Received this pedal today and played with it for around 30 minutes, so those are my first impressions. First of all, this pedal is totally different from the other filters that I played before: Q-tron, MXR Auto-Q, Moog. It doesnt have that much of the effect, its more like blended with the dry sound. I would say on some settings you may not notice it in the mix until the pedal is turned off. So for someone who likes Bootsy, this pedal could be a disappointment, BUT it is cool in its own way. I would say this pedal could be a secret weapon, it makes sound bigger, sort of like when you are trying to repeat some bass line from the record, but it doesnt sound exactly the same because of the sound its own, though you transcribed every note. I have some pedals that I like to play with on my own, but I can hardly use them together with the band, this pedal, I can see where I will use it from the start. TF Analogue Filter in my opinion is good for acid jazz bass lines, where you dont need to play many notes, but you want to have them fundamental and groovy. So overall I think this pedal is a good investment and is good to have, though if you looking for something that sounds close to Mu-tron better check something else. P.S. The Real Funk comes when you switch it together with MXR Auto Q.
