So my buddy calls me the other night all excited and wants me to come over and check his new Amp out ! I get there and see it's an Ampeg and instantly I'm not impressed . I've never been an Ampeg fan , just feel like Ampeg has a sound all it's own and I don't like it . Their gear will last a lifetime and it's very well designed just not for me . This amp is a a b1-RE and is rated at 175w at 8 ohms and 300w at 4 ohms . Controls are minimal and solid as a rock . Plugged it into a 4 ohm cab and let it rip . I was very impressed with this little amp , first for seeming more powerful than it is . Sounds more like a. 500w amp . Handled everything I threw at it with ease and for a solid state amp was very warm probably the warmest solid state amp I've played . I'm actually building my own small portable rig right now so I ordered myself one . So if your looking for a small , cheap , powerful , easy to use rack mount amp you need to test drive this one for sure .
