Hi all,

I searched around in this forum and found very interesting topics about the Peavey Standard 260H, but no clue about my problem. I just got a 260 head. Normal channel sounds perfect, exactly what i was looking for. Effect channel seems killer, but I meet some problems:

There is no sound coming out until I crank up the gain knob almost to the max. But it doesn't seem that the knob is defective: no noise while turning the pot.

It depends on the input signal. If I play soft notes, no sound. If I play a loud notes, there is sound. But as the note progressively dies, the sound will cut off brusquely, like a noise gate.

I made a video to show so you guys can figure it out:

Also, we can see in this video that the distortion knob (bottom left) has no effect on the sound. Another weirdness...

One last thing. I got it from the US and I'm using a voltage converter from 220 to 110V. The box is supposed to handle 300W, but the amp use 400W. Although I understand I should get a more powerful converter, I don't think this explains the problem on the Effect channel.

Thanks for your help.
