Since the 1970s, every serious rock and roll guitarist has used Ibanez’s Tube Screamer distortion pedal. I’ve played with an original vintage pedal and some of the later models that use digital processing and let me tell you: the original still remains king. The tone is so perfect for a humbucker and a Marshall that it’s truly scary.
Unfortunately, the remaining pedals from the ’70s don’t come cheap. Luckily, you can make your own through the magic of the Internet and Instructables. You’ll have to do some PCB etching, but don’t let that turn you off. Keep in mind that because this is DIY, there are no rules about having a pedal that goes past 11.
