I'm with you... the ONLY effect that has never left my chain is my 20 year old Rat II. However, a couple of years ago it died, right before a gig. I was unable to find a vintage one on short notice, and the new ones suck, so I got a Maxon Distortion Master and tried that for a couple months. It's a great pedal, but it's NOT a vintage Rat! I wound up sending mine to Robert Keeley for his three-way mod. He recognized my breakage from a description on the phone - apparently a common problem with older Rats. He fixed it for free as part of the mod. Now, instead of a wonderful vintage Rat tone, I have THREE tones, all of which are BETTER than the original vintage Rat! Keeley's three-way Rat mod is truly amazing. Best distortion pedal I ever played.
