I've been able to get some nice sounds using my Sans BDDI in conjunction with my Peavey Basic 112's pre amp. I like to crank the low and high mid knobs on the Peavey while blending in the Sans, which I haven't found an affective way of boosting mid range on its own. I've just purchased QSC RMX 1450, and will now be using the BDDI for all my tone shaping. I want to pull in lots of low mid. I guess this is yet another "What are your settings on your BDDI," but this one focusing on NOT using a bass amp's pre, but going straight into a power amp. I'll go into 2x12 or 2x10 cab from there. I like tight punchy lows. any advice, vets? thanks as all ways, f n o r d !
