Earlier this year, a good friend of mine let me borrow his Keeley modded TS9 Tube Screamer. Now, if you know me then you know that I LOVE PEDALS! It doesn't matter what it is, I want to try 'em ALL! Now, I have a TS9 and I've used it on my pedal board for a long time now, but I was really excited for the opportunity to give this mod'ed pedal a serious test. So for the past few months, I've had this Keeley in my pedal board. So what's the difference between these two pedals, you may ask? Well, I figured I had waited long enough to do a side-by-side comparison between my stock TS9 and the Keeley Screamer...enjoy.
