Managed to snag an RR24 finally, and past recommendations have been either Miracle Man or Cold Sweat to replace the single EMG 81. My concern is that those choices may be too hot to run with the ESP MM-04 active boost I want (a la Alexi Laiho). I like the way this RR sings more than my other one, but the EMG seems lifeless and sterile. Still running the same Rivera TBR-1SL amp and Hughes & Kettner 2x12 w/ Vintage 30s, a newly acquired ISP Decimator Pro Rack G noise gate/suppressor, and I have a Rocktron Intellifex blackface in transit. Not trying to get a super saturated high gain sound, more just tightness and piercing harmonics, but without losing that warm, singing tone. Leaning towards the Rebel Yell, but looking to hear what you guys think, especially since this is a brighter and punchier guitar, and will be my first Bareknuckle swap.
