stevie Posted September 4, 2018 Share Posted September 4, 2018 Thanks for the speedy response. I think that's a very good move. Now that I have your attention, Mr Ashdown ..... Would it be possible to buy and retrofit the aluminium chassis? Quote Link to comment Share on other sites More sharing options...
uk_lefty Posted September 4, 2018 Share Posted September 4, 2018 The only slight drawback, and I mean slight because as far as I know most amps do this, is that to get the full oomph you need two cabs connected. I've somehow got a 500w 15" Rootmaster cab which is likely to have been from the 500w combo unit or a special order, but I can't run with just that cab to get the full oomph from the amp. From time to time it would be useful to flick a switch and give the full beans in to one suitable cab rather than having to run two. Again, as far as I know most heads are set up like this and if it were as simple as flicking a switch then I'm sure that would be the norm...

I'm afraid not, layout has changed slightly inside as well so EVO internals won't fit into the new chassis sadly Quote Link to comment Share on other sites More sharing options...

Awesome, that makes a lot of sense! Did the original 500s have the metal screening inside like the original 800s? I remember reading somewhere that it wasn’t actually necessary but you did it to “over engineer” the EMC essentially, same for the fan and cooling..?

stevie Posted September 4, 2018 Share Posted September 4, 2018 (edited) Shame that we can't retrofit the new case, but the main thing is that the amp is fundamentally the same - only lighter. Edited September 4, 2018 by stevie Quote Link to comment Share on other sites More sharing options...

It’s been covered many times before, the difference between the output and 8 and 4 ohms is so negligible as to be moot, it is the extra speaker area which is making it produce more volume Quote Link to comment Share on other sites More sharing options...
Lozz196 Posted September 4, 2018 Share Posted September 4, 2018 Well having gigged my RM-EVO at the weekend I wouldn`t say it`s heavy, but 2kg lighter for the newer version, well if I were doing gigs using public transport I`d be all over the RM-EVO-II like hair on a bear.

Tried this at last night's gig, I've never used the pre-shape before in my many years of Ashdown use, but it certainly worked. Ibanez SR506, ABM 600 evo iv and Barefaced Super Compact and the result was a rich warm sound that sounded great on stage and out front, apparently. Good tip!

Yeah, for some reason your post floated into my head while I was setting up last night and so I tried it, and didn't touch the amp again until I switched off at the end of the gig. Lot of compliments on the bass sound from band and audience. Quote Link to comment Share on other sites More sharing options...
Lozz196 Posted September 9, 2018 Share Posted September 9, 2018 Yep that woolly-ness that people associate with Ashdown is way off the mark imo. Sure they can make that sound, but it`s not all they do, I find them to be very flexible. I get my eq from my Sansamp Para Driver as I use a lot of shared gear etc, but I can get very near/virtually there on my Para Driver sound from both my RM500 and my ABM600. Much more versatile amps than many give them credit for. And a lot more cost effective than a lot of other brands too. Quote Link to comment Share on other sites More sharing options...

The other factor to take into account is that if you play very loud, the single cab my be approaching power compression so the difference may seem even more. Two cabs my not be suffering from power compression nearly as much. Quote Link to comment Share on other sites More sharing options...

Oweneatonmusic Posted December 6, 2021 Share Posted December 6, 2021 Hey you guys, I own an Ashdown RM 500 evo 2. I've ran into an issue where the amp is making a whistling noise. It's not the fan, I am sure it's within the circuit. Has anyone else had this issue? Quote Link to comment Share on other sites More sharing options...

Yes mine did that but only when ironically I pushed the mute button. I took it to Ashdown and they sorted it. I’ve no idea what it was as it was a couple of years ago and techie stuff is a bit beyond me. Quote Link to comment Share on other sites More sharing options...
BassAdder60 Posted December 6, 2021 Share Posted December 6, 2021 If you can get it back to Ashdown U.K. and they will sort it quickly and without hassle too Quote Link to comment Share on other sites More sharing options...
