ID Core Beam : Great product!

Good for what it was built for. Fast connection with mobile phone. Good sound quality. Very portable. Volume quite loud actually. Played bass several times, quite OK. Played electric guitar. No so good because I use valve tube amps (from Blackstar...),but OK for a solid state amp. Tried an acoustic guitar once, and it was OK too. The effects are a plus. For practice, for small parties, to sing along with friends, perfect. As a music workstation at your bedroom with this possibility to had your bass, acoustic or electric guitar, there is no match for this. Of course that quality is questionable when compared with dedicated products, but all of that combined and you're looking into more space and other budget!. Will not put mine aside.
