Project: RG1527 with an Edge Pro 7 Piezo Mod


Inspired by a thread I saw on another forum, I set about piecing together an RG1527 that would include an LR Baggs Piezo system. I'd already procured a RG1527 body and RG1527M neck, so all that was left was to order a new Edge Pro 7 trem and pickups. Once I had those, I contacted Michael at www.shotgunnmods.net about installing the piezo.

Once finished, the guitar will be:

- 2006 RG1527 Prestige body (blue)
- 2011 RG1527M Prestige neck
- Edge Pro 7
- Crunch Lab 7 (bridge) and Liquifire 7 (neck)
- LR Baggs Piezo system
- Remove tone knob (never use it)
- Move volume knob to the spot where tone was
- Install single pushbutton/toggle switch in old volume spot. Push once for piezo-only, push again for magnetic pickups.

When I contacted Michael, I stressed that I wanted a super-basic, SIMPLE control mechanism for the piezo vs. mag selection. I love the old 2027's, but I didn't need/want controls anywhere near that complex:


Since I already had a body and neck, I procured a minty Edge Pro 7 and locking stud mod (thanks Rich):



Next task was to put some of the parts together and string it up--to make sure they were compatible. They were, and the guitar set-up like a dream:



I shipped the above parts, along with the new DiMarzios, to Michael and he went to work...

First, he drilled-out the old volume hole to accommodate the piezo/mag switch:




Here's the new push/toggle switch installed:
Note... I never adjust tone, and hate.. HATE having the volume knob right under my fingers. So, this gets all that crap out of my way. The way the switch works is it's either 100% piezo or 100% mags. Push once to engage the piezos, push again to go back to mags. Simple. I didn't want any blending, stereo outputs, etc. It's all mono.



Next, the LR Baggs piezo system was installed. Apparently, the EP7's are already set up to accept this system. I don't think much machine work was needed at all:



Here's a closeup of the new LR Baggs piezo saddles:



More pics to come, as this is still an ongoing project. Michael still has to install my DiMarzios and a 3-way toggle, then put the whole guitar back together.

Stay tuned...

Working on my recording skills at the moment, so hopefully I'll be able to update with sound clips as well as pics when it's done. If he gets the switch from DiMarzio this week, I could have the guitar back in roughly a week.

Key will be dialing-in a good acoustic sound so the piezo doesn't just sound like... well... a piezo. I may explore some of the acoustic simulator pedals out there, but hoping I can get a passable acoustic sound with my POD HD Pro.

Re: Project: RG1527 with an Edge Pro 7 Piezo Mod


Okay, I'm behind on a couple updates...

On Tuesday (12/4), my DiMarzio 3-way switch finally arrived, so Michael was optimistic he'd have the guitar finished and shipped out to me by Thursday.



At this point, all that was left was to do the magnetic pickup wiring. The positions will be:

1 - Bridge (Crunch Lab) in series
2 - Neck (Liquifire) in parallel
3 - Neck (Liquifire) in series

I love the sound of the neck pup in parallel for my clean sounds, so the combinations above are all I've ever historically used in my guitars.

Re: Project: RG1527 with an Edge Pro 7 Piezo Mod


Wednesday night, Michael notified me that this baby is done! He sent me one last pic of the final wiring:



Once I get the guitar back in my greedy little hands, I'll upload some full-body shots, and hopefully get some sound clips up on SoundCloud.

EDIT: Looking at the control cavity above, I asked Michael if another tech would be able to figure out the wiring... should I ever want to get the guitar repainted, pickups swapped, etc. He said "probably not." heh

Those of you who know electronics well, take a look in there. See anything that would present a problem for an above-average tech?

Yeah, all my life I've played Ibby's with the 5-way system, but only ever used 3 of the 5 positions (always the same 3). I had never thought about it before, but when I realized that it was a "parallel" humbucker sound that I always used for clean, I figured we'd just hardwire this puppy that way.

Oh dang, it didn't occur to me to ask for that! Fingers crossed that he included it anyway.

Re: Project: RG1527 with an Edge Pro 7 Piezo Mod


Michael (a.k.a "shotgunn") just made a short video demo of my guitar. The guitar should arrive either tomorrow or Thursday, but for now this is just a teaser. He occasionally does these for his customers, especially if the project entailed some new/unique switching or wiring option (which mine did):

YouTube Video: Edge Pro Piezo Mod with Custom Switching shotgunnmods, LLC

He was pressed for time, so the video doesn't showcase the piezo very well. After it arrives, I'll eventually post some sound demos on SoundCloud that really focus on demoing the piezo sounds.

Enjoy!

Re: Project: RG1527 with an Edge Pro 7 Piezo Mod


UPDATE

First, I'd like to say that I really hate shipping guitars. Too much potential for loss, damage, or theft.

That said, FedEx must've done something that jarred the electronics pretty badly. I won't detail the issues here, but suffice to say something(s) came loose somewhere. Both the piezos and mags were affected.

Michael and I are weighing our options right now. He'll file a FedEx claim, and has offered to take the guitar back and fix. However, the thought of shipping this guitar again (with the very company that damaged it, no less) and being without it for an extended period again doesn't appeal to me. Then again, having a less-than-perfect guitar doesn't appeal either.

The guys who run guitarelectronics.com have a physical shop here in Phoenix. I'm wondering if they could diagnose and fix it. Some pretty complex/custom electronics work was done in there... so this isn't a job for your average tech.

Re: Project: RG1527 with an Edge Pro 7 Piezo Mod


FedEx claim has been filed, so now we wait. This will be fixed one way or the other, but we're hoping FedEx owns up to the damage and pays-out some of the insurance. That'll help cover the cost of shipping (again) and the extra labor to fix.

I'm a little nervous about FedEx taking my guitar away to some facility and inspecting it. The damage can't be seen--it has to be heard. Anyone had experience with making an insurance/damage claim on guitar electronics?
