Caline Scuru 5W Portable Rechargeable Caline S1G Mini Electric Guitar Amplifier PERSONAL NOTE* I use one of these to test pedals etc and i have found they are very loud (maybe 10W ) tone from clean to intense metal distortion, it has a full tone just enough bass and enough highs, with it's long lasting rechargeable lithium internal battery, makes it perfect for basking, beaches, small parties, and of course with optional headphones a perfect amp to practice in private, has aux input for listening to tunes while practicing. I give this amp 3 thumbs up. LOL OK 2 thumbs UP !
