One thing to add to here too...don't be afraid to play with the BMT settings. I know the real deal just has volume and cut, but if you dial it like a Marshall (3-4 on the bass, 7 mids, and 7 treble) and then cut to taste, it will give up a nice Brit crunch that lives between a Vox and Marshall. Once I got out of trying to reproduce this one as stock (5s on BMT), it allowed me to add 4x12 M25 IR and turn this a less gainy plexi with the volume down. I find that the Plexi models (which I love) still feel pretty gainy even at 4. You can play lighter and/or turn the guitar volume down, but I like to run full out but with less crunch (on certain guitars). In this case, it was a Tele Cabronita clone with TV Jones Power'trons. The AC20 12AX7 T dialed up as described ended up being my perfect fit for a Brit crunch sound. Don't forget to adjust the speaker parameter page on the amp block to match whatever 4x12 you throw on it. I my case, I used the Ownhammer Orange 4x12 with M25 speakers. Nice woody, grit tone.
