Eden Metromix Series Multi-purpose Amplifiers USM-EM25-U 25-Watt Guitar Amplifier Head

I have had this amplifier for about a month now, and can't recommend it. I bought it because I got what I thought was a good price on it and liked the features, but sadly, it was a total waste of my money. It sounds barely adequate with a Les Paul, but thin and cheap with my Lace Sensor equipped Strat. You can add pedals, but they don't help much.I also don't consider it multi-purpose. It is useless for bass guitar unless you want to use it as a back rest while you play, because at more than a low speaking volume, it can't manage bass. Won't even keep up with my lowest power 1/2 watt guitar amp through a 10" speaker.The real bummer, is that it is wretched with headphones. I have tried multiple headphones, in both jacks to make sure it wasn't just a bad jack, and the hum is always so bad that you're better off just playing your electric guitar unplugged. The hum is lowest with the gain at about 1/5 and the headphone volume at about 1/3, but it's still not acceptable. It also doesn't change with the guitar volume, touching the strings, or even unplugging the guitar, so I know it is just part of the amplifier. In fact, if you put the headphone volume down to 0, it goes up, so maybe they just did a horrid job with ground loops.There are a ton of great amplifiers available for less than this one ($199 delivered as I write this), so I would highly recommend avoiding this one model. I had thought a little transistor amp would be safe, but after this purchase, I'll never buy an amp without hearing it again.

This is a great little amp with all the hard to find features we were looking for, 2 inputs so both guitars can be played together, an MP input so one or both guitars can play along in real time. It's a very good learning, teaching amp and has enough adjustments that separately control each instrument for a wide array of sound. It does not have built in distortion so I only gave it 4 stars. If you want distortion you'll have to get a separate fuzz box. With 2 headphone jacks the players can be in their own world without disrupting the whole house. It's plenty loud and the price point was reasonable.

I found this amp to be very useful for bass guitar keyboards and drums as well as acoustic also I use it in a large room and it did fine. leading me to beleive a previous reviewer has a bad amp. My uses range from performace to home studio aplications and get real silent sound very happy with mine.
