Two preamps into single output

[JPJ]

So my little pedal board is great and because I regularly double on electric bass, acoustic bass, upright, EUB, and all combinations in between I have the EBS Stanley Clarke at the heart, and a SushiboxFX Finally valve DI at the end. For electric gigs, I’m thinking of adding my Sansamp back onto my board, but it seems daft to daisy chain two preamps when one will only ever get used with electric bass or to run the Sansamp in the loop of the Stanley Clarke (which is what I used to do). 

Is there any reason why I can’t connect the two preamps to the Finally DI with a simple Y cable. I realise I’ll have to be careful balancing the output volumes of the two preamps, but other than this, is there a technical reason why this will not work?

Better might be to use a Boss LS-2 before it so that you can trim the volumes of both chains going into the preamp and use the footswitch to select between them.

I did think of this, but space is of a premium on my little board hence the original enquiry.

I would suggest an

 

An ABY*, that is. Two signals in, one out. Mechanical switch. Some have LEDs, too. I think prices start from £20 or so.

 

*An ABY box, or an abyssinian cat

Looks like one of the small ABY boxes may be the way to go then. I see Mooer do a nice little unit.

 

That said, I’d be careful there @itu it looks like you are close to letting the cat out of the bag (………..I’ll get my coat) 😂

I have a micro mixer made by Max of SFXSound ( @Silent Fly ) that blends signals, but I’ve not seen Max around these parts for a while. Absolutely brilliant little box that even has an LED to light up your board on dark stages too!
