass, this is the tool I use at nights for silent practices and jamming. It has 4 setups for bass and for guitar. For guitar I am mainly using two of them. One for clean with reverb, one for with some gain and delay. Same for bass, I use one setup slot for clean with some reverb and one with the effects.
When I want to jam, I setup this as a bluetooth speaker to my phone. Find a jam track on youtube and just play. All the sound from phone and guitar comes from headphones. No lag issues.
The charge holds well, I never could be able to deplete it on one go.
The best part is; Now I can bring my guitar to downstairs and jam when I'm watching the puppy or watching some old Star Wars move in the background :)
