Thanks again.
Bolo, the sound I get going straight to my SWR rehead without an additional outboard preamp is thick and beefy, with plenty of volume. That's why I don't understand why most people I have talked to have mentioned line impedence. I have noticed that most acoustic guitars with Piezo's have an onboard preamp with battery, but the sound I am getting is just fine...I just kind of wondered if there was a major difference in tone or not if I used something before the combo amp.
As far as the line 6, Bob...it does sound great and is basically what I have been using. Unfortunately though, our band plays routinely in small, dark places...(out of sight and out of mind I guess!) so keeping my gear to a minimum is crucial. Dangling cords are not good for my application. For most gigs, I have been doing this: King Doublebass (all guts)with Rockabilly Pups into K and K preamp straight to the amp, or straight to the line 6 (after the preamp) or Steel strung upright with Bass max direct to line 6, or just straight to the amp.
For some reason, I am getting a great tone no matter how I arrange it. Whether I use the preamp, the line 6 or just go straight, the only difference seems to be with volume, but it is not drastic. In any combination, I get no line hum. I do get feedback only if I actually turn the front directly to the amp when cranked. Other then that, no feedback.
I don't undertstand fully why I am getting so few variations in sound/tone no matter what the setup, other then perhaps the bassmax just is a great pup?
