I've had my current rig (peavey t-max combo and 410tx) for about 5 years now and I was thinking about upgrading my gear. What would be a better first buy: a new preamp or an upgraded 410 cab? I eventually want a separate preamp/poweramp setup but I don't know where to start. I was thinking about an acme b4 but they cost a pretty penny. What do ya'll think?
