I just received my tx version today. I had to play with it for a while before I started to get something I liked. I discovered that the input level is key to getting a good sound. Once I started to get a feel for the controls, I was really pleased. The controls are very effective. Small changes are very noticeable. The large knobs really help you dial in a just-right sound. This much range with small knobs would suck live. The sound is definitely not transparent, but does allow the character of each instrument to come through. It adds a sparkle and liveliness that reminds me of what you get out of a very good pre-amp. At first I thought the sound was dull, but once I started playing with knobs I was able to get really great full range tone. I was monitoring through a cafe walter headphone amp and a pair of ultrasone hfi-780s. I tried it with several basses. As I expected, the best settings for each bass varied widely. With the Music Man Stingray 4 Classic, an already very compressed sounding bass, I was able to create a great bouncy note sound. On the Fender MIA P5 I dialed in a tight percussive attack. You get the idea. Compared to my Empress, it has way more attitude. The Empress is a very good compressor. I just never liked a lot of compression on it. It is not the fault of the comp. I just never liked heavy compression on bass. With the Cali76, I found that with the right setting I could easily turn the ratio up to 12:1 and still sound like a real bass player!! The secret, as I said before, is the input knob. I also ran it as a 20:1 limiter with my Fender 60th anniversary P loaded with Nordstrands. It sounds excellent in this mode too. I think one of the secrets of this comp is the very fast responding circuit. I don't know if this makes sense, but it just seems to respond in a very immediate and natural way. This makes the comp like another instrument. I found I could make the comp respond in very musical ways to my playing style. I have not tried the DI yet. I will probably check that out over the weekend. If that turns out to be as good as I expect, I would definitely say this pedal is a bargain. Yup, you heard me. It is cheap. A top studio comp and DI for under $500 is a very good deal. Finally, the construction is the best I have seen anywhere in a stomp box. It will last for many years with proper care; I am sure of it. It has a very solid, purposeful look with a beautiful polished metal case, handsome graphics, and nice chunky retro knobs. I think Simon put a lot of thought into the appearance. Even the mini toggles in the back feel good. They are slightly recessed to allow easy access without accidental switching or damage. I have no doubt that these units will be very highly prized in a few years. A good investment and a real keeper.
