One is a Timmy, set to very low gain. The other is a Fulltone Fat Boost 3. They both have gain knobs, for goI'd reason. In many cases, 2 pedals is better than one. Take the Timmy. Base dirt is a BB Preamp. Think clean amp, BB creating AC/DC level crunch. Step on the Timmy, which goes into the BB for leads. The combo make a better lead tone than either pedal can alone IMO. I didn't need a pedal company or magazine or the internet to tell me that. My ears did.
