And here an image of the unit: http://www.solodallas.net/wp-content/ga ... /mr292.jpg
Please note the "Monitor" volume and output 1/4 jack output. This is where the unit would output with a boost (probably even on the back panel, will have to check making it work and/or opening it up and dissecting it, both of which I will do).
While certainly it can't be a "magic" boost, and many types of clean boosts are available on the market today, I think that being able to exactly
dissect the components of this boost (and most of all, the exact amount of db it can output boosting a Marshall input channel, and what frequencies it will boost as well
) would allow "us" to obtain the so much subtle Angus' tone of those very years.
I have made also attempts at finding why "Let There Be Rock" (the album) would differ from previous albums in terms of sound (Angus) and it is now clear to me that this was AC/DC's first attempt at using the Schaffer Vega in the studio.
The result is an over-boosted Angus over a 1959 Marshall head, both for rhythm and solos, scattered all over the album.
The famous "raw" sound of that album is in fact a direct consequence of Angus boosting his 1959.
This has never been documented, nor it has been talked about before, therefore I am glad I can make mention of this myself seemingly for the first time with a certain degree of certainty.
For all AC/DC fans out there, I think this is pretty interesting.
I have an audio test I made myself, I am linking it here for you to listen to.
It's clean boost I have (no brand, it's custom made) on input number one of my 1976 1959 Marshall head through a 1973 4x12 1960B with G12H30s installed.
I believe the album sported G12Ms, not G12H30s, but I can only use one cabinet at a time as I have little room where I am now.
