It's a line 6 bass pod pro. Model number is unavailable at the moment but I can let you know tonight.
Ok, that's all I need...
Start with the volume low on your amp and POD.
1) connect your bass to the POD input. Make sure the switch above the input is set to Bass.
2) connect the MODEL output of the POD (back of POD) to your amp input (front of portaflex). Set the switch next to the output on the POD to LIVE.
3) on the POD choose "tube preamp", and set the gain at 9 o'clock, bass mid and treble at noon, compression off, effect off for now.
4) bring up the volume of your amp a bit. Now bring up the volume of the POD until the thresh light starts to just blink / flicker. This should sound nearly the same as if your bass was plugged directly into your amp.
5) now, turn up the POD output knob until the thresh light is on most of the time you are playing. At this point you should be driving your amp into breakup, or saturation.
From here you can do a few things on the POD:
- turn up the gain, balance the output.
- just turn up the POD output, just be aware of how hard you are pushing your portaflex.
- add the effect called "pig foot" and turn up the effect knob as you like. This is a booster.
This is just the beginning, you can go way deeper from here. It should give you an idea of your amp driven. You can mess with all of the POD settings from here as well, just to give you an idea of what other distortion a sound like.
The manual is a really annoying read, but there are a couple of ways to hook it up and get some decent tones from it. This way you can get a sense of what sound suits your band and have us help you find a simple pedal to get you there.
