Cool, glad to hear your getting something good. Don't give up 'cause if you keep trying I'm sure you'll find tones worth playing.
I just changed the way I'm building tones a little bit and am finding new and different variations of what I had been using before. Using the latest flash update 2.10 and set the Mode to Combo Front, Focus to 670hz, and Low & Highs to -50. Then I set the patch like Meambobo's Guide suggested. Setting up the patch in path A, muting path B and panning path A to center.
Then I put Mod, Delay and Reverb after the mixer and have Input 1 source set to Guitar and Input 2 source set to Variax. The guitar in Z is set to Auto. Usually I use the Dynamics and Distortions before the amp in Path A. The PAD/Normal switch next to the pedal is set to PAD but sometimes I switch it depending on the guitar I use. Also the 1/4" Line/Amp switch next to the pedal is set to Amp.
I use Amp Pre's often unless I use the Studio Direct into Headphones and/or use the XLR into the Spider Jam Mic section sometimes I use the Aux input on the Spider Jam. I've even tried using the Headphones out on the HD500 into the MP3/CD input on the Spider Jam witch sounded good also. I usually do not use a Cab model so that's set to "No Cab". Most of the time the amp volume is almost full open and tweak the drive turning the volume down if needed. The Master Volume is full open and I always set a volume pedal at the end of the chain.
With the Spider Jam I normally go guitar in, set the Amp to a clean channel. The Drive knob to 12 O'clock, the Tone stack knobs to 12 O'clock, Channel Volume to 12 O'clock, No effects, and the Master to 12 O'clock.
This is how I set up a basic distortion patch. Here's what it looks like.

I can share tones with you but there's a good chance they won't sound the way I intended them to sound, you'll more than likely end up tweaking them.
I was playing around with this one today check it out. Don't forget you may have to tweak it and don't be upset if you don't like it, we all have different tastes at different times and none of it is "Set in Stone".
Here's a patch I made with the Amp you were trying to use. I did this with cheap headphones but in the modes I talked about earlier, Try this Tone. Pictures below show you the settings.
