Thanks @BigRedX, here's a closer view of the Simms circuitry, not sure whether that makes it less versatile, seems pretty impressive but interested in your thoughts?

Any thoughts on what this push/pull pot might be intended for welcome ?

Thanks Andy, yep I know how to install a J-Retro to a normal PUP configuration, I might be wrong but it looks like there are one or two extra wires coming into the circuit above. It’s possible a couple are redundant as the pull pot also appears to be. Either way I’m a little reluctant to pull out the existing circuit until I know what everything does. Might give Simms a call today 👍

This is the bass BTW

Very nice, feels like the car chase soundtrack in an Indie movie 👍

That's helpful, thanks, i pulled out the control circuit and yes it's clearly passive albeit with a pull switch the front volume pot that appears to do nothing. It's not immediately clear to me which wires would go where on a J-Retro, I'm used to simpler things, not sure there's enough info here for anyone to advise?

Thanks @Andyjr1515 and @BigRedX. As far as I can tell this version has the active circuit that balances the changing PUP outputs but a conventional passive circuit, but I will do some checking and photography this evening and report back. Thanks for your help 👍

Thanks Andy, that's my thinking, my main concern is of any potential interaction between the J-Retro and the circuitry associated with the Quads to be honest, any thoughts (can't see there could be a problem but then it's about 40 years since I learned anything knew about electronics so.......)?

Hi @Andyjr1515, many thanks for the above. I have what I believe is an early Enfield fusion FL that also appears to be passive in terms of tone controls (I say appears because I'm not expert on what the circuits do). I'm looking to fit the J-Retro in the front cavity as would normally be the case, the body has a standard Jazz route.

Think it might be this guy.....

He also has this Jaco-related item at a bargain price of $850, frankly I'm not sure if this isn't even worse than the bass https://www.ebay.com/itm/113728005656?hash=item1a7ab7a618:g:Jd0AAOSwxUNhLnWI The face in the drawing really reminds me of someone, just not Jaco

Thanks @BigRedX, that's probably the best bet, I was tempted to install the J-Retro on a suck it and see basis, I think I may see if John has any ideas ahead of doing so 👍

Mad claim (and also untrue)

All the best with the recovery @Telebass, start of a new road perhaps 👍

I think it's great that Bass Direct are looking to stock uprights, despite the fact that many of us play both electric and upright there are very few shops that deal with both at any real quality level. But if they're looking to get into this space they'll need to make sure they have an expert because neither the visuals or the written description encourage much confidence in the instrument, for example 'USA made strings' and 'Quality machine heads', there's a lot of competition at that price point from far more established and far more detailed retailers such as Thomann. But I hope they're successful, seems a step in the right direction 👍

Many thanks for all the above post folks, apologies for delayed response, I was planning on wiring it in this weekend until I read.... ....which is an interesting post, thanks @BigRedX. The tone circuit itself is passive, or certainly appears and responds as if passive (VVT), but I must admit that the electronics in the rear cavity certainly look more complicated than they'd need to be to simply switch on the lights so I assume you're indicating that's a pre-amp albeit preset?

That’s outstanding, rare combination very technical, very busy, and very musical 👍

Seems to be a lot of love on here for Bass Gallery and some hostility towards Bass Direct, my experience is 100% in favour of Bass Direct who have been without problem on around 30 purchases

That’s the BC effect 👌
