I just sold my LMII, Ampeg 8x10, DB 112, and just bought a DB212 I really wanted to get an ampeg head so I tried out the AG500 it was way too dry, so I tried the DB751 and LOVED the tone. HUGE sound.. With a HUGE price.. So I sold my LMII on ebay and its new head time.. I play two styles of bass, a very agressive, brittle tinny flea like sound, and a very smooth warm coldplay like tone. My Sterling H/S works great for this, can do warm or brittle. The Aguilar DB 12s Sound great for both also. But for the head? I loved the DB751 and I should go back and give it a try for a thin brittle tone. But the Price is wayy to much, Ill buy a used DB750 for around 1300 [thats still alot] As for my little mark, it did the warm tube sound great, which is why I bought it, but it wasn't great at the tinny sound, but it got me by. I tried the LM Tube and couldn't tell much of a difference between solidstate other than volume increase with the tube and a better breakup. What would you do if you were me?
