I have been having good luck with my Tech 21 Acoustic DI and Bass Max pickup going direct to the PA (mixing board EQ flat). So now I'm wondering if there is any problem going straight from the Tech 21 into a QSC (or similar) power amp without another preamp in the chain. Does anyone know if this is OK? Is there any electrical problems with this thinking? Since the DI will do tone shaping before the XLR out, I think I can take the line out to a power amp and 1x12 cab and still run the XLR to the board. A good clean power source can be had pretty innexpensively and without a huge weight penalty if I don't need another preamp.
