Yeah, this is definitely a good place to ask in regards to tone and what that will mean for you considering everybody plays similar instruments, but unfortunately any reliability issues that crop up here will be statistically insignificant.
hey Guys,
There are protection circuits in all our amplifiers that shut down the amp when the power is too high, the amp is too hot, or the impedance load is too low. This protects the amp from blowing up, essentially. Better that it shut down than fry!
And the shut down is temporary, if you try again when the power/impedance temperature are acceptable, the amp should be fine.
It's hard for me to say much more than that as a general statement, there's always so many different variables that it's dangerous to make too many general statements without knowing all the variables... even then, I'm not an engineer myself.
Our amps operate at a 4 ohm minimum, and it's true that some cabinets are not accurately identified as far as impedance goes. So if you plug into a couple of 8 ohm cabs that are actually 7 ohms each, you're at 3.5 ohms, which is below 4.
We have experienced very few problems, so it seems to be a rare issue, but I think this has happened. If it does happen, your amp isn't broken, it's just protecting itself! And be glad that it is!
I've seen the list of defective amps returned to GC, and honestly, it's a handful compared to the amount sold. Our reliability rate is currently around 0.6%, which means that 6 in 1000 experience some kind of problem. Those are pretty good odds.
Cheers,
Peter
