New electronics for a Pedulla Pentabuzz?

Good evening friends, I had hoped to cast a question before you so that I might enjoy your combined knowledge and perspective.

I've had a 1994 Pedulla Pentabuzz for over two years now. This is a P/J model 'three knob' setup with proprietary Bartolini electronics (more on that in a minute). The controls are Volume, balance and an active tone control with central detente.

For as long as I have owned the bass, the P pickup has been considerably louder than the J pickup. I even discovered that, prior to buying the bass, the owner before I had the bass had mentioned this in two 'for sale' threads on the internet. So this problem had obviously been there when he had the bass, though it was never mentioned when I bought it (imagine that). However, since my typical setup for a bass typically sees me only ever using the bridge pickup, this was not a problem and it does not affect my enjoyment of the bass but it strikes me that this is not right. I have sat on this problem for long enough and decided today that I would fix it, one way or another.

The disparity in volume is massive. It is not simply a case of adjusting the pickups, as I have the P set right down and the J brought up as far as it will reasonably go, and the P pickup is still massively louder. This goes far beyond a 'balance' issue. If I were to sweep between pickups during a performance, I would need to turn my amp down to accommodate the volume increase on the P pickup. Similarly, it is not the battery either as the result is the same with a fresh or run-in battery.

Adding to my suspicions that something just isn't right is that the bridge pickup needs a lot of mids adding to it at my amp to really make it honk like I want it to. Now, there was a gulf of a decade between me last playing a Pentabuzz and me buying this one, but that also strikes me as odd. I almost feel as though the J pickup has some issue, and it's output is correspondingly low and stifled. It sounds great when you juice it up with the amp but it just isn't honky enough to me as standard, and I know and love Bartolini pickups - they should sing with midrange!

The electronics, as I mentioned, are proprietary Bartolini stuff. I will not be able to get a 'like for like' replacement now that Pedulla has closed down for good. I really need recommendations on pickups and a preamp to go into this beauty. I would prefer to stick with Bartolini, if they had an active preamp that would suit the three-knob layout on my bass.

The alternative is that I may speak to John East here in the UK, who is revered for great pickups and for solving problems of this nature, but I expect that a custom solution like that could well work out as being a lot more expensive than a suitable option off the shelf.

I look forward to the input of anyone else who can help me find a way forward here.

I think this is normal because Precision pickups are so much more massive than Jazz pickups -- they are wider and that adds up to more coil. I've noticed that P basses are louder than J basses. (And I experience the same phenomenon on my Buzz bass.)

It's definitely not normal, you should be able to pan between pickups on P/J bass without significant changes in volume.

My Pedulla MVP5 has the same P/J setup with the Bartolini 3 knob preamp and there's no difference in volume between the pickups.

This is more than just the effect of the split coil being naturally louder than the J pickup. As soon as the P is blended it the volume balloons and the j pickup is totally lost. I can only assume that something is spoiling the output of the J pickup and that's why it's so unbalanced.
 
With passive basses it's normal that the J pickup is softer than the P. But the Pedulla system is active, and it should be balanced. I have two Pedulla PJ's (MVP5 and Pentabuzz), a friend has two Pedulla PJ's (also MVP and Pentabuzz) and all the basses pickup's volumes match. There is something wrong with the setup. The bass is probably old enough to try a new Barto pre. The newer basses have a propietary system that might not allow the pickups to be mixed with newer pre's (or maybe this is only true for basses with soapbars).

I assume you have tried reverting the phase? Strange things happen when the phase between the pickups is not correct.

@Pedullist, what can I do to revert the phase short of swapping wires? My intention is probably to swap the whole pickup and preamp and preserve the original electronics should anyone have an interest in them (that's if I ever sell up).



Here is the bass with the last owner I can trace, Marcin Pendowski. He did mention in his 'for sale' adverts that the P pickup was much louder but he has accounted for that in his video.

I plugged into my Phil Jones Big Head tonight for a practice session. The P pickup is still much louder here, not surprises. What does stand out there is that the bridge pickup sounds noticeably better through this unit than it does through my amp, despite the PJB not having a mid control. I'll put that down to just being 'one of those things'.

+1. Or maybe the Jazz pickup is simply going bad?

Even under normal conditions, most J pickups in a P/J setting won't have as much "oomph" as the P. Volume may be the same... but in terms of real power, the usual J in the bridge is more of a side item, not an entree.

Let us know what you end up with! Good luck!

Maybe the J pickup is defective. I would try a new/different J pickup. New active electronics can always be added later.

If you can get in to with John I can't see what a better option might be. He's top dog in my opinion. I would do it right and replace the Bart stuff with John's in a second.
 
Based on what you're telling us it's seems obvious that either your J pickup or its wiring are defective. Why not just take it to a tech to confirm this and take it from there?
It seems that a capable tech should be able to tell you if you have pickup/preamp/wiring issues that he could quickly diagnose. Many of the plastic encased pickups of the 70s and 80s seem to be failing.

My nearest competent tech is over an hour away (Overwater basses in Carlisle). I might get them on the phone and see what they think after having one more look at the guts of the thing this afternoon.

I do expect that the solution will be to swap out old for new, which suits me just fine so long as I can convince Overwater to do the work.
 
Had a bass like yours: three-knob Pentabuzz, P/J pup config. Knobs controlled volume, blend, and tone, with a Bartolini TC3 preamp acting as a boost for a stronger output signal. Many prefer the simplicity and tone of this configuration.

Like you, I was never happy with bridge volume or tone, replacing it with a Bartolini CBJD-3 "Classic Bass" Bright Tone pickup. This pickup had better output, mids, and brightness, offering a nice growl, if wanted. It totally opened up the tone of that bass, presenting many great tonal options by itself or blended with the split Precision pickup.

When my original preamp died, I replaced it with a prewired Bartolini NTBT 2-band preamp. It was the 3-knob version with volume (push-pull active passive), balance, and stacked treble/bass. It had far more flexibility than the stock three-knob circuit, while avoiding drilling into the poly finish.

A 2-band preamp allows mid adjustment without a specific midrange circuit. More mids wanted? Decrease treble and/or bass. Less mids wanted? Increase treble and/or bass. A 2-band preamp is what Gary Willis specifies on his Ibanez fretless models, and what Sadowsky specifies for its renowned active-circuit basses.

The best part of suggested mods above is maintaining stock appearance in terms of knob configuration. It also uses parts from Bartolini, same as original Pedulla, further maintaining stock appearance and pedigree. Keep the original parts if you ever have to sell, including them for anyone preferring to restore to original.

Hope something here helps. Cheers!

Have you contacted Bartolini yet?

They might be able to help and offer something non-standrad (i..e Pedulla-like) - wouldn't hurt to ask....
