To be honest, Rectifiers never have been my favorite amps. But this plugin sounds excellent. It also seems to sound a little bit different to some other Dual Rectifier simulations, which I've heard or tried up to now.
I've noticed a more dynamical reaction, a generally more aggressive, more transparent sound with less fender-like politeness and compression, which I noticed on other Rectifier simulations, instead with more of an almost British voiced directness and rawness, nevertheless the tones still remain typical, excellent Rectifier tones.
Apart from a lot of other great tones for me the real secret weapon of this plugin is - really surprising for me - the Pushed voicing of channel 1. It not only creates the expected decently crunched Tweed amp tones, but at higher gain settings you also get some (for a Mesa Boogie) astonishingly great sounding and very dynamically reacting JTM/JMP Plexi tones, with the additional advantages of a really good working tone control plus even more fine-tuning options due to the very effective Bold/Spongy and Tube/Diode switches. Maybe with more of this typical Mesa Boogie low-end, but this is not necessarily a disadvantage, and also can be reduced easily if wished by reducing Bass.
This voicing alone would be worth the plugin. In fact it was the main reason for my purchase.
I also noticed, that the 3 different voicings of channel 2 and 3 seem to be better balanced than on some other Rectifier simulations, so the different voicings also seem to be better usable, as they all have their different, special qualities.
