Korg ToneWorks AX1500G - What you hear is not what you get - Help Please!!!!!

I've been using Cakewalk Sonar 6 very happily for a number of years, and as it does all that I want, I've never felt compelled to upgrade to any of the newer versions. I find that with a liitle bit of tweeking here and there I'm fairly happy.

However, I am struggling of late to have it capture the sound accurately from my Korg Toneworks AX1500G  which has my yamaha sg1500 electric guitar  plugged in. To be precise, it always sounds less meaty ( best description I can come up with) than say it sounds if I just plug my headphones straight into the headphone outlet on the pedal.

I have tried various tweeks on the pedal, in cakewalk, the Edirol FA-66 audio capture box, but it just seems to loose tone and  between the korg and the completed track. What you hear at the pedal is not what you hear in cakewalk. 

My projects are typically using a sample rate of 4800 and a bit depth of 24 bit. 
Laptop is a Dell Precision M4400, Intel 2 Core Extreme, 4 GB Ram, Windows XP Service PAck 3, Edirol FA-66.

Never have any latency issues, glitches or drop-outs, my laptop is 'tuned' and configured to work at its maximum for DAW work (courtesy of 'Sonar 6 Power, The Comprehensive Guide' by Scott Garrigus ).

I have searched the cakewalk forums and other forums but cannot find anything like this described elsewhere
Any help and / or advice will be most gratefully received.

That's a stereo device. Are you recording from a stereo out? If so, try recording mono and see if the tone changes. Or split the stereo track into two mono tracks and listen to them independently. Are they fuller-sounding by themselves than when combined?

I have an external synth that sounds crappy when I record the Rhodes patch in stereo, even though it sounds great with headphones plugged directly into the synth. It sounds thin because of comb filtering, as if the two sides of the stereo output are slightly out of phase with one another. The giveaway is that the patch delivers fuller tone in mono.

If there are phase issues between channels on your Korg, you could be experiencing a similar phenomenon. See if it only happens when you use the stereo chorus or other stereo effect. 

Thanks for your advice guys. I will look at this tonight and let you know the outcome.

Best Wishes!!

The majority of us see no need to go beond 24/ 48. After all it's all going to end up as 16/44.1 or worse in the end. There are issues when you try crunching that many numbers with all but the most hardy of computers and interfaces. Nobody we know can hear the differance.
