The BSM RG Rory Gallagher tribute model is basically a BSM HS-Custom, modified to nail Rory Gallaghers signature tone, known from his famous recordings like "Big Guns" or "Lonesome Highway". Compared to the HS-Custom, the RG Rory Gallagher tribute model offers more gain for a more punchy sound with a good crunch. The RG Rory Gallagher tribute model, includes the same volume control, like Blackmore's modification on his treble booster. When dialed about halfway, you will achieve Gallaghers sound from his early records like "Deuce", "Live in Europe" and "Against The Grain". If you use a guitar with PAF style humbuckers, reduce the guitar's volume from 10 to 7 and set the PRA's volume to 50% to get this earthy, rough early/mid 70's R&B sound from the "Faces" (Ron Wood on guitar and Rod Stewart's vocals).
