I get so caught up in stage rig details I often forget about the quality of the signal send to the mixing board. I'm usually using an Aguilar DB 659 pre which has a Jensen transformer signal-out circuit but sometimes I use my WT400 or a Carvin preamp (like the R600 but without the amp guts). Depending on the venue the mains are often carrying the bass sound for the most part and my stage rig is a monitor. I play (mostly) an MTD 535 with the bass EQ pretty flat and EQ my stage pre to get what I want on stage (running a preEQ signal to the board at the soundman's request). I'd like some input about what those of you who routinely have PA reinforcement think about sending a signal to the board. Most serious pro sound companies seem to prefer a good direct box (which they supply)???
