I had low expectations. 6 watts with two 3-inch speakers is of course limited. Even going in knowing those limitations, it still managed to disappoint me. Some of the reviews and some of the videos sounded promising. Yet after trying this little amp, I couldn't recommend it to anyone. Not to a beginner. Not to a casual busker. I was looking (hoping) for a small battery powered green room/backstage amp. Something I could throw into my backstage duffel bag and use for warm-up, song run thru, and harmony rehearsal. Right now I either use a GK MB112 (which is a hassle because it's yet another heavy item on an already fully loaded gear cart) or earbuds/iphone interface. Was hoping the Blackstar could split that difference. Maybe I got a defective unit because neither the amplified, nor the headphone, sound is viable. The next option might be to look at the Roland Micro Cube RX. Any other thoughts?
