This is a Bluesbreaker (left) and Tube Screamer (right) style combo pedal which manages to sound like neither of the two. Let me elaborate on that statement - while it has the sound signature of BB and TS pedals, it has its own unique identity and probably wouldn't be immediately identified as either a BB or TS.
Can it sound like a BB or TS? Sure, if tweaked right. You can get some very killer tons from each side and also stack them together for a nice high gain sound. You also have clipping and bass DIP switches inside of the pedal for more tonal possibilities.
The pedal is sturdily built, knobs turn smoothly without feeling cheap or brittle and the switches are footswitches are solid.
The LEDs do a great job and telling you what's on and what isn't without blinding you if you look down at the pedalboard.
If I had to criticize the pedal, I would probably give it flack only for the markers on the knobs, as they aren't very easy to see, especially if you're in a dark room or have other things with bright lights on your pedalboard.
So, who's this for?
I wouldn't buy this if I wanted a replica of a BB or TS that is as high fidelity as possible - the originals are there and there are also other pedals that do this better. I would (and did) buy this if I wanted a very versatile pedal that gives you a lot of different and unique tones. This is probably not coming off of my pedalboard anytime soon.
