Hi all, I have a lawsuit-era Japanese Jazz Bass with a broken pickguard screw embedded in the body that I need to deal with. It’s a narrow ~2 mm wood screw. A previous freehand attempt to drill it wandered slightly into the body, so the screw remains in place and is now blocking the hole. It’s...

Hi all, I recently picked up a made-in-Japan lawsuit-era Jazz Bass and I’m trying to identify the tuners or find a true drop-in donor/replacement. The tuners are sealed style, not vintage cloverleafs. Details below: Rectangular baseplate with 4 mounting screws Screw spacing...

I have an instrument with a very complex onboard preamp circuit that needs some TLC. Does anyone have a recommendation for someone to tackle this in the DC DMV area? I'd really like to go with a well-vetted expert for this. It's vintage and has sentimental value, so I need to get this right the...

Attempting first ever neck reset on a plywood englegardt bass. Got the neck off, joint looks very very sloppy. And I can’t get both sides to seat flush, where are the places I should add/remove material.

Hi there, fellow bassists! I have just started overhauling my bass(es); complete strip down, shielding, rewiring, and so forth. Now I've already hit a point where I'm a bit baffled, and it's about the output jack and how to get it out / proceed. Search, including image search, did not yield any...

Howdy folks. I have an 800RB I've been using and gently rehabbing from a long life of touring in a punk band. After fixing a variety of issues like a broken volume pot (internally and externally), a flipped connector on the preamp voltage supply (which caused me to blow up a few resistors in the...

Hi, Anyone have success with repairing an A/C adapter where the wire broke next to the block as shown in the picture? Worth a repair try or simply buy a replacement A/C adapter? The Triad adapter is for an Audio Sprockets Tone Dexter (version 1), It's a large pedal for acoustic instruments...

How would you get rid of the rust on this G&L MFD pickup pole piece(s)? It looks like it isn't just on the top - it goes into the hole.

This is a reboot of a thread from 2010. A lot has changed in the past fifteen years. Sadly, many of the luthiers recommended in that thread have closed, moved out of the area, or passed away. So I wanted to see if there are any new recommendations. I've got some basses in need of a skilled...

I bought an used rumble 200 about a year ago. So I've been using it mainly at home, but also for small-medium gigs, 3 or 4 in the last 6 months. Recently, after a week without using it, I started hearing some volume fluctuations, just like a cable about to fail, so yeah, at first I though it was...

Hello! Recently noticed some rattling inside my cabinet and it appears a plastic white piece had fallen off. No idea what it is and how it impacts the cab. I'm wondering if anyone has had experience with this. The cab appears to be working fine, but I don't want to cause further damage if...

I have an Aria Pro II Detroit MK2/5 5 string that I purchased, stripped to the body and neck, then modded with all new parts. The neck has developed more relief than the truss rod can correct. It’s been suggested (in a related post here on TB) that I try having the neck steamed flat, and I may...

I always wanted to upgrade these but didn’t feel like there was a problem to fix so I let it go.. I now have a problem…the peg itself is bent …the treble side g string timer. Still plays and holds a tune well but I’m nervous it will fail at the worst possible time In 2024 is there any...

My search for this simple part is nearing an end as it looks impossible, and the amp is about to go back to GC. I just purchased it used, fantastic amp, but the foot pedal was a big deal as it replaces all the individual ones I'm using plus more. But it's not usable because the input jack for...

For the second time in the last couple of months I've had electronic ground buzzing from an active piezo bass that I bought used. A touch of the hand reduces the noise. The first bass I took to a local shop that has good reputation, and they returned it still buzzing. A second trip and the tech...

Hey everyone, New here to this forum and relatively new to amp repairs. I have a late 90s Trace Elliot 1001 100w head that works and sounds great except for one issue: there's a rattling sound that I can hear physically from inside the head, and also through the signal a little. This is...

Hi all! Thanks for stopping by, I’m trying to find a schematic for a thunderfunk 750a I recently acquired, issues were advertised, now I get to fix it. However, I can’t seem to find schematics for it anywhere, the few I’ve found online or in other threads here are for the 420 or 550. Any help...

Heya, a new-ish bassist here. A worrying event happened as I accidentally placed my bass against the wall at a weird angle and slid off onto the left and landed on the tuning pegs. The biggest concern is that the floor is marble. Picked it up quickly, played a few notes and found that all of the...

Not sure if anybody has had a similar issue, but I figured I would share my experience. Last night I was going down the stairs to the basement for a rehearsal. My B6 was in a backpack over my shoulder, and my bass was in a gig bag. I slipped and fell down the stairs on my back. (fun) The B6...

Looking for any recommendations on where to send a pedal for repair in the lower 48 - I've reached out to several of the folks mentioned here in archived posts and they are either too backed up or they don't do repairs any more. The maker is happy to provide parts and a schematic but won't do...

Hi there! My first post here…I joined on Gollihur Music's suggestion (Mark), with a specific question: I own an iAMP 800 which I love, but that's no longer sending power to my EA cabs… The preamp section works, and I can play and listen through the headphones jack I found an amp repair tech...

Hey, So my grandparents i guess bought my dad a crate b10 back in the day for his acoustic guitar. But, the speaker was replaced with something wimpy and not for bass whatsoever. So, today I just plugged the positive and negative wires that went to the speaker and attached them to a female rca...

I have this old Kay that needs some seams glued. No problem with the edges - hide glue and clamps. What is the best way to hold the vertical seam at the corner closed? I was thinking that placing a heavy object on it might work, but I’d like to make sure I’m not missing something.

Hey all: I have a 1999 Ric 4003 that I want to have some work done on that is beyond my expertise. Needs neck work (cannot be straightened despite new rods, end of fingerboard lifted at one point; probably needs fb removal/neck sanded straight, binding is damaged/has fret sprouts and needs...

Hi folks, I thought sharing my (spoiler: positive) experience here might be of interest to people in the MarkBass or compact Class D community so I'm making a thread. Background: Just under a year ago I obtained a LittleMark 250 BL head used via Reverb; it was my first Class D head so I was...

After some advice. Hoping to upgrade my pickup shortly and I'm a bit of a faffer so will give it a go myself. In work we use this solder, would that be ok for wiring up a pickup or does it need to be a higher spec or a thinner gauge? Thanks in advance

I am trying to fix this used violin bass and it currently makes no noise at all. It has some very ugly solder connections and unfortunately the wiring does not completely match any Hofner diagram I could find. One of the yellow wires on the second volume knob (right) were connected to the bridge...

Bought a used 115LF recently. At a gig about a month ago, one of the amp inputs on the cabinet stopped working entirely (zero sound). Switched to the other input which worked for about month and now that one has crapped out on me too (again, zero sound). So now, no sound from either amp input...

Hey y'all! I bought a Digitech RP21D pedalboard years ago on eBay—it was listed as in good condition, working, etc., and when I got it, I confirmed that it turned on, could have an instrument run through it, etc. Then life stuff happened and I put it away... until the other week. I plugged it...

I recently acquired a used fretless Fender and according to my tech during the set up, the truss rod is completely frozen. He can't tighten or loosen it. He says he got the set up ok for now, but if it does go weird on me in the future I might be looking at a new neck. Any suggestions to...

Hey CO peeps, I live in the Springs and need to find a luthier who isn't terrified of active electronics or more than 4 strings. I just need the common services for now - electronics repair, fret leveling, etc. Would prefer someone in El Paso County but I can go to someone in the Denver or...

Hi all, If you can't be bothered to read the majority of this post, fair enough. However, please be aware there's an issue with the K series speakers bricking themselves and making themselves unrecoverable. This can be avoided by updating your firmware. Please do this in order to not end up...

Polling because I'm curious where folks here land on this. I suspect that users of this site are more heavily skewed towards the self-sufficient end of this spectrum than bassists as a whole, but let's find out and discuss. No wrong answers here, select as many as apply to you.

Greetings, The bridge on my Aria fretless acoustic bass guitar is sadly coming off, and I want to attempt a re-glue (short of an outright replacement). Problem is -- the instrument has f-holes instead of a large enough soundhole, so putting clamps through the soundhole isn't an option. I have...

After finishing a Fender Parts bass, I was putting on some strings and working on set up when the Bass side of the nut just fell right off! It's a 99 MIJ Jazz neck that I had spend quite sometime looking for. Maybe the nut was broken before hand, maybe it was just it's time. In any event I'm not...

I got this Fender Meteora from an ebay auction for a fantastic price with the obvious draw back that the previous owner (or factory worker, it looked brand new with all the stickers and trappings on it) had dropped and cracked the finish on the bass wing. Everything else about this bass is...

Hello all! I was hoping someone could give me an idea of what I might expect to pay for this repair. I was putting up my bass and I had it strapped to a small dolly, I stepped away for just a second and it fell over from a standing position. As best I can tell, the heel just popped out of its...

Can anyone show me what I need to replace this metal nut (see photos)? I have stripped the female threads of the E-String because it took a lot of pressure to get it done in the first place. I don’t see any other way than to replace it. I love this bass and have had it over 30 years. I want...

Hello, looking for some advice! I have a 1973 P-bass that’s been modified significantly, but the neck is original. The fingerboard is a tad worn at the 7th position. This was already a factor when I picked up the bass in ‘90. It’s gotten worse over the years, however - and now playing there...

Hey everyone, would love some opinions on this. Recently I changed my strings on my short scale Serek bass. The new strings completely changed the action, and so after various saddle turns/truss rod adjustments, I am finding that the height from the 1st fret to the 12th fret is perfect, but the...
