That's quite an endorsement! For milder dirt, I've been using a Tech 21 VT Bass since 2011. I have a Source Audio Aftershock that is capable of all sorts of dirt. I'm thinking of swapping the 4OTF for the VT and seeing how that goes. I definitely didn't need the pedal, but I couldn't resist. We're living in an amazing time for gear!The 4 On The Floor replaced three of my pedals. A tech 21 and two MXRs.
