If you read my previous post then you read that I planned on purchasing the Digitech bass squeeze pedal in the near future. But "What about the other 3 pedals in the series?" There is a chorus, distortion, and Synth/auto wah.
First the chorus....If you're not a fan of chorus on bass....GET THIS PEDAL and you soon will be. It has to be the best chorus I've heard, EVER. Even if you run a multi effect unit there is nothing on there that will come close to this chorus.

Second, the distortion...This is a pretty basic "bass distortion" pedal, with simple tone and blend controls. If you already have a distortion pedal you like, I wouldn't replace that with this one, but it would be a great backup to any distortion you have, or if you don't have a dis/overdrive pedal, this would be a great one to get, it's very versatile and can get you the subtle SVT grind to an over the top crazy fuzz sound, while still maintaining the bottom end of your bass tone. Great pedal!!!!

Last the Synth/Wah...This pedal is crazy...and then it gets crazier. I haven't really messed around with this thing too much, and to get a sound other than the "bass yeah" it will take a lot of work/time to dial something in. But even for the one trick, it can add some craziness to any song...especially the boring ones...LOL.

So, to reiterate the review of some old pedals...
Bass chorus (GET IT!!!!), Bass driver (only if you are looking for a new one or don't have one) Synth/wah (if you want your bass to say "yeah" or if you want some crazy octave, synth, or wah effects)
