Marshall JVM210 100W & 50W With TubeSync DIVO OV4 Installed

What is my opinion about the TubeSync Divo OV4? (Charlotte Mijnders – http://www.charlottemijnders.nl )

Well, it has improved my sound, it is much tighter than before, on both the amps it looks like the tubes are matched much better and are pushed to their best performance.

The overall sound is more defined, tighter, more dynamic to my opinion.

On my Jvm210 I have 2 El34’s and 2 6550’s , I can switch between them and they sound as mentioned above, but the best thing is combining all the tubes together, that makes a great sound, more tight bass and bass/mid response of the 6550,and beautiful mids and mid/highs of the El34 on top of it, I like it!.

That is a great option of the Divo, that you can combine tubes in this way.
