Takamine CT4BII

As you would expect with anything Takamine, this product is quality in every way. First off, the preamp has a solid, well-built quality feel with all of the components well made. The sliders are smooth to operate and give the impression that they would remain solid and functional after loads of gigs.
Fitting the preamp is very easy, with only two holding clips to release. The wiring contacts are super easy to fit and the whole process should only take a couple of minutes.
In operation, the preamp does exactly what it is supposed to do! The EQ section is sheer class and has a neat subtle effect on the guitar's sound. The tuner is acceptable and accurate enough for live performance. However, if you want more accuracy when setting-up the guitar you might want to use a dedicated tuner.
The one downside to this preamp is the battery compartment. It is unnecessarily difficult to take the compartment out to change the battery, not impossible but not easy!
