I spent the 99-bucks for a LR Braggs Gigpro preamp last week and have put it thru it's paces in the "bass cave" at the house and at two blues/folk gigs this weekend. I have a Englehardt EG-9/Spirocore weichs with Full Circle pickups. Here's my take on the unit:
* The high pass filter did not seem to be that effective at limiting the frequencies below the set point. I rolled off the lows at about 100 Hz - but that's a guess because the unit does not have a freq number indication on the case like the Fdeck HPF unit.
* The bass pot/knob was set below the center detent was did not affect the tone much. It seemed to add muddiness rather than bass. Treble was effective. There isare no control for the mids like on the K&K Pure preamp.
Now for the killer... Last night I was checking my FOH sound using headphones thru my GK MB500 amp into an old 4-track mixer. At first I had a muddy tone using the Gigpro. I then took the Gigpro out of the signal line an Lo and Behold, the sound improved dramatically. More clear and less muddy without the Gigpro in the line. I made several adjustment to the Gigpro and the amp gain to see if I could adjust the mix and to make sure I wasn't overdriving the input on the amp. After an hour of tweeking everything, I finally decided that the best sound was direct to the amp and into the mixer (low Z output).
I have now ordered a HPF from Dr. Fdeck and setting the Gigpro aside for set-in gigs with amps that can't handle high ohms.
I really would like any opinions from others who have tried the Gigpro preamp. Did you have similar problems with clarity or other issues? Thanks.

Now, about that preamp...
