Double Bass Understanding send/return loop

Trying to get a doubling rig going. Double bass is running through a DTAR Solstice preamp. It does a good job of impedance matching with the Fullcircle pickup. I tried running the output from the preamp to the FX Return on my bass amp (a GK 1001RB). It sounds great. But when I plug my electric bass into the 1001RB, I get no sound from the EB when the preamp is plugged into the FX Return. If I unplug the preamp from the FX return, all returns to normal and the EB works.

So does anyone know what the FX return is doing to the Channel 1 (EB input)? :confused:

On my AI amps/heads, you can use the effects return and the regular input at the same time, and this lets you plug 4 different things into your 2-channel head or 2 into a 1-channel - IOW, not all effects loops work the same.

Outside of the EA Doubler, Acoustic Image, or the little MARKACOUSTIC AH 250, and Genz Benz Shenandoah. What other choices are out there. I hesitated to include a Walter Woods because they are way out of most players reach.

If your volume needs aren't real high, another smaller/cheaper option you might find on the used market: Dean Markley KAC-60. I got an old one given to me as a thanks for doing a pickup wiring job for a fiddler I know.
It's a single 12" (or maybe even 10" - haven't looked at it that closely) with two channels, with 1/4" and xlr ins on each one.
Mine has some power section issues at the moment, otherwise I'd gig with it in a second.
The Eden Nemesis combo (older silver-face model) I have has a second aux channel also, which if one's using an external preamp would work just fine. I think the newer ones still have this also...
There are also quite a few smaller amps that have a CD in....I imagine with the proper cable/adapter you'd be able to use that as the DB input (with the external pre).

I didn't mention that I had a two channel Walter Woods MI-400-8 and a dual channel Walter Woods Ultra.
So, I have two amps with two channels.

Thanks for coming up with something I hadn't seen though.

Sorry, may be a little off-topic, but I’ve also got the MarkAcousic AH 250 in the AC101h combo . I need a bass amp with a vocal input and this seems to be the only one . The manual says it’s good for Upright but I can’t seem to get a dry sound . There’s a slight flange or chorus with all the effects off.
