I wanted to achieve specifically Necrophagist's guitar tone on the album Epitaph . After trying every plugin vst that claimed to be an Engl E530 I ended up very disappointed because nothing was even close to that type of tone.
I decided then to buy the real deal and man , nothing compares to the real preamp. The response, the gain , the mid frequencies that instead of bringing in muddiness , make the guitar shine , that aggressive but smooth like butter tone.
Thanks to the separated low mids and high mids knobs and the contour button it's possible to achieve that angry lead but still smooth-like violin tone that I couldn't achieve with any other preamp , amp ,pedal or plugin.But it's not limited to death metal , the mids are the most important frequencies for guitars and there's where the 530 shines ; thanks to that, getting the 80's hair metal/ glam , heavy metal ,thrash metal or even Steve Vai's type of tone is a piece of cake.
By deactivating the contour button we get a kind of scooped tone that nails every metal / rock rhythm style we want to play and it feels like having a completely different preamp (in a good way) .
Then we got a low / high gain button that , when deactivated turns the preamp into a mid gain /overdrive machine giving us some kind of british vibes with Engl's soul and voice, very unique.
Last but not least the clean channel is so good and versatile, also possible to activate the high gain mode on the clean channel ,going from a pristine clean ,to an edge of breakup and overdriven sound just by pressing the high gain button on the clean channel.
Also the clean channel takes pedals very well, giving us even more options and with some delay or reverb through the fx loop the possibilities are infinite.
So, we got 2 channels that can be activated with a footswitch (not included) ,lead and a clean one. Each channel can run on high and low gain mode , that's like having 4 different channels and then with the contour button (that works for high and low gain) on the lead channel we have 2 more voices. In the end, from 2 channels , the versatility of this device, allows us to access to 6 diferent "subchannels".
But, it's not over yet, the e530 has a built in power amp in the front of the preamp. It's important to know and remember that in order to connect to a guitar speaker cabinet, we must set the switch to speaker cab on the back of the preamp and plug in to the headphones out a stereo cable to avoid damaging the power amp.
I'd buy it again and again a million times if I had to. The versatility and uniqueness of its tone is something that's hard to find on another piece of gear and for less than 600 euros / dollars it's undoubtedly a must have for any guitarist.
It's obvious why Alexi Laiho (Children of Bodom) or Muhammed Suicmez (Necrophagist) have chosen this preamp as their main rig.
