I need a 2-in, 1-out mixer in pedal form to add to my pedalboard. In my hiphop band I'm adding occasional keys/synth duties to my normal bass obligations. I'd like to route the keyboard to the tail end of my pedalboard, right before my Radial JDI. Ideally I'd be monitoring both bass and keys out of my bass rig (GK MB800 into a nEarful 15/6/1) I see a couple of options, and am curious how everyone else would do it. I could add an sfx microMix right before the JDI. That would allow the bass to go into input 1, my keyboard to go into input 2, and the output to go into the JDI input. Easy setup, small footprint, but kind of expensive being in the US (north of $200 US after the exchange, plus shipping costs). I could replace the JDI with Radial's Duplex unit. That would give me an independent DI for each instrument, would allow for a simple setup, but would cause problems with trying to monitor both bass and keys out of the same amplifier. A small 2-4 channel mixer (Mackie, A&H, etc.) could work, but this is the option I like the least. I prefer it to be something that could live on my pedalboard rather than something that would go on my amp, require an additional power supply, etc. I'm not 100% opposed to the idea if it's really the best way to go, but it's pretty low on the list, if not at the bottom. I could just stick a 1/4" Y-Cable in the mix, but my assumption is that there would be some impedance differences (keyboard output, versus a bass running through a series of pedals). This is compounded by the fact that I'm frequently using both the bass and the keys at the same time. So, what would you all do? I'm leaning towards the sfx unit, but would love the same concept in a less expensive version. Wishful thinking perhaps. Thanks!
