Does anyone know if you can connect Bluetooth headphones before I go buy a pair 

I was using the usb connection to record on Audacity.  The guitar I was using was a Fender Strat with noiseless pups.  I found that the signal stregth was really low and the only way I could get a decent recorded signal was to turn up the master volume to an unbearable level and was close to getting a stern talking to from my better half.  I then tried the same process but used some headphones and this sorted the level issue so it recorded a strong signal.  There was still a bit of crackle on the recording but much improved from the last firmware release.  

I then recorded some acoustic guitar without headphones.  This was a martin DRs1 with a stock fishman pup.  Signal strength was really good and the quality was great.  No hum or hiss or crackle.

Great to hear others experiences.

Hi, just bought a Code 25, I'm happy with the unit to a degree, but I have one niggling dought that I may have a faulty unit, it seems to be more noticable on certain guitars, when playing my Tokai strat, on the Bluesbreaker presets( 41,42,43), I get a horrible harch distortion ( as though its overloading the preamp, but ony around the 5 and 7th fret of the G and B strings) this also occours with headphones, if I back off the volume on the guitar it does reduce the distortion. Has anyone else noticed this?
