just got this little guy and am loving it with my pbass and upright. i have a passive fender pbass and although i really dont need to overload the input the manuel says to get it to overload on the hardest played notes and then back off it a bit for optimum performance. my problem is i cant get it to overload. i guess my pickups are not hot enough, but i put a sadowsky preamp in front of the amp and still cant get the light to come on. the sadowsky really boosts the signal and was really surprised that i couldnt overload the input with that thing. like i said before i really dont need to overload the input because i have been able to get great tone out of it with both my basses, just curious as to why i cant overload it. any suggestions?

i have tried all kinds of variations with the gain and volume. i have pretty much kept the master at 1200 and had the gain and volume maxed and every where in between. eq is 1200 bass, 900 mid, 1000 mid freq, tremble 1200. im playing it through a wizzy mline.

turn the gain up and volume down, that will help you "clip the preamp". the preamp is designed so the louder you have the preamp volume the harder it is to overdrive despite where you set the gain, so gain high and volume low will "heat up" your signal, i think anyway

maybe thats it i guess i have had the volume about half way up most the time and have been trying to overload it with the gain. and when that didnt work i maxed the volume and gain instead of backing off the volume and uping the gain. i will try what you suggested later tonight before the kids crash.

well i maxed the gain and set the volume at 9 oclock and turned the master down to about 9 oclock as well. i did not run the sadowsky in front of it. still no light, but that is a great tone. i have a kramer bass with a dimarzio pickup in it that is quite a bit hotter than the fender. too late to try it tonight, kids have crashed. i will try it timorrow with the kramer and also with the sadowsky. the fender is the first one i have owned, are the pickups usually fairly weak on a MIA p bass. i dont have a problem with the sound of them at all, but i had a g&l l2000 before this one and the pickups on those are really hot, really to hot for my liking. or maybe my light doesnt work. any fender pbass users with a shuttle?

I'm using a Lakland Skyline Glaub with the Fralin P-bass pickup. The output level on this bass is not quite high enough to overdrive the preamp. I saw the O/L light flicker maybe once or twice with the gain maxed. I'm wondering if this is normal for a P-Bass with vintage-style pickups?

I just got the Shuttle tonight and haven't spent much time on it other than a quick check through headphones. Initial impressions are great clean tones but a little less overdrive than I was expecting.

since you're not boosting anything in the eq section, in fact you're cutting mids, it is going to be harder to get the input LED to come on.

If you're getting the tone you want though, no problem. With an DB though, may I suggest something? Use the mid section to boost your low mids. Put the mid level at about 2:00 and the frequency at about 10:00.

This is might setting will all basses but, it works especially well with fretless and DB. I think far too many use the mid section to cut instead of boost.

thanks hasbeen, have not gigged this yet so all experience thus far has been in the bedroom. i will have a chance to gig it this friday and will mess with the mids in a live setting, so far solo i have found the mids cut to be more pleasing to my ear. i usually gig my upright but have been having so much fun with this amp i may go electric this week.

My MIA P won't really clip the pre amp either. The pup just ain't got enough output. Considering getting a boost pedal

OK I'm confused :confused:

I own three Fender P's a 60 with EMG Selects, an 08 62 reissue stock PU's, and an 08 American Standard stock PU's.

I also own two Genz amps. A GBE1200 and a Shuttle 6.0. I have no problems driving the tube front ends on either of these amps into clipping with any of my P's so I don't understand why some of you can't get yours to clip too. I assume there's not that much variation between amps, so they all should be pretty close.

I set mine up first with all tones flat and boost switches out. Channel and master vol off. I crank the gain till the clip light hits hard and then back it off for clean or give it another small bump for gritty. Then I move to the tone and volume settings. If I want a clean hi-fi tone with punch, I set the master high and run the channel lower, boosting the mids to where I like them and then working the low and highs. LF and HF switches as needed for room conditions or cabinet tone curve. My dirty setting is almost the same execpt I run the channel vol high and the master low.

One thing I can attest to and most GB users will probably agree is that if you're not hitting the limiter hard then you are not getting the full experience of using one of these amps :) IMO these amps love to be pushed especially the Shuttle 6.0. The limiter circuit that Genz uses is by far the best thing about the amps. It works in a very controlled and musical way, almost tube like I think. It actually makes the amp sound the way it does. Which is pure kick a..

Now the SS channel on my GBE1200 is another story. It really doesn't go to clipping with any of my basses. Which I like because I can get two entirely different tones out of the GBE1200. I don't know if it's designed that way or not but it works for me. I do know specs on the 1200 say that it has two channels each with different voicing so maybe it's normal for the 1200.

Just my .02

Keep Low :bassist:
