help with splitting signal

I am currently running all my effects through the line straight into my amp but I am not getting the desired result.
I want to be able to split the signal so I can run my main amp constantly with the clean tone and run all the effects through a seperate guitar combo, controlling it by a foot swtich to kick it on/off wherever needed and combine the two signals front of house to blend the sounds together.
Has anyone got any advice or tips for gear to acheive this? and any pitfalls I may come across

cheers

put a buffered pedal with stereo outputs up front, then use an A-B box in-line with the chain going into the guitar amp so you can turn it off and on.
 
This may not be exactly the thing to do the trick, but Boss has a pedal, maybe the "LS-2", which will let you control one or two loops (signal chains, not a long echo). The controls allow you to set the levels of each loop and then you can access loop A, B, or both at the plop of a foot.

Pretty sure that this could work for activating the effects and guitar amp on demand while playing. One of the bass magazines did a run down on this pedal a few years back and it seemed like a supremely useful gizmo.
 
the boss line selector, sure.

it's buffered, meaning it takes any signal and makes it active, so that it can then be split without loss.
 
my "ghetto" way was to just use a mixer on stage, bass to line in, main out 1 goto clean amp main line 2 goto effect amp, then put a volume pedal before the mixer to control all, and then the effect amp another volume pedal ( I usually kept clean on at all times) Never used it on stage seeing i dont got 2 good amps ( got 1 good one and one that is crapping out) but it did work.
 
Two questions: Does your amp have an effects loop? Do you have a pedal tuner/ mute pedal / AB box? If so, just hook up the effect signal chain to the effect out, and put the mute as the last thing in the chain to keep noise from pedals that are on. The only problem would be if it is too strong of a signal, in which case you might need to use a volume pedal or else bring the overall gain down on the first pedal or two

that's good.

you use your bass amp's preamp section to drive both its own power amp and (through some pedals) another amp.
