Input impedance for active piezo (Ibanez SRH500)

[Jack]

Hi all, 

 

I'm trying to get my hands on an Ibanez SRH500 that has a piezo pickup in the bridge, then some sort of preamp. Specifically it is what Ibanez call their AeroSilk system. With it being active, do I still need to worry about the input impedance of what it's plugged in to? The input of my wireless is only 900kohm.

If the piezo is already buffered, there's no need for an extra preamp.

It functions entirely as any 'normal' bass...

[Jack]

Thanks both. I don't actually have the bass in hand so can't test but nice to know it's doesn't need the really high input impedance of a piezo-specialist preamp. 

 

I have plenty of great gear that would work regardless, all the way up to the 10Mohm that my Countryman DI is, but I'd like to use my existing wireless > helix rig.

What preamp does it have?

 

Will most likely be a variation on the old in house Cort preamp they put in their older piezo equipped basses which works really well, they used to slap a Fishman license on it.

They call it AeroSilk.

That looks quite interesting, seems like the piezo has its own little buffer preamp on a separate board before hitting the preamp, looks like it has individual trim pots for each saddle too.

 

Means you could swap the main preamp out easily if needed.

It's not a high output. Can't give you numbers, just anecdotal evidence. But when I switch between basses it's one on which I have to increase the gain.
