    So i recently got my ampeg pf500 and i put everything flat and it was sooooo quiet for 300 watts at 8ohms. my gk head is much louder at 140 watts at 8ohms. i did my gain setting and ended up on 2:00 before it started clipping and still it was very quiet. I used the same speaker cab for the comparison and the gk is by far much louder. I turned the master volume on the ampeg pf500 from 12 to 3:00 and it came to life and was immensely loud and rich. my question is, are these safe settings? Im scared of running it to hard and it failing on me, im running everything flat except a bump in the midrange at 3:00 with the selector on 2 is this gonna fry anything?

    and to be clear:
    The 15 db pad was NOT pushed in
    I used the same bass, cable and cab each time

    Don't be scuuur'd

    Longer-term owners can and surely will answer, but I had a PF500 for a short period and also found that the master wasn't linear and most of the juice was on the right side of the dial. As long as your cabinet doesn't complain, you should be able to dime the master without worrying. If you have to do that, it's not enough amp for you, but it shouldn't fry anything.

    With different amps, you can't necessarily go by the knob position, but I know what you mean.

    So, does 3:00 give you what you need? If so, I'd think you're fine. It may well be that 50% of the volume is between 3:00 and full.

    I just got one of these amps as well and hooked it up to a single cab. It was super quiet until my guitarist found a button that drops 40 db engaged. Depressed that button and got a serious volume boost and was able to get a tone. You do have to crank the master volume for sure though and then play with the gain and compression to find a sweet spot. I find it helps to have both ultra lo and ultra high engaged as well.
     
  7. Ultra low and ultra high?

    I found these settings to 'thin' out some of the punch of my P bass. When I engage the ultra low it leaves the thud ok, but takes away the boom. Smae for the ultra high, it just eats the presence to my ears.
    Maybe I'm doing something wrong though...

    Either way, love this little amp!

    Zombie thread, sorry guys, but beats starting a thread when one already exists :).

    I got mine yesterday and also felt I had to push the volume knob at least at the noon mark to get loud enough to be heard in our 2 gtr-bass-drum set-up, with the gain also around noon. For now, I had the lo switch ON, EQ knobs all noonish. It sounded good enough to get grins out of my bandmates, but I'll work some more on the weekend.

    The volume pots on the PF-500s aren't linear. You really have to crank them to start getting volume. When I had mine I felt like it didn't even start to increase the volume much until at least 1:00 or so.

    Ya, knob position means nothing on any amp. What counts is results.
     
  11. Am I the only guy that doesn't use the compressor on his PF500? I just never used a compressor.

    Never touch it on my PF800 or 7 Pro...or any amp with one built in.

    Knob position is meaningless as a reference. The PF500s like the master cranked up.

    When I owned a PF800 I never touched it either.

    Here is something Bassmann79 posted about 4 months ago with a picture of the settings. Notice how everything except the treble is pretty cranked and the compression is at 0. I think there is also a SansAmp somewhere in the mix. Give it a shot and see what you get.

    You guys running your pedalboards through the backpanel's FX send/return jacks, or through the frontal input ? I tried both and still prefer the front, but I'm curious...

    I didn't use it much. There were a few times when I added maybe 5%.

    Input ALWAYS! I hate loops. The only thing I ever use them for is to bypass internal head preamps just for experimentation at home.

    That's pretty close to what I always set it at actually, the mid switch is usually on one or two, if I set it to fit l four or five I usually cut a little bit, but then that sound fit with my previous band.

    I've never had trouble with getting a great sound with my 500, and it's no slouch either, but unlike my old Warwick that was very HiFi and clear, this amp seems to excel at a higher gain grunty kind of sound. It's very versatile though, the eq makes me think a bit of an svt with its layout.

    both/all...

    I use the 4 cables method:
    1. Bass to GT-10B INPUT;
    2. GT-10B LEFT/(MONO) OUTPUT to PF-500 fx loop return;
    3. PF-500 fx loop send to GT-10B EXT LOOP RETURN;
    4. GT-10B EXT LOOP SEND to PF-500 front input.

    Interesting... I've never tried that and don't even recall reading about someone doing that. What's your end result ?

    4 cables method lets me choose which preamp to use: any of GT-10B's many preamps or PF-500's preamp. And if I'm using PF-500's preamp, I get to choose where to put it in the signal chain, as if it's a part of GT-10B's.
