Solution to combine Bass + Synth (keybass) into one output

[NicJimBass]

I did this for a few years. Since you don't need to use them simultaneously, you can run a A/B box just before the DI. Get the volume where you want it on your bass, then match it on the keyboard, using it's volume control. A little extra EQ from the DI pedal shouldn't negatively affect the keys' signal. Many simple A/B boxes can be found for less than $50.

Though this was not the original question, but it is worth to think about the need for effects after the BS2. I have mine plugged into one of the returns of an HX Effects, so muting and adding effects is easy while maintaining one mono output.

I don't think you need anything fancier than Electro Harmonix Switchblade Passive Channel Selector - Google Search
slap a di on the end and you're golden
all this is is three jacks and a switch. no need to over complicate (20 bucks is roughly what I'd pay for parts to diy it so it's a no brainer)

I have a switchblade I'm not using. if you pay for the flat rate envelope, I'll send it to ya

Apparently there can be a pop with the passive true bypass ones, I saw a kit for $20 that claims to have "pull-down" resistors that eliminate the pop. Are there any premade options that don't pop? And are the pops that noticeable, and or distracting?

I really appreciate the offer, I'll follow up with you shortly

 

[thetragichero]

if it's a totally passive circuit, I would assume there's no stray voltage to pull down?
I will test when I get home since I'm curious

Mine doesn’t pop. The whole band does iems, so if it did, I would hear about it.

 

[thetragichero]

as I expected, no pops (at high gain, no less)

I would imagine pulldown resistors in this situation would be a terrible idea (especially with a passive di)
at the bass you have a volume pot that is 250-500k between 'hot' and ground (when wide open). radial lists their input impedance as 130k on their passive di boxes (it's just where Google led me for example's sake). adding another say 1M between 'hot' and ground just further decreases the total resistance in parallel to ground, so the result is fewer highs and lower output (not drastic, but we've done extra work just to obtain worse results - that's bad process)

a bit of a digression, but I think this is the reasoning behind the real world results

I didn't look up info on active DIs

I used my Radial bassbone. For the electric on channel 2 and the upright or key bass on Channel 2 which has no variable EQ (Just flat, bass boost and mid-cut switch - I set it to flat). It has gain for each , you cannot play simultaneously and the switching is quick because it is also a pedal. There are instances, that I cannot lay down the electric and have to switch to the bass keys as fast as possible.

It is however more than $50 even used. If you can get a Radial JDI for 70. I would go with that. I will last longer than a cheap Behringer Mixer which could die after a couple of gigs (my experience) It also can take a speaker output paralleled as well. I am thinking of getting one myself.

I used a radial JDI to sum my signals when I ran keybass. I think the ProDI has the same function and you should be able to snag one for around $70. That extra $20 will buy you a product that will last you a lifetime

FOH doesn't have 2 (!) channels for you? Really?

Monitoring only allows him one, I asked

 

[Gigglingbuns]

Oh they definitely do, they have a Digico SD9, and we aren't we close to maxing out it's inputs, it's that there's one channel dedicated to Bass on the avioms that we use to monitor us, it's definitely much easier to balance the volume on my side, vs having the engineer do it. Another thing the way the stage is built, there are small boxes in the stage around where the DI outputs snake all the way to a wall-mounted box backstage. That leads to a rack of inputs, outputs, everything that connects to the mixer is pretty much there with the exception of microphone receivers which are next to the mixer. Anyways, there are a limited amount of inputs in the boxes of the stage.

Now that I remember they have some eq on my bass saved onto the session, I'll definitely have them remove that since the eq will really mess up the synth.

I've done gigs where I was lucky to get one.
