Before I recently bought a Rumble combo, I used my Peavey Databass combo for about 15 years. Fantastic amount of welly for its size. I had to re-cone it a couple of times - mainly through wear and tear as I gigged it a lot. It's still sitting there as a spare. It's not worth selling as there is so much quality second hand gear at very reasonable prices out there. However in it's day it was very hard to beat for power/size. I know of at least two people who have sought them out on ebay after hearing it.
Unfortunately these days, modern combos beat it hands down - especially on the weight and also the clarity. As for reliability, that remains to be seen. The Rumble has already been back once. I'm not expecting it to be as bomb proof as the Peavey, but then a new one would pay for itself within a couple of months they are so affordable.
It's just a shame that you don't get the build quality that Peavey have, and that the company now seems in such decline. I'm fond of mine but just can't bear the back strain any more. I wish there was a modern (light/powerful/clear) Peavey to replace it with.
