I am getting ready to buy my first real Trace, an AH250 GP 12 SMX (?) I need to know if I can use this as a pre-amp for recording by simply unplugging the speakers? Will it hurt this solid state amp to run it without any load? I have been playing Bass for 20 + years, and it is time I stepped up to some serious gear. Tangential Gibson connection. I worked for the Gibson Acoustic Custom Shop from 89 to 94. Built great acoustic guitars, and made my own bass while I worked there. Have been playing Hartke 3500 for years, ( unfortunately) but after I plugged into a Trace GP7 head last month I knew that I finally found my sound. Any advice or dire warnings for someone about to buy an SMX? I have lurked and read almost all of the prior Trace Elliot threads, I think I am making a decent choice. I am merely a weekend warrior and I am ready to step up to great tone. What do I need to know as a new Trace convert?
