No, the non-electronics guy doesn't do electronics at all. He just refuses to, I don't even know why , maybe just because of what kind of person he is. You know, the boring meticulous type who only does what he does really well. Other than that, he is great. Builds cool guitars (attached see a few of his), does the servicing and repairs (wood and other... mechanical (?) stuff), so I always think of him as the guitar tech rather than the other guy, the soldering dude.Wait, so what part of the pickup swap does the not-electronics guy do?!
If you need help/advice, I think this site is a great resource, but maybe first, we'd have to identify the question or problem in terms that can be addressed as directly as possible.
If you want just more brightness in your tone, there is a list of possible mods. But maybe the JP pickups are part of the reason you can't get there... If the issue is that you want guitar A to sound identical to guitar B, then I think it might be a bottomless errand, especially if you have any nostalgia for the EBMM. In that case, just get the EBMM back (or get another one) and hope that it sounds the same as you remember.
To make your tone brighter: set the tone knob to 10, pick closer to the bridge, use newer strings, adjust the highs and/or presence on your amp/sim upward. If that doesn't get you where you need to be, bypass your tone knob, replace your saddles with brighter-sounding ones, try a different pick, use thinner gauges or brighter branded strings, use a brighter amp/sim. If that still isn't enough, replace your pickups with Dimarzio EVO7's, replace your bridge with something brighter, try the Cool Picks Carbon Fiber Resin pick, get some GHS Boomer 0.008" strings, add an EQ, and deck your guitar out with stainless steel. If that still doesn't work, throw the guitar away, get a piece of slate chalkboard and some steel fingerpicks and just rake them across the surface of the slate. If that's still not bright enough, what I'd suggest next isn't going to be safe and involves staring directly into the sun.
As a matter of fact I've been thinking to buy my old EBMM JP7 back. The main reason I sold it was the EBMM Modern Trem that I couldn't get along with. I eventually decided not to mod it for an OFR and to sell it as is and seek for another guitar, and later regretted that decision, especially after the prices for the EBMM JP have doubled since. The JP16 is not an option for a few reasons.
Thank you for your input, it was very helpful. I will definitely try some and think about others that I always considered as no-go for me.
I think I'll start form staring into the sun
