Oh my God.
We finally rehearsed and I could play my baby through the Engl E650.
And it is the sound. It is there. Using the neck pickup, it is so easy to dial in an incredible Blues/Southern Rock sound, and the bridge PU gives me a hard rocking classic Iommi tone.
Everything has changed. The tone pots don't make everything sound mushy and dark anymore when turned down, but rather seem to emphasize other frequencies (subjectively). almost every combination makes sense.
The sound is sweet, tight, quick and aggressive.
For those of you who only think of modern metalcore amps when they hear Engl, I gotta say that the Blackmore model is special. Most Engl amps are too modern and heavy sounding for my taste, but this one has classic tone and is just an amazing amp.
My initial fears that a full mahogany might sound bassy and mushy with Abraxas turned out ot be unsubstantiated.
All the frequencies are there, and it just rocks. The Abraxas, along with the other modifications, turned a guitar with a very good wood sound into a true tone beast.
Seriously, if somebody came up to me right now and offered me a mint 59' Paula in exchange for my worn, mistreated SG, or as much cash as you get for Paulas these days, I would not do it, hands down.
I spent a decade making this my guitar, and it has just the tone I want now. Tone heaven.
As far as I'm concerned, players of (not too dark sounding) SGs can add the Abraxas to the list of perfect pickups.
