Great TS style pedal, which is much more versatile than the original circuit due to the clean blend knob and the mod switch. Don't see any need for buying/keeping other TS pedals after buying this one. It can also do the Klon thing btw. The build quality is amazing. The only downside is that it takes a bit more real estate on the pedal board. I use it primarily as a boost, but it can do a great job as a standalone overdrive, too. It's worth every penny.
