Hello, I recentely purchased a Peavey T.B.Raxx Tube Bass Preamp.Sounds great, but the Raxx doesn't have a direct out on it. It has 2 jacks on the back. A high output jack, and a low output jack. Is their an external device I can buy so that I can send the output of the raxx into the P.A.? Thanks, Greg P P.S. I finally found the preamp that has the sound I was looking for. Nice clean bass tones, and awsome tube overdrive. Incredible overdrive. I highly reccomend this preamp to anyone who is thinking of buying a preamp. It is discontinued but if you find one, check it out.
