Before I bought this amp I red many comments about him and also I watched and listened to on youtube few videos. This small amp looked very promissing, so I decidend to try it. I bought it in a bundel with Joyo B110 Bass Cabinet 4 Ohms and I need to say that this is really powerfull equipment. I'm very surprise of the sound how selective and deep it can be. I love very warm sound and here I can achieve it. I have standard and freetless base guitars, so the second one sounds really amazing. In my collection I have two more bigger amps (combo 250W, and amp with two cabinets 2x400W) but right now, Joyo is my favourite one :) I love it. Small cabinet sounds really great. I'm also using bluetooth and this is what I wanted to have. I can play a drum background from mobile phone or laptop, this is very easy to use.
The on thing is very hard to say for me. I have never played with this amp and cabinet with drums, so I can't say if this will be enough for the band practise? It is really powerfull, so I think that this 50W of amp and 100W of cabinet should be enough to play with drum and guitars, but I'm not sure this.
I can really recommend this product. It is small and it plays beautiful sound.
