Promises, promises ... "we'll fix it soon";  " bluetooth issues will be addressed in future firmware updates";  " USB recording issues will be looked into"; AND, a 2-way footswitch will be available for Code 25/50 users when Code 100 is released.  Am I alone in my disappointment for Marshall's seemingly apathetic (non) responses to purchasers of their "not ready for prime time" digital products?!?!?!   I really wanted a Marshall Amp after 45 years as a Fender user.  My mistake.  I should have known better.  Useless, unsupported, glitched, buggy, unreliable, etc., etc., etc.    What say you Marshall in an attempt to save any reputation you thought you had?!?!?!?

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.
