Help With Active Basses

This month I've gotten two Active Basses, (One new and one from a local Pawn Shop.) and I've been having this problem where the Basses barely work when I plug them into my main Amp. To make things weirder, the Basses work perfectly fine with my CRATE Speaker (8in Combo-Amp with no effects), I know these Basses work because of the before mentioned CRATE and the fact that my one Bass has a Push/Pull Active/Passive Knob and it will work when I make it Passive.

I was thinking the problem might be in my setup but I'm not sure where, so I'd like to ask for some help with this. Here's a list of my current equipment:

Basses: Schecter Stiletto Stage-4 (New), Ibanez BTB (Pawn Shop).

Amp: Carvin V3 Tube Amp (3-Channel, Running Both Amps, Set To 4 Ohm).

Cabinets: Peavey 1x15 Speaker, Fender 1x18 P.A. Speaker (Exact Models Unknown, both 4 Ohm).

Effects: EHX Green Russian Overdrive, EHX Small Clone Chorus, Ibanez Weeping Demon Wah-Wah (Powered By Plugin Chain).

I'm not sure where the problem here would be, I suspect around the Effects area, however I don't know.

did you plug straight into the amp? bass-> cable-> amp.

To show how much I.Q. I have in real life... no.

I'll try that later tonight, I've thought of it I just haven't gotten around to it yet.

I worked as a recording engineer for a decade. Remove variables quickly. Target the problem area through logic. Identify the issue. Get back on the clock and get rent money.

Edit: I still work as a tech and custom gear designer/builder as a sideline. Eliminating variables is key.

Also active pickups have a preamp that sends a low impedance signal to a high impedance (1mohm nominal impedance) amp input sooooo... but I expect a bad jumper cable that operates more consistently with high impedance and low voltage passive pickups. Although that's odd.

To show how much I.Q. I have in real life... no.

And for posterity? Yes. You're dumber than a box of hammers. The route to the solution is obviously to remove all variables and reintroduce them 1 at a time. I'm not trying to be mean but you didn't do any thinking prior to posting for help.

Minus 10 masterclass soldering iron points... your issue is easily solved without a masters degree

It's fine, I acknowledge that I'm dumb, I joke about it a lot...

Should get to the Amp>Cable>Bass thing much sooner, but I'm just that lazy.

okay, I was drinking and I think that I came off meaner than I meant too, it was meant more in jest, hence the dumber than a box of hammers line from O Brother Where Art Thou... but it should take 5 seconds to plug straight in and see if the signal gets to the amp from the bass directly... make sure to test both the cable going TO the pedals and the one coming FROM the pedals. Eliminate those variables. Also try another lead, like your backup cable for shows? make sure that works. Make sure to jiggle 'em around a lot to see if they're intermittent. Then change speaker cables... then reintroduce the pedal chain a pedal at a time with brand new jumper cables if you can... if you stillc an't locate the problem take a sledgehammer and start smashing stuff.
