I just started playing around with a Fender Frontman 10 W amplifier and I find it hard to use consistently.
First, the biggest annoyance is the constant hum and static. I've read that the static occurs from environmental interference and "ground loops"... So perhaps this is unavoidable.
My second concern is that the amplifier just arbitrarily drops nearly all sound. All I did was turn the treble up and then back down or the volume up and the amp doesn't seem to be producing any sound anymore. A quick fix is found by shutting off the amp and turning it back on. The sound is often different between me turning off and on the amp with the same exact settings.
So my question comes down to - is this just what is expected from an entry level practice amplifier that comes bundled with a starter electric guitar pack?
Would I be better off separately purchasing, perhaps an even cheaper guitar such as a Squier Bullet Stratocaster, and a slightly better amplifier such as the Marshall MG15CF or the Fender 20 W Champion?
I ended up returning the amplifier and getting a Fender 20 W Champion amplifier. After hearing the difference, I'm convinced that the amp, as suggested below, was faulty! The new amplifier is near silent and works really well. So ultimately, a new amp should not hum :)
