Based on 16 ohm Celestion Marshall Vintage speakers loaded into our Rock-Box cabinets, the combination is something that at times defies logic. It's smooth on the top yet it's detailed. It's forward yet it's girthy. It snarls in the upper mids yet it's never pinched, nasal, or harsh. It has great body in the lower mids yet it's never wooly or muddy. The low end punches with authority yet it is controlled and tight. It's great for the heaviest and the cleanest of tones. This is something that no matter your music style, you need in your tone arsenal. The density of sound, with everything you'd want in a guitar tone and nothing you don't, feels meticulously calculated, yet it's completely natural and organic. This collection will stand the test of time. You owe it to yourself to pick this one up and just lose yourself in your instrument and your music.
