Marc:
Congrats and enjoy. I'll second Paul TBO - let the tweaking begin! One piece of advice: Tweak it one channel at a time. For example, I use mine in the mono mode. In this mode, think of the SF-2 as a 3 band mixer - one dry channel and two filtered channels. I turn down the gain on the two filtered channels all the way so I'm hearing the dry channel only. I then set my amp's tone controls to get the sound I like best. Next I turn the dry channel gain back to 0 so there is no sound at all. I then turn up the gain to one of the filtered channels and find a frequncy in the high end I want to accentuate that sounds good (using the filter set at either high pass or band pass, whichever gets me what I like with the particular guitar I'm playing). The gain on this channel then goes back to 0 again and I do the same with the second filtered channel, setting it for a low frequency I like, (low pass or band pass filter setting). I then bring in the dry channel and high end filtered channel and mix them all together to taste, adjusting only the gains. If using the SF-2 in stereo mode, adjust accordingly. This one-at-a-time method really helped me get a handle on what can easily be an amazing but overwhelming piece of equipment. Have fun!
