Recently acquired one of these and I've got to say, I am very impressed. It sounds very, very good and has a nice studio quality to it. Everything you feed in sounds better coming out. It has a real precise feel to it. By that I mean it plays faster and with more articulation. The EQ points are all very useful and not overly dramatic. It's one of those EQ's that sounds good at most every setting on the dial. I also appreciate having the low mid and high mid controls. The Low Mid EQ shift between 333hz and 473hz is very useful. It can really can serve as a hub for your board with the mute switch, dual channels, multiple loops, a blend of dry and looped effects, multiple DI outputs and more. It is not the smallest preamp out there making it not as pedalboard friendly as some but I've got it on an old Pedaltrain Jr just fine. It requires 12 volts and 500ma. My CIOKS DC7 easily powers it off one port. I'll gladly sacrifice size for all that the Trilobite offers. The Trilobite would make for a nice studio preamp too. I love the LED indicating signal gain - green for normal and red when clipping. No cab sims but plenty of flexibility with dual channels, multiple loops, dry/wet blend of the effects loop, headphones out and Aux in. Multiple DI outputs. I really like the dual channels. I've been using one as my primary always on and then setting the second with a little more bass, pushing the mids a little and a touch more volume. I kick that on when I want to pop out in the mix just a bit more. You can also use the dual channels separately for two different basses each with their own input. Nice. When switching between the two channels (A/B) the LED changes color to let you know what channel you are running. Real nice having the FX switch too and I love the mute switch which means I don't have to rely on a pedalboard tuner to mute my signal. The LED illuminates Red when the FX loop is active. It is a clean sounding preamp, but by no means is it sterile. Don't expect tube tone out of this one. But do expect a highly polished, studio quality tone. Every bass I've used it with sounds that much better. Bigger, more punchy, better. There is a blue LED that illuminates when the preamp is active. Trickfish has release the Minnow, the little brother to the Trilobite. The Minnow has the same circuit as the Trilobite, but only one channel and less features. The Minnow is great too, but the Trilobite offers so much more. Both the Minnow and Trilobite have a nice quality feel to them. The Trilobite is much lighter than I expected which is great since I have it mounted with velcro on my pedalboard. I'm sure I'll have more to say as I use it more but initial impressions are more than good. The Trickfish Trilobite is really good. It's like the perfect balance between a device for knob twisters/tone tweakers and those wanting something that is quick to adjust and just flat out sounds awesome. Anybody else using one?
