    A quick search on the big box web site and I find dozens of light class D power amps in the $399-$499 range. Most are 350-500 watts. My question is do we consider most of these gig worthy? There's a small sample of these available locally for me to try out, I think just the Ampeg and Fender at GC. So, should I buy just what's available, that I can try out, or go out on a limb and order something? I'm abit concerned that some of these might not be so rugged. Your experiences would be appreciated.

    Depends on the gig. Particularly with PA support, all the volume you need is just to hear yourself. 350 Watts with any decent cab will knock you down. Generally we use a lot less than that, just too loud otherwise. On the other hand, if no PA support and a big, or especially an outdoor venue, you will need more Watts/volume. Most of the big tube heads come in right around 300 Watts (Ampeg, Fender) and are plenty loud. 350-500 should be fine.
    Confession - I use Genzler Magellan 800 Watt, but only because I bought before the 350 became available. Fine amps.

    Thousands of people have been playing gigs with those amps for 10+ years. Does that answer your question?

    I believe most touring shows have gone Class D with their power amps.

    This is what I use:
    Crest Audio Pro-LITE 3.0 Professional Power Amplifier 3601250

    ...though I’m NOT shilling for that vendor. Just what I found.

    Anyhow, the ProLite 3.0 will pretty much take your head off. You actually have to be careful how you use it. If you need more than that for any live show, I’ll be listening in from the next county over.

    My entire PA runs on class D power. 3 Peavey IPR2 7500’s, and 3 Peavey IPR2 5000’s. These things get used hard, in all sorts of conditions. Never so much as a hiccup.

    My bass rig is class D (currently a Bergantino B|Amp, before that a Genzler MG800). Never had an issue, ever.

    I think I could have figured that much out on my own. However with that said, the reason I ask is, the Fender Rumble 500 I went and looked at yesterday seemed pretty cheep, or lacking much physical durability. I can assume it's going to get dropped and knocked off the cab from time to time.

    Wow that's inexpensive for such a powerful little amp (but something on the B&H page makes my pc freeze up). How long have you been using it?

    I bought one of these: Behringer iNUKE NU1000 Power Amplifier (despite my pledge to avoid anything powered by Behringer) because I needed a spare while my GK was in for repair and I didn't want to shlep my 35-lb LH-1000. Worked fine. Pretty versatile - 300W/channel into 4 Ohms in stereo mode makes it a good match for my 112. ~1000W bridged (yes, I know they're Behringer watts...). 2-Ohm stable in stereo or mono. Light and $150. And that's the 'baby' iNuke...

    I also use a couple of the Behringer class D amps to drive monitors-a 4 channel INuke 6000 and a 2 channel INuke 3000. No clue about their real wattage, but they run my 5 Yamaha SM12 wedges very nicely. Never had any issues with either amp.

    I played a couple hundred gigs across a pair of Peavey IPR 3000w power amps. One of which is still working fine, although I've moved on to a much pricier custom class D high power amp.

    I’ve had the amp for about 3 years. It replaced a Carvin DCML2000, which was doing just fine. Really didn’t need the Crest.

    Sorry about the B&H Page. That’s just what came up on Google.

    ...do you regularly drop electronic equipment and expect it to have no effect on the equipment's functionality?
