I've had a Elf for a year or two now, primarily as an emergency back up- plugging in at a gig just to check it's working, then back in my leads bag, and cracking on with my main amp.
At a rehearsal last night, I took it along rather than my combo, and used it with a 112 cab. Sound was good for about 2 minutes, then a mass of distortion. Kept having to turn on and off, to give me a sound through a song, then the same- all night.
Just had it out now, and tried various cabs, speaker leads, guitar leads, and different basses, and it's the same.
I presume these little class D amps are basically a write off if they go wrong? - ie too expensive to fix, compared to just buying another one?
