Bypassing Preamp on Ashdown ABM 600

[Pirellithecat]

Probably an obvious answer to this, but I've tried and failed so far!  
I want to try my Laney Digbeth pre-amp pedal direct into the power amp stage of the Ashdown.    So the circuit would go Bass>Digbeth>Ashdown Power Stage.  I can get the Digbeth to work via the Send Return Loop, but this means the bass is plugged into the Ashdown and passes through the Ashdown Pre amp before it arrives at the Digbeth.  
Anyone know how to make this happen? 
Thanks

plug your bass directly into the Laney, then go from the Laney to the RETURN of your Ashdown - that should bypass the Ashdown preamp entirely.

Yep 👍

You'll need to put a cable or something in the input of your ABM. Ashdown amps usually have a switching jack for the input that mutes the output. Something like a 3.5mm to 1/4” headphone adapter would do the job.

Thanks all - sorry about the duplicate posts!!  
I'll go and try the headphone adapter later - I'm optimistic.! 
Just taking a feed to the "Return"  doesn't work  - you can put the Pre in the FX Loop but can't just use the return.   Same for the Line input.  ...... Fingers crossed.

Yup, this, 100%.  I used to use a mini-jack adapter.

Great!  That's the answer!  Works.   Having said that I think that the Ashdown preamp rather compliments the Ashdown power amp ...... putting the Digbeth in as a replacement, isn't as pleasant as using it at the front end, even with the Ashdown Pre flat or the EQ turned off.   But many thanks!
