Mine is a BT preamp FWIW

The C in BTC refers to the Concentric Bass/Treble controls.

Those of you with EMG pups in your Quantum, what kind of pickup height do you have going on? My neck pickup is quite low and one screw is stripped, so it's staying that way for now, but I can play around with the bridge pickup. I've read that these work best as close to the strings as possible ...

There are numbers in height millimeters that I'll leave it up to the pros to quote previous posts for but as a generality you want the cover as close to the strings as possible notwithstanding the force that you pluck or strike the strings. In other words you don't want to make abrasive marks on the covers if you can help it. Locate a local guitar Tech to replace the stripped screw. Wouldn't suggest simply replacing it with a larger one.

Thanks for that! Is the point of bringing it in to a tech that they would have a matching screw?
Here's where we are now:

It sounds great as is, but I have nothing to compare it to. Of course I'd like to ensure the bass is set up optimally.

Without digital caliper or proper height adjustment tools you're pretty much left to eyeball it in but unless you have the proper tools and expertise as a lot of us do ( which is a learned ability from trial and error and knowledge gleaned from other sources) I still say find a good local guitar technician that way you can hold him accountable and not yourself if you screw up the screw. I do all regular maintenance on all my instruments but will not endeavor certain mods. Plenty on TalkBass can surely offer better insight.

Well I certainly don't have the expertise; I'll take your advice on this one for sure.

Here’s the quantum manual, it has a section on pickup height

read the manual but it didn't touch on one thing.

this question is for @GeoffGould or others that may have a quantum from the same era as mine.

i have two quantums from 1994 with the bartolini p/u's where the neck p/u is slightly wider than the bridge p/u. they're wired to their original bart preamps. there's a mini toggle switch that the neck p/u is wired to but not the bridge p/u.

one of my quantums has a 3-way toggle and the other has a 2-way toggle.

what exactly does the switch do? and why only on the neck pickup?

thanks!

 

[GeoffGould]

What I remember is using the MBDE in the neck position, and MBCC in bridge. These pickups can be wired a number of ways, but the most useful thing to me was to have the neck pickup switchable. I think it's a triple coil pickup. The switch went from full humbucker to single coil with dummy coil, to parallel hum bucking. I have no idea why the other one is only two-position.

thanks for the info geoff. will play with the settings a bit more to see what's what.

the other quantum with the two-position mini toggle was a goof on my behalf. the original seller mentioned the current pre was the original bartolini so i took them at their word and never bothered checking the control cavity. just opened the control cavity up and, sure enough, it's not the original bartolini pre. mea culpa!

 

[GeoffGould]

that explains the discrepancy!

I've owned them before but was without one for some time. This one came to me last week. It will stay!

Had to let my little man play a bit!

 

[Chuck M]

Beautiful boy. The bass is beautiful as well.

Anyone want to hazard a guess as to the approximate year of this one? It looks pretty new but I am far from a Modulus expert.

 

[drewphishesp]

It'll have the year on the back of headstock one serial number. Year and then 3 digits. Have the serial?

Nah, its on its way though. Should be here by the end of the week.
