Yamaha System 19 pre-amp in an LD-10E guitar

Hi Folks Newbie here so please bear with me. I have a lovely early 90's Yamaha LD-10E acoustic in for repair, I think all solid wood? made in Indonesia and a lovely sounding instrument, however the electrics are letting it down. The pre-amp has a PCB populated with SMD electrolytic caps. Many of these have leaked and destroyed the PCB pads underneath. Repairing the traces is nigh on impossible so it looks like I'll have to replace t…

Sourcing Concentric Volume/Tone pots for Sire Marcus Miller Bass

I've had a customer bring in a Sire Marcus Miller with a faulty volume pot. Currently I have an alpha concentric pot installed but it's too big for the cavity with all the wiring, pre-amp etc. and the knobs don't fit the shaft. I tried using insulation to widen the shafts but the discrepancy between the centre of each knob (Upper and Lower) has them bumping up against eachother and moving in tandem. Does anyone know where to source thi…

Tube Preference

We do amp repair in the shop and have been using JJ's for quite some time but recently it seems that the quality is not what it used to be, brand-new tubes are testing leaky, etc. So to the amp guys, what is your brand preference on tubes these days?

Gibson LG-1 1957 fingerboard extension glue will not loosen

Today I have spent the better part of five hours attempting to get the fingerboard extension free on this guitar. I am using the method I have used for dozens of neck resets: 100 watt halogen bulb with heat shields. After a couple hours I thought I was making some progress under one corner, only to discover after some movement that my palette knife was going through the top. I then abandoned that area and have been applying heat and…

There's a lot going on here. So I'll make a list The lightbulb I use is the 250 watt infrared bulb. Not sure how it compares to the halogen. If it is hide glue, I like to add spit to my knife. It's tem…

Grease Bucket Circuit Woes

I've done the Fender Grease Bucket Circuit mod on a lot of Strats and it always works. A customer recently brought in a 335 kit for wiring. It got 3-TV Jones humbuckers, each wired to a Seymour Duncan Triple Shot Mounting Ring, 3 separate volume controls and a master tone with the Grease Bucket circuit. My client wanted to see a clear diagram of the wiring, so I got GuitarElectronics.com to generate one. I've used them several times in…

One other thing (although you've probably already taken care of it): Those caps and resistor can present a lot of exposed hook-up wires. Make sure everything around there is well insulated so that not…

Les paul neck repair advice

Hi, just joined and this is my first post, excited to be a part of the Group! I've been building and repairing guitars and amps for about 15 years but am a better builder than repair person. I have a les paul that has a small but definitely there crack in the neck where the head to neck joint is. It's very tight but does look to be in the wood. Not sure the best method to fixing something like this. I have attached pics for reference. A…

Update, I tried the naphtha thing. It didn't flow in very much, and I tried to get it to open again without much success so I ended up trying to get some CA glue in and now I'm going to let that dry c…

Spline Routing Jig

Hey all! First time posting around here, so forgive me if this has been talked through before, but I'm on the hunt for some jig plans for routing splines on headstock repairs. Thanks so much for any help or direction on this!
