I have a small band in which I play 2 different Ukuleles with externally mounted Dimario piezo-electric pickups, and an archtop acoustic with a suspended humbucker pickup. Each of the ukes is plugged into it’s own 7 band EQ pedal. The guitar is plugged in to an overdrive pedal then it’s own 7 band EQ. I then plug each of the EQs in to two AB switches daisy chained together that feed a single DI box that feeds one channel on the mixer (Carvin 880). I attached a diagram1. Once I set the EQ and volume on each instrument I can press the proper switch on the AB switches and pick up the corresponding instrument and play and it sounds great. The drawback is that is an awful lot of stuff on the floor. Now I have just added a lap steel to the act, it has a single coil pickup. I was thinking about buying a small 4 channel mixer and mounting it on a stand where I can just control the instrument I am using with the channel output or a mute switch (some small mixers have them). But I have gotten confused about the role of the DI box. In my current configuration I switch to the DI. Do I really need a DI for each channel if I use a mixer? Can I just plug the instruments into the line inputs on the small mixer. See Diagram2 I have also found a 4 channel DI/mixer to buy but it doesn't have any EQs So I would have to keep the EQ Pedals. Kind of defeats the purpose of using a small mixer. Does anyone have some advice?
