what are the pros and cons of doing this to your jazz bass?
I like the look of the concentric panel but found that I had more tone by switching my AVRI 62 Jazz to a VVT control panel.
I replaced my concentric knob panel with the VVT panel because I found myself constantly adjusting both tone controls and I never really seemed happy with what I had. When I went to the master tone knob on the VVT panel, it seemed that I had a wider range of tone than with the concentric knob panel and was well satisfied with what I dialed in. If this makes any sense?
@avri62 yes, it does make sense
it seems like a more "versatile" but somewhat like my l2500
also a more "pain in the ass " system to get tone
any other thoughts out there?
PRO: The "coolness" factor cannot be denied.
CON: Unlike the later plastic VVT knobs, the original stack knobs have no reference marks. This might not bother some players, especially the "set it and forget it" crowd. But personally, I don't want to have to start twisting knobs in order to figure out how open each pot is. I don't need individual numbers (à la Fender Strat knobs and Gibson speed knobs), but a simple reference mark is most helpful to me.
I make it a point to set my knobs to where I can tell where they are
disadvantage = knobs sticking out farther than normal, more danger of bumping something
advantage = frees up a control knob hole
I put a stacked knob kit on my parts SX J. I find the advantage the save as having a guitar with dusk volume and tone controls... more control! Plus the kit I used uses different valued caps for each tone control, which I appreciate and feel is the right way to go.
I am pretty much a set and forget kind of player, but I still appreciate the control I have with those dual controls.
Bobby Vega swears that the stacked pot Jazz is the holy tone grail. Can't say I have any experience with it.
During music store demos, I've never gotten the hang of VVT. It just seemed like there were some "magic" positions and then everything else was a bit indistinct. Obviously, if I spent time to suss it out, I would probably get more comfortable with it.
Considering how good Bobby always sounds, his remarks can't be denied, but Jaco said the opposite. I read somewhere that he preferred the more open sound of V-V-T and that he thought it allowed for quicker and more precise on-the-fly adjustment.
I've only done a few gigs with a concentric knob Jazz as I always changed to V-V-T. The tone difference didn't seem to be substantial, but it was more user friendly and easier to deal with live than concentric was so I stuck with it. I went onto Sadowsky later and mine are still set up volume-volume, no blend.
I like the idea of two tone knobs.
I hate that they want to interact.
I LOVE the stack knobs, so much so that I had it put on my custom jazz bass - I adjust them pretty liberally during a set depending on what is needed... I just forced myself to learn the sweep of both tone and volume pots when I got it so that I could reliably adjust on the fly, but also set it quickly and forget it if I want. I typically run my bridge volume at 90%, tone 100%, neck volume at 100%, tone at 70%. I really love how much tone shaping it affords me on a passive bass, and miss it when I play my VVT jazz bass. Also, I rarely play my VVT jazz, and been putting some heavy miles on this beauty
Only con that I've experienced is the knobs will loosen up, and the top knob will grip the bottom, so that both can spin when you just want to adjust one. But this is a simple fix, and I really only have to do that every year or so.
Looks cool--just does
Theoretically more tonally diverse
Convenient if you just solo one pickup or the other
It's fiddly, and that little bit of extra effort compounds a ton when you have to do it constantly
Not a great visual reference to where your knobs are set
While it still is very cool, every single time I've modded someone's J to be VT/VT, they end up changing it back. Every single time. I have, however, only just started considering this as a viable option for a P/J bass, as people are more likely to solo each pickup, or be able to think of each with its own tonal parameter. I've only seen it once though, so I'll wait for a while to see if that guy decides it's cool and practical for everyday use and reports back to me.
Yes, they do. I pretty much have made peace with it, but it can provide a surprise. VVT is easier, but I like the challenge of the V/T V/T because it made me take a fresh look at how I do things.
My 2011 Squier VM Jaguar came with these stock. It's one of the reasons I bought it, along with the block inlays and matching headstock.
One thing I've thought about doing to that bass was to wire it in stereo like a Rickenbacker (which it serves as a backup for), in which case V/T/V/T makes perfect sense.
For the longest time I was intrigued by the idea of dual V/T controls on a JB. But when I finally did the mod on one of my own I was fairly disappointed with the results. It didn't sound bad. But it made far less a difference than I had hoped it would. So I switched it all back to the standard VVT configuration a few months later.
Not to say you'll never see me playing a JB with stacked knobs again. But you can be fairly sure it's packing a preamp if you do.
I like the idea of how clean this would be, but having no reference of what anything is set too would be annoying for me. My PJ with a blend pot has a similar problem, but having a marked knob for the blend pot solved that.
On my pj, after 25 years, they've gotten sticky, if I move one in the stack the other moves. Plus it just seems more complicated than my old jazz, keep it simple, please.
If I understand correctly, in VT/VT setups both tone knobs affect the entire signal coming out...it is hard to isolate them, so you end up still having one tone "control" despite two tone knobs.
