This bass is gorgeous. It sounds great for practice. I have had feedback issues when plugged into an amp, but have learned to move to certain areas away from my amp to keep this from happening. The pre-amp has Aphex circuitry which when used with the EQ provides some awesome sound combinations. I always get compliments for the looks of this bass. It is my go to practice bass. I leave it out near my bed so I never have an excuse not to practice since I don't have to plug it in.
The first time I saw this bass played by a professional was back in the early 2000's when I saw acoustic Strawbs. Chas Cronk was playing one. I just learned from Elliot Dean Rubinson that Dean no longer uses the Aphex circuitry in their newer issues of this bass (and entire line of acoustic guitars and acoustic basses) because Aphex was sold.
I wasn't too crazy about the phosphor bronze round wounds that came with this bass (not sure what brand they were) so I bought a set of D'Addario half rounds. These strings have some squeak, but no where near as much as the phosphor bronze stings. However, even though they are louder than flat wounds, they are definitely quieter than the phosphor bronze strings that came with it. To each his own I guess? I am looking for brighter half round strings to get a brighter tone closer to the original strings, but with less squeak. Why am I doing this? So I can be heard when playing with acoustic guitar players and not need my amp to be heard.
