Chew on this for a second. I went to Gelb Music in Redwood City to try the Accugroove Tri 210L (you know, with the impedance switch) and had a rather interesting time. The cab is light and loud, but the tone I got from what I believed was a high-end rig was kind of. . . . . Here is the rig: Mesa Big Block 750 Accugroove cab Zon Sonus 4 Where is the weak link? The bass was set slightly above flat on the controls and the Big Block was set at a reasonable gain and master with the EQ set at 12 o'clock. The tone just. . . .was nothing special. Any ideas? I want the cab, but maybe I should wait for the new Mesas?
