Yes that can be done. Just replace the existing vol/tone/selector switch wiring harness with a standard passive P/J harness like this one - [url="http://members.ziggo.nl/s.k.wiersma/images_bass_building/Wiring%20diagram%20-%20std_p_j_bass.jpg"]http://members.ziggo...td_p_j_bass.jpg[/url] Wire the hot and ground wires coming from the tone pot to your eq on/off switch instead of the output jack (see pic below). You can use a concentric vol pot instead of two separate vols. You may want to use 500k pots instead of 250k as shown in the diagram. Bear in mind that this new wiring adds a third pot which will change the load on the pickups and may subtly change the sound (to be a little darker).

Here you go

How about a vintage style Fender bridge with threaded saddles? Only a simple BBOT but the threaded saddles provide some flexibility for string spacing. [url="http://www.allparts.uk.com/products/vintage-bass-bridge-assembly-w-threaded-rod-saddles-fixing-screws"]http://www.allparts....s-fixing-screws[/url] Alternatively,Hipshot A and style bridges come in a variety of string spacing options.

In the blurb for the MF Boost on the Moog website it says that the Level control 'does not go completely off' which sounds like part of the problem. I'd contact Moog tech support and see if they can suggest anything - [email="[email protected]"][email protected][/email]

Just sold my BB1100s to Allan. Very straightforward transaction, good comms, prompt payment, a pleasure to deal with. Many thanks Allan and enjoy the bass!

I just emailed David Holmes with a link to this discussion and suggested he join Basschat and explain a bit. So he may be along in a bit

I contacted Allparts who sorted me out. Details below in case anyone else is interested. Fender American hex nut: Thread 10-32 Length 24mm Diameter 9.5mm Essentially the same spec as the cross head nut but 2mm longer so may protrude a bit..

I emailed them re battery life and got this reply: [i]The battery life is around 18hrs of continuous play.[/i] [i]The low battery indicator will give you a 2hr of battery life warning.[/i] [i]The signal will not degrade as the battery life dies.[/i] [i]Yes the unit will switch off once battery is flat.[/i] [i]We are also working on a LightLead that doesn’t use batteries.[/i] Wonder how the battery-less version works?

Hmm, you may well right but this page here says 1/8" - [url="http://intl.fender.com/en-GB/guitar-bass-parts/string-guides-nuts/truss-rod-nut-18-american-series-guitars/"]http://intl.fender.com/en-GB/guitar-bass-parts/string-guides-nuts/truss-rod-nut-18-american-series-guitars/[/url] It wouldn't be the first time Fender got it wrong! The critical specs for me though are the length, diameter and thread size.

Does anyone know if a Fender American hex trussrod nut (like this - [url="http://www.cdguitars.co.uk/fender-truss-rod-nut---american-series-with-allen-head-009-4943-000----0994943000-379-p.asp"]http://www.cdguitars...43000-379-p.asp[/url]) can be used as a direct replacement for a vintage Fender cross-head nut? The cross-head nut is 7/8" long, 3/8 diameter and has a 10-32 thread but I can't find equivalent specs for the Fender USA hex nut (only that it uses a 1/8" hex wrench). Thanks for any input!

[quote name='Andyjr1515' timestamp='1469953652' post='3102184'] Clearly this is the case with a blend pot. Any idea if the same applies with a three-way switch? I've never been quite sure... [/quote] Adding a 3-way DPDT switch to select P - PJ - J before the existing vol/tone controls would work. In the P position the J would be entirely out of circuit and there'd be no additional pot to affect the pickup loading. Yamaha do this with a lot of their P/Js (BB series etc). With a well matched set of pickups this can work really well.

Quite subtle but it won;t be exactly the same.[/font][/color]
