aux input on an amp head

[Geek99]

If I have an amp head with send/return plus one input - is there any way I can use a drum machine?
My practice amp has aux input and larger amps I want to upgrade to don't.
I do not need a gig solution, just home use
Thanks

Just get a cheap 2-input (or more) line mixer - you can use the amp send as one input ,the drum machine as another - route the output back into the amp return

(Or get a cheap mixer with preamps and just mix before the input...)

i used my bddi on the return socket and fed my bass into it

in effect i left the input sockets on the combo free for any other inputs

why...well i didnt want my bddi to go through the preamp...so the drum thingy has to have some welly to do the job if oyu are using the return
blending of course will help

So I could connect a device to the return only and ignore the send? Such as an audio in, or a drum machine? It wouldn't generate lots of noise or somesuch?
