not true - my rig cut out after repair, with the 8 ohm pf 210
Which is why I said "in my experience", and not definitively "yes" or "no".
Now I can't help but wonder if my PF500 will cut out with my PF115HE.

not true - my rig cut out after repair, with the 8 ohm pf 210
And mine has never cut out powering 2 410 cabs @ 4ohms.
People seldom report lack of problems, because that is the expectation. The problems are readily discussed to the point where the overwhelming majority of posts discussing these heads are about failures of one sort or another.
I'm not saying these failures didn't happen or were a result of operator error, just giving a context for what you will find if you look for feedback on these heads.

I play a MIM Fender P with Duncan Quarter Pounders and I have yet to make the peak light on my PF500 blink. Not even once. A friend let me play his '86 Westone Spectrum through it and I didn't even think about changing any of my settings before plugging in. Immediately the peak light was flashing like a cop car. I dialed back the gain and got it to quit, only lighting up occasionally when I would really play hard. I wonder if the 'cutting out issue' might be related to signal strength from your bass to the head and less likely related to cabinet/s used, resistance load or 'pushing the amp too hard' ? Is it possible that this amp just doesn't tolerate super-hot signals or active electronics well ? Like maybe, regardless of your settings, if you've got a hot bass it may not play well with this amp ? Thoughts ?
Are you saying that even with the gain turned up all the way and with the db pad switch out or off, your peak light doesn't come on at all? In my experience you should at least get something out of the peak light with the gain turned up all the way.
Possibly you might not see the light if you set your action high and the pickups are set low and farther away from the strings. When I was using quarter pounders, I found them to be a little bit hotter than the stock pickups. I was using 500K pots on mine versus the stock 250K but I really don't think that would make much of a difference.
I see the SVT Pro7 has been mentioned here, I do wish folks would not post like that as I feel some GAS developing whereas the PF500 and BF cab had remedied the previous build up![]()

This is exactly one of the things I was saying a few pages back. My basses are all passive, and no problems even with 4 ohm cabs. But when I ran them thru the MB SuperSynth with a very hot, spiky synth setting, I had no trouble getting this amp to clip. But it took a hot signal and 4 ohm cabs to do it.
Just for the sake of counterpoint and adding positive reports in where possible, I run all kinds of crap through mine and still haven't gotten it to cutout. Granted this video the volume is lower since I was alone in the space, but running this at full volume also isn't an issue.
Any one of you more Ampeg familiar types want to give me an idea of the similarities or major differences between the PF500 and the SVT 7Pro.
