Hipshot D-Tuner on Cirrus???

I assume the GB7 should be the one that would fit.
Anyone know for sure?

 

Those are aftermarket.

Peavey calls the ones on the Cirrus basses Gotoh "Mini" tuners. They haves the small, round, enclosed backs/gears. I'm almost positive they're the GB7s.

 

These are the standard tuners on a Cirrus:

 

AHHHHH. That makes sense. I've got the Minis.

 

UPDATE:
For Cirrus owners with the standard Gotoh Mini tuners:

If you are looking to put on a Bass Xtender, the GB7 is indeed the correct Hipshot extender, however, you will need to request the old style GB7 (the current version has a different shape key). Oddly, they still show the old style on their (Hipshot's) website.

Also, the GB7 has a string post that is only 1 1/8" long. This will be too short on a Cirrus with a headstock thickness of 5/8".
To make the post the same length as your other tuners you will have to have them make you one with a 1 1/4" long post.

Jason at Hipshot did this for me and it works perfectly.

 

I got it through a third party dealer who deals with Hipshot directly. I won the New, Gold GB7 for $70 from eBay. After we found the problem (putting it on my B string on a Cirrus 6, BTW) of the post being too short, he said Jason at hipshot would make me one custom for an additional $10. He then waived the $10, but I sent it anyway for his troubles.

 

Yeah.
Weird side note: Jason said he had sold these to Cirrus owners before and never encountered the short string post problem. I find it hard to believe no one else had this problem or just put it on their bass and lived with it.

I had a Millennium for awhile and that came with one already installed. No problem with string post length, but I don't know if the headstock is the same thickness as a Cirrus.

Maybe he was just confusing other Peavey basses in general.
Could it be I'm the very first one to put this exact tuner on a Cirrus???........maybe not.
