I've found myself GAS'ing more and more lately for vintage pedals. Call it magic, mojo, whatever, I just am starting to prefer old versions of pedals that are still produced, albeit to more modern specs. It started with a big box DMM, then it was the Maestro Stage Phaser, then it was a DD2 over my trusty DD3, and now I'm checking out Echoplexes and vintage Tube Screamers. I still use plenty of modern pedals, but I'm wondering about the incorporation of the vintage pedals into a more modern, practical set up. I'm not a collector of pedals per se, although I do collect other things, but the collector in me wants to keep them original spec and not modify them. I have three questions: 1. Is there a difference in buffers from older Boss, Ibanez, etc... to the current version, or is it essentially the same buffer found today? And if so, do people actually prefer one over the other, an example being the way people actually like the way an Echoplex preamp fattens their sound up. 2. What are people's opinions on modifying vintage pedals, even a simple modification like making it true bypass? 3. Do you do anything special to incorporate your vintage pedals into your set up like adding a looper, etc... Do you find that older pedals don't always get along with newer pedals, or do you just treat them the same as you would any other pedal in the chain? Thanks, and looking forward to reading other peoples thoughts/opinions on this.
