My band split up recently so took the opportunity to reassess my amp needs. I'd been using an Ampeg B410hlf with a GK Backline head. It was a good set up, very loud and served me well. However, the weight was not so much of a problem in that I couldn't heave it around, it was just getting a bit tiresome even getting it from my house to the car, which was only a very short distance.
So, I did some serious amount of research and after selling a few bits and pieces, mainly my old set up, I ordered a Rumble 500 combo. I'd previously owned the V2 350 combo and always thought it was a very much overlooked package...that's not to say it didn't have its flaws. I do like the Fender 'sound' and I must say I am duly impressed with the 500. It's a very well thought out package.
I bought the Rumble from Thomann in Germany (I'm in the UK). They're retailing them for around £400, all the UK online retailers have got them at £480. I ordered the combo late Friday afternoon and it arrived Tuesday morning. I was more than a little impressed.
Comparing it to the V2 there are some marked differences and improvements. The V3 is significantly lighter and made from better materials. The V2 was made of chipboard. The V3's styling is much better, the V2 was very workmanlike. The V3 has a lovely vintage look and the layout is very to much to my liking.The driver configuration is now vertical instead of horizontal, dispersion on the V2's could be an issue, hopefully this will resolve some of that. The other major improvement from my point of view is the fact you can now add an extension cab. This was a real weakness for the V2 and may have been why it wasn't that popular.
How does it sound? Out of the box with no eq adjustment it sounded really nice. It was clean to my ears but also made my Jazz bass sound lovely and woody. Tweak the eq and the changes are clear but also subtle. It can go loud, I've only played it in the house but I made a quite a few ornaments and bits of furniture rattle. Clearly it's not as trouser flapping as my previous Ampeg 410 but it'll definitely do a gig like the old V2's.
The voicing presets are a good feature, particularly the Vintage one, it gives a lovely valvey warm tone. (Bright, that brightens and contour scoops mids). They all adjust the tone in a measured way, it's not a harsh or brutal change. The same goes for the horn. Switch it on, you to get the highs but you don't get that horrible harshness you can get. The overdrive isn't stupid either, it overdrives and doesn't do an impression of some metal distortion pedal.
It's finished very well. The tolex and grill have got a nice feel, the hardware feels solid. The handle looks alright
.
This combo absolutely suits my needs and it sounds great as well.

And here's a pic of my previous Rumble 350. I really do regret selling it to be honest.
And just for the hell of it here's my old Rumble 350 with my old Ampeg and GK. I was in a prog metal outfit for a short period (didn't get to gig) and experimented with sending effects through the Rumble and a no effects signal through the Ampeg/GK. It was thunderous

Please ignore the guitar.
