    POD Mic Recording + DI

    Mute the computer monitors and see if the feedback goes away.

    POD Mic Recording + DI

    You'll want to set Input 1 to guitar and rout it only to signal path A. Set Input 2 to mic and rout it only to signal path B. Then use the mixer to send signal path A 100% left and signal path B to 100% right. Do not use any FX after the mixer cuz some of those will muck with the stereo separation. You now should have a single stereo output to your PC containing the guitar on 1 side and the mic on the other.

    HD500X 1/4inch Line/Amp Output

    Go here to see all my measurements and click on the link that says "Gains". From there you'll see that Line provides 6dB more signal than Amp. That's all it does. Depending on what you're plugging into, you may need to set the switch one way or the other - or maybe not at all. If the sound guy needs more signal, switch to Line. If the amp seems way too over-driven, switch to Amp.

    Trying to run an electric cello through 500x, bad tone?

    It sounds like the iLoud monitors from IK Multimedia may be perfect for you at home. They are basically really, really good computer monitors with very flat response. One thing my do with my acoustic instruments is play them really loudly thru the HD500 - loud enough that I get feedback. I hold the instrument up close to the speakers and thump the instrument. A dominant frequency should be heard. If not, turn it up more. I then use the Studio EQ FX (it has the best dynamic range, low distortion, transparent sound) to notch out that frequency. Then I turn it up again to get the next feedback frequency, instantiate another Studio EQ, and notch out that frequency. I do this 3 - 4 times. Nothing else is in the signal path. Just a bunch of Studio EQs. This way you get a nice balanced tone with no honking frequencies. But you'll need some nice balanced, flat monitors (like the iLouds, but there are others) for this to work well. You don;t want speaker resonances to muck with your cello resonances. The suggestion to set Input 2 to Variax is excellent. Also, you may need to adjust the input impedance. Depending on the transducer being used, you may need to max it out. An impedance too low will give you a nasally sound.

    HD 500 won't let me use just effects

    So, you're saying you can create and patch with an amp model and get sound. Them when you delete the amp model you get no sound?

    How long does (did) the HD500(X) last?

    I've had the HD500 for about 10 yrs and had to replace the USB port. Everything else is fine.
  7. And notice that using Codamedia's technique you don't need the AB switch anymore.

    HD Vintage Pack Specification ?

    Kroa, you're a EE? You'd enjoy this thread:

    Best gig bag for an HD500X?

    Yes, I remember the first few times it was quite a sung fit. It's much easier now, 4 yrs later.

    Frequency Response Graphs For Hd500 Eqs

    I just updated the OP with new links to ALL my measurements, not just the EQ FX. Enjoy!

    sudden howling sound

    I suppose that's possible. Howling is usually a feedback problem, so I'd ficus on that (although it is a simple experiment to switch those GND switches. Another idea, use headphones instead of the Yamaha speakers. Does it howl with that? It maybe feeding back from external speakers to microphonic pickups on your guitar.

    Switching amps in a dual amp setup

    Agreed, use the foot pedal to smoothly morph from one to the other.

    sudden howling sound

    Could you be using SPDIF somewhere in your system? Master volume doesn't control that. I don't think it controls the CD/MP3 input either, in case you're using that.

    Getting a unity gain line level output?

    Yes, the biggest oversight in the HD500 design was no signal level meter. The signal can get clipped after any of the FX blocks if you're not careful. But unless you're doing something extreme, and I doubt you are with an acoustic guitar, then you're probably fine. I measured the clip levels of the HD500's various IO ports and reported my results here. For example, for Guitar Pad = Normal, the input ADC will clip at 8.3Vpp, which is HUGE. You're active preamp output is probably closer to 1Vpp. Also, note that the gain from Guitar (Normal) to 1/4" out (amp) is -4.9dB. That is, a blank patch lowers your signal by 4.9dB! However, switching the pad to "Line" adds 6.1dB of gain and will largely restore your signal gain back to it's normal level (actually giving you -4.9dB + 6.1dB = 1.2dB of signal gain). All my data was taken with Master Volume = max. Reducing that will result in lowering your signal level (obviously). I have also measured the gain thru a variety of FX and listed the results here. This way you can account for those gains/losses as well. Finally, since you're using the Vintage Pre you may be interested in this thread, where I measured the frequency response of a variety of EQs. The Vintage EQ and gain & output level controls so you probably have to adjust both to get net gain = 0dB. In that set of data I used an input level of -20dBFS (to make sure I didn't clip anything) so for 0dB gain look for a -20dBFS output level. It looks like Gain = 50% and Output = 72% will do it. Oh, one more thing - once you start adding compressors and EQ then the concept of "what's louder" gets really fuzzy. Frequency response effects and changes in dynamics can make something SOUND louder even tho it may measure lower. So, use my measurements only as guidelines and places to start from.

    XLR output much lower than 1/4" outputs

    You can see from here that the XLR outputs are about 9.5dB lower than the 1/4" outputs.
