Thanks.
I've been pretty happy with the SD pre and p/u. But with the Nordy sitting in the box, I threw it into the bass this last weekend to see the difference. I would agree that it leaned into Pbass territory unless I cut the mids and rolled up the treble, then it was more ray-ish. It definitely has that low mid thing going as others have said. But it wasn't to my taste, so I put the SD back in. I'll rock this setup for a bit, but I am also curious about the ceramic SD.
From what I've read, both the Nordstrand MM range pickups and the John East MMSR preamp have been designed to get close to the sound of a pre EBMM Stingray. I don't know exactly what this is, I only have past experience with an EBMM SR5 which had a ceramic pickup.
I have rolled back the mids like you have and you are correct it is more ray-ish then, but if you do cut the mids then in my experience you are creating a 'smiley face' eq which doesn't then seem to let the bass cut through the mix, you need some mids to help do this IMHO.
You have a lot more scope and options with the Ray 4, on the Ray 5 you are limited to what pickups you can fit because of the narrow string spacing, otherwise the pole pieces won't line up (might not be important to some people). Apart from the Nordstrand MM5.2 (while is the exact required size) the only other pickup to fit is possibly the EMG as I think their MM style pickup doesn't have any visible pole pieces? I'm hoping Lobster will be bringing some upgrade video's out for the Ray 5 model.
I would say that in Single Coil Mode it does have sort of a P Bass tone (and it is usable), with the other 2 modes I prefer Parallel mode for personal headphone usage (and some live work depending on the song), but generally I like the beefier sound of Series mode.
Do Seymour Duncan do a Ceramic MM pickup that would fit your Ray 4? As you say it would be interesting to hear what that would be like.
I'm going to still pursue the Nordy/John East combo for the moment, in particular the mid-range settings which have a couple of dip switch settings on the circuit board. At the moment it is set at the default low mids.
I also swapped the strings shortly after the install, which has muddied the waters a bit. I fitted some Ernie Ball Slinky's but am not too happy with them which is a surprise as I thought that's what the SUB Ray 4's and 5's came fitted with. I might just swap back to the old strings until I've bottomed out getting the tone right.
