Unusual blend requirements - looking for suggestions

danowens

Hi all,

Twice recently I've needed a blend solution and can't find anything to suit so maybe I'll think of building a kit or my first breadboard. The situations are:
1. I want to blend a slap pickup with the output from my NS EUB. I'd need two channels, one for the 18v EUB output and one for the passive slap pickup (ideally with a ridiculous high pass filter). Each channel should also have either a volume or blend. 

2. I want to put a thin jazz pickup on a Yamaha Silent guitar (Kent Armstrong or maybe Vintage Vibe). Again the instrument has an active output that I'd like to blend with the passive pickup. This wouldn't need a high pass but it would need volume/blend. 

Is there anything that you guys can suggest? It needs to be small as I'd like to mount it to the instrument. 

Thanks!
