Some of the best preamps ever made! Any jazz bass I own will have these. Sounds amazing in my Lakland JO5.

I got one of these for my Japanese 62-style Jazz bass, it preserves the original pickup sound very well but gives more tone shaping which I need. Really nice product, highly recommend

....Best preamps for sure!!! And a real bass player!

What a beast of a bass player! Great demo, this is how all demos should be like. All he missed was more of a Rock-ish/pick style kind of vibe but understandable.

very nicely presented. i am sold!

Saw you, John, at the 2016 London Bass Guitar Show. Thanks for your patient demonstration of the J-Retro. I will definitely be getting one for my Geddy Lee Jazz bass when I have the budget. Dave (winner of the 2016 bassface competition)

Thanks for the comparison . Very clear 👍

Thank you for confirming that passive jazz basses sound freaking amazing.

Great demo, great bassist.

what a great preamp I have one in my darryl jones 5 and my road worn jazz bass..Im addicted!!

Hello Yesterday, i went to Hot Wire Basses Bert Gerecht, he inserted to me J Retro Elektronic in my Squier 5 Strings Jazzbass. Very very good Sound much better than before. You will be inspired.

I have one of these... fantastic preamp.

absolute bass design

very impressed with reggae sound! Although for other styles of music i'd rather stick with passive, as i think it sits in the mix better.

Outstanding, SOLD!!

i like it passive

Gorgeous !!!

Good to know. Thanks!

Hallo Hallo Hab mir gestern von Bert Gerecht ( Hot Wire Basses ) eine Retro-Elektronik einbauen lassen. Leute macht das und Ihr werdet mit dem Squier Euer blaues Wunder erleben. Unglaublich wie das Teil fett Klingt. Kann ich nur empfehlen.

Thank you friend! In late July I contact!

Nice Demo...

U/j retro NOT filter based. But East realized a filter based / pre for the "acg basses" company . They sell those kind of filters .I have one . Personal view of those = Tricky pony ,great when you have time to settle with controls (i.e HOME and studio) . But Live/stage if you touch the controls on the fly---- you can easily make a MESS ,both to you and the Mixer-SoundGuy unless you know the controls VERY WELL ,as they change the sound quite dramatically with slightly movements.

I own 3 of Your products (U-retro , ,acg and a "sp2 "wood&tronics) ,and love them all .Used on my video demos too (wood &tronics basses and a 5ver retrofitted). I would switch sp2 for U-retro maybe ,for mid semi- parametric control and ultra bright setting i miss (mids for "adapt" on recording stuff,and ultra high which helpswen strings start to "die). Also i think sp2 and U-retro "sound" different somehow ,but cannot "bet" about ,i did'nt try on the same bass.

sweet!!

i have j retro deluxe, retro rules!!!!!

Good day. Thank you for this awesome and informative video. What pick ups r installed on this bass please.

Is there an internal gain control for adjusting the active volume to set it to be equivalent to the passive volume?

John can you get this preamp in a box. I'm not really into the onboard preamp anymore, however I do like it's transparency.

"Now I'm going to slam the front end with a Darkglass B7K and play doom metal with a pick." Oh - no, wait...

i own both already in different basses (noticed answer now thanks) . For the pre-shape Built-in of U-retro !! = there is a way (also in private Pm if prefer) , i could recreate it somehow on sp2 internally , or with the help of an external eq ?. So i could figure out how U-retro would sound in my bass that has sp2 . (but i would need to know what to cut/boost). I miss active blend nby the way (passive is not-existent actually ,as a blend )

yeah, but at least I can use the bridge pickup by itself for that jaco tone. I have one more question if you don't mind; how long does the battery last? Is it something you need to change every 6 months or is it something that would happen, say weekly? (I've never owned an active bass)

Hello John East, who would you guys do a review of this retro 01 in J with Fender Jazz Bass pickups with 60s custol shop ... I am awaiting ..

What pickup are you using here?

does it allow you to use one pickup at the time or blend the two like on a regular jazz bass?

are the East pre's filter based? If the J-Retro and P-Retro or U-Retro are not filters then does John East make a filter based pre? Thanks

This preamp looks good on a Fender Squier Vintage Modified V chords with funding duncan designed? You send to Brazil?

@JohnEeRetro is too much if my Jazz Bass is active then I will put J-Retro? it will become 18V.. what do you prefer? active pickups of passive pickups + the J-Retro.. Thanks for entertaining my questions :)))

can this be installed in Jazz bass V? Great Products by the way :))))

Hello John! I'll be traveling to York (UK) in July / August 2013. How can I buy the J-Retro 01 with you? I'm from Rio de Janeiro, Brazil. (google translation)

Best by far, shame he thinks the World is right handed.

can you still blend the pickups in passive mode?

price?

That accent sounds like a Trinidadian accent

i like but i m in tunisia if you send me this beauty

dude looks a bit like, and talks like dr. evil
