| I used to have a GT-6B and only used it bass>GT-6B>Amp input.
Sounds like your amp has a parallel effects loop, so it's not much good for thre GT-6B.
Some people use the multi effects like Bass>Effects>amp effects return, bypassing the amp's preamp section and using the multi effects preamp instead.
I also found the GT-6B preamps not so good, and i traded up to a GT-10B, way better preamps and loads better effects (except the synth has less parameters).
The GT-10B has a external loop (like an effects loop in itself) which can be used to setup in four cable method (4CM) where the amp's preamp section becomes selectable and movable within the effects chain.
For the GT-6B, if it sounds good running as you have it before, and you are happy, then i would leave it as is.
The effects loop on your amp being parallel type, mixes dry and wet signals, and in this case causes strange phase cancelling, making it sound like there is a hole in the tone.
