I am getting into the world of "doubling" between electric and acoustic upright. I have been researching options and there seems to be so many options available. Right now, I use a REDDI direct into the house with Shure in ear monitors (SE425 dual drivers) and I love the sound. My Electric Bass is a Marcus Miller modified with Aguilar Electronics. I am probably going to get a Realist pickup because I am more interested in a darker sound for the upright. When I played upright in the past, I used an Azola Bug Bass EUB and just plugged it straight into an SWR amp with no preamp. Has anyone ran a Realist straight into a REDDI? Is a preamp required? I want to incorporate the REDDI into my setup somehow because it sounds so great but maybe with the UB it doesn't.
