 Hi, I just purchased a brand new Larrivee LV-03RE.  It is equiped with the A5 B-Band.  I am quite pleased with the sound of the guitar unplugged, however when I plug into either my acoustic amplifier or my Boss multitrack I get a conspicious hissing noise. It is audible as  I approach the half way levels of the Tre and Pre.  If I exceed the half way points the hissing becomes glaringly conspicious. 
 
I double checked my equipment by plugging my Taylor 310CE cutaway (fishman prefix plus) and in both my amp and multitrack recorder and the hissing was totally absent, not even the slightest degree. 

Does this occur because of the performance limitations with the UST and/ or preamp?  Can the A5 preamp be made to work with a receiving apparatus other than the UST?

Do you use a DI box in the signal chain? I had the same problem and solved with a simple Behringer DI box which eliminated the hiss.

Timely advice for me also. My partner's plug-in uke has been hissing. I bought a DI box (passive) years ago at the advice of a guitar salesman, and have never used it - I'll try it on his uke tomorrow.

What exactly does a DI box do, anyway?

I might not explain this properly, but a DI box takes a low level signal like that of a passive pickup and brings it up to line level. You can then plug directly in (DI) to a mixer line input or an amplifier with a much better signal to noise ratio (SNR) and hence no hiss.

DI Box is a must for all serious acoustic player and recording. it works like a filter and stableliser.
