If it's ready made, this will get me down! (5)
I believe the answer is:
reach
'get me down' is the definition.
'reach' can be an answer for 'get' (reaching is a kind of getting). I'm not sure about the 'me down' bit.
'if it's ready made this' is the wordplay.
I cannot quite see how this works, but
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is found within the answer.
The remaining letters 'rach' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'will' is the link.
Can you help me to learn more?
(Other definitions for reach that I've seen before include "Stretch of river: achieve" , "Limits within which something can be effective" , "Be received" , "Open stretch of water" , "Attain - continuous extent of water" .)
