If the battery cooks, then it's either shorted or connected in reverse. There's normally a screw terminal pair with red and black wires to the preamp, allowing the connection of a battery snap/clip or wiring it into an existing battery box installed in the instrument. Make sure that any power...

Hi again, James. I just searched all the mailboxes using your full email and got 'No matches found,' which surprised me. I fully expected to find them. I did locate my A/P sketch, which you're welcome to, BTW, let me know. But I suggest that before you spend time on major mods, you try the raw...

Hi James, what you're suggesting would be quite straightforward with many preamps where the volume is connected directly to the pickup and feeds either the preamp input or directly to the jack, via appropriate switching. But with the MMSRs (and Pre EB preamps), the PU needs to retain the...

BTW, I tried to get into Newark for you, but the system won't allow direct UK access.

This is the part in the circuit board from the sister company - Newark Electronics in the USA, so it should be easy to find the mating part. Link Removed

The J-Tone Vol/Vol or Vol/Blend Stack + Bass/Treble stack is fixed to the circuit board with regular Fender Jazz spacing. (1.375" 35mm) The Passive Tone is separate on a plug and has the jack wired to it.

The original Pre EB voicing has the lowest lows and the highest sizzly highs of virtually anything out there. (My experience) Setting the Frequency Wheels in the UNI-PRE to mimic that: (ACW = anti-clockwise / backed off, CW = clockwise / maxed) Set both Bass Freq Wheels ACW, and set the Treble...

For the UNI-PRE: + White to HOT Input + Black & Grey to GND. Black & White are from the coil, Grey is a separate Ground/Screen. This arrangement allows the coil to be isolated from ground, necessary with an Audere where the coil is effectively "floating", connected directly to the electronics...

(Apologies for the delay, I'll work harder to give timely answers) All East units work with 9V or 18V with no change, apart from adding an extra battery and wiring, or a dual battery box. Doubling the voltage doubles the head room or maximum signal level that can pass through a circuit...

I did the same, to find out what they were like. Mechanically they were very good, but it was the quality of finishes and finish inconsistencies that let them down. If the finishes had been reasonable, I was going to ask them to quote to make some knobs for us. Ironically, the boss refused to...

Yes, they will fit, we have a new-ish Squier here.

They are a copy of East knobs, I bought some of each finish a couple of years ago. I contacted them and had a hard job convincing the supplier that they were my design!

Apologies that you've not heard from us ref passive tones. I just took a look but I'm not sure of your email. We had an issue for a while in getting the right pots (custom), we have them now mounted to circuit boards for easy install. (They are a dual A250K, a separate pot & cap for each...

Apologies for the late response, I understand the situation now in that you bought the MMSR recently. We had some issues obtaining the pots for the MMSRs, and could only get 1/4" shafts quickly. So we had to obtain some 1/4" knobs too, and you have some black ones. The 1/4" are specifically for...

Apologies for not answering this sooner. + The MMSR has Pre-EB MM Stingray style EQ, but with some extra low end. * The Stingray voicing, Pre-EB and I understand that all 2B EB EQs have retained the original voicing, has the lowest lows and highest highs around, pretty much, which works well...
