Thanks for that steve.
And don't be put off by my Noobie status. TaySte, Higgie and Toasted all know me so they'll tell you how much of a safe guy I am . I'm also a regular on Talkbass and I have something like 18 feedbacks on ebay all 100%.
Actually, option 3 would be better than 2. I just realised you'd have to press two switches if you wanted it on with a fuzz with option 2. Option 3 is definetly better if you don't want the buffer on all the time.
