I have the first generation SpiderValve and just picked up a used FBV Shortboard MKII. I used it for the first time today. It flashes when you change the bank up or down because it wants you to select one of the A-D presets for that bank. That way if you are moving up or down more than one bank, it doesn't change to a preset for each bank as you go up/down to the next one. I didn't even realize there was a MKI & MKII Shortboard until I looked at my MKI 2x12 manual and noticed the Shortboard diagram only shows a FX Loop switch (which it says turns the noise gate on/off), while the Shortboard II has the Function 1 & 2 switches. Since the Function 1 light switches on/off when you step on it, I'm assuming that's turning the noise gate on and off. I had the volume really low so there wasn't much noise to eliminate, and I didn't know what Function 1 or 2 was supposed to do at the time. Stepping on Function 2 didn't make the light go on/off so I was wondering what it was supposed to do. Now that I know there's 2 versions I'm assuming Function 2 doesn't control anything on the spiderValve MKI. Oh well, no biggie. I'll have to crank the volume up with a distorted preset and confirm it sounds like it is switching the noise gate on and off.
Hope that all makes sense and helps.
