Also yes the trivium guys were originally planning on using the box of doom for the megadeth tour that just started. They even tracked the new album with it originally, however josh was not happy with the tone, thought it was alittle boxy in the mids, no pun intended. They ended up retracking all of the rhythm guitars with my Mesa OS cab with a 57. Leads on the new record are an SLO, with I believe still the box of doom
Though, with a redback 150 speaker. the problem with things like the box of doom is the whole thing is the speaker/cabinet. It’s not nearly as solid as a real cab on the back baffle, which can lead to some non pleasing results.
The IR they are using live and during streaming is an IR from nolly getgood, a 57 on one of his Mesa cabs.
