Being an old fart, I love the development of all the new mini and micro heads. I've been using my Little Mark II for years; it's never let me down, and truth said I've been pretty happy with the tone. But gigs are down this month, spring is coming, and I'm a little bored, which means it's time to screw around with my gear. I might as well try some new heads to see if there's something I'm missing. I play flats about 60% of the time, and even my roundwound tone leans old school (think seventies). Looking for warm, tight, and present. Probable candidates would be a Mesa Subway and an Aggie Tone Hammer. I would try Ampeg, but I just don't trust their build quality any longer (am I wrong?). Anything else I ought to be looking at?
