Hi folks During most gigs I swap back and forth between a Precision and an EUB. My amp is an SVT-PRO III with one input channel. The output of the EUB is a blend of magnetic pup and piezo, powered by a 9v battery. Problem is, the EUB's output is tiny compared to the P. So far, I've been switching in my Sansamp to lower the P's gain before it gets to my amp - that way, I can get them pretty well matched. BUT... but the signals going into the amp are so low the input gain has to be cranked. This inefficiency means I don't get as much volume as I should. Plus, I suspect the EUB signal isn't great by the time it gets to the amp. I tried switching it around, i.e. using the Sansamp to boost the EUB, but, even when it's cranked, the level is still a little way short of the P. Any suggestions? I get confused re: impedance etc, but for what it's worth the sound guy I work with says the EUB's signal is an instrument signal, albeit very low. I have my eye on Bob Gollihur's preamp page, and the K&K stuff in general. They're not too expensive which is a bonus... would that boost the EUB to P levels? Plus, if I did, would the K&K do odd things to the P''s signal meaning I would have to bypass it, or would the signal pass through unchanged? Thanks for your help!
