Marcel's RCM-4F (PBG build #3)

[Marcel]

For both volume and tone the HB is on 500k and the JB is on 250k. When the switch is in the centre position the HB PU could electrically "see" the JB 250k volume pot.

Action is reasonable at 2.5mm @ 12th fret. Bridge isn't set to any extreme heights or intonation offset.

Can't adjust any extra height out of the JB PU until I can find longer PU screws, as the former P90 screws I'm using now are only just holding on.

Now that you have reminded me Waz about the history of the JB PU I might take up Billb's offer of that EMG Select PU.

Fair enough mate.

Sometimes those J Bass PUP's need a bit of high density foam underneath to bring the level up. The Entwistles that went in were much taller and required a bit dug out of the bottom of the rout as the magnets were thicker and bigger.

Thanks Billb for the EMG Select PU.

I fitted it (the EMG Select JB PU) today and it made a world of difference to the tone and volume of that selector position. The volume is a much closer match to the HB, and the tone is quite full sounding for a JB bridge PU with plenty of top end yet not overly bright in the upper treble range... a real nice JB style PU, and something I'd definitely consider fitting to any JB style guitar.

On a sad note, I now have a buzz when all volume controls are set to zero... a similar level of buzz as you typically get from single coils... and yep, the EMG at full volume has the buzz too... Interestingly the HB and the combined position do not buzz...

Buzz Gremlin hunting is now in process... And my AC15 amp build has 50Hz hum, which I also need to correct...Buggar !

Bugger about the buzz!
Glad the sound is good other than that though
