I'm not gonna come on here and pretend I'm tech savvy....far from it. Have I been playing a long time.....yeah, since 1967. I've been a tube guy for just about that long, but the dark side got me and I bought some S.S. amps that I found were pretty good.....but they never had that warm, buttery sound. The Martin doesn't mask or change your sound, IMO it takes the harsh out of my Amps that are S.S. Does that make sense to you guys? I know I use my aluminum bass cabs a lot more...kinda like the best of both worlds.
