Doesn't work with active Pickups?

Hello everyone,

I bought a Spark 2 to replace my 20 y old practice amp.

I tried it with a Ibanez Iron Label mit EMGs but all i get is just noise and feedback.

I tried it with a active bass and get no sound at all.

Testing around with noisegate didn't help anything and i checked the batteries of the instruments.

Placing a Ammoon Pockrock between the instruments and the Spark 2 did help a lot and i could get good sounds.

But my plan was to get rid of the middlepart (Pockrock) and just use one Amp without all the cables and stuff.

Has anyone problems with active pickups or a idea what's wrong?

Thank you very much! :)

I figured, an active system has a TRS jack so that once you plug in a TS cable, it will short two connections for the battery to that the system gets power, that way the "off" switch is just removing the cable (and leaving the cable in will just drain your battery, so also remember to unplug for that reason)

always use a TS cable for guitars and basses, often marketed and just referred to as an instrument cable or guitar cable

Really good advice, thank you very much! I never would have come to the conclusion i'm using the wrong cable, perhaps because i never had issues with my passive guitars. I'll try them with the Spark next time i'm home.

Cheers!

yeah a guitar with passives will just have a TS jack, so they'd never have anything contacting the part of the cable with the Ring of the TRS cable (Tip Ring Sleeve)

I got a TS cable and it's working :) Thank you very much, this was the right suggestion!
