IMO, Steppenwolf were at their best during the "Monster" and Steppenwolf 7 albums. Larry Byrom was their lrad guitarist. He played a Gibson 335 through an Ampeg VT 22 when I saw them at the Fillmore East way back when. I was impressed. Back in my HS daze, I played this with my cover band............. https://www.youtube.com/watch?v=0mGKXG6TH7A Then there was Kent Henry on lead guitar (for 1 album, I think)............
