FarquariousFjord Posted February 5 Share Posted February 5 Ahoy folks, I picked up an old short scale bass, but it needs a bit of work. I figured I best start with the neck as the action is ridiculously uneven, but I'm unfamiliar with the type of truss rod it has (I've attached a photo). Anyone know what kind of tool I'd need to adjust it? Thanks in advance. The brand/model is RAVER and it says Made in Japan, but those are the only details I can confirm. I was told that it's from the 70s. Quote Link to comment Share on other sites More sharing options...
White Cloud Posted February 5 Share Posted February 5 Pop an Allen key or screwdriver into one of the facing holes and turn: right-tight (less relief), left-loose (more relief). Just like the rod systems featured on Musicman and a few other brands. 1 Quote Link to comment Share on other sites More sharing options...

Any steel rod that fits snugly into the holes around the adjuster is fine (length not critical, but 3-6 inches would be fine...). The rod goes into one of the holes, and the adjuster turned. After a bit, the rod can't turn any further, so it comes out to go into the next hole that has become available. Typically, only a quarter-turn at most at a time, though, so go easy; don't start turning it round and round..! Which way to turn..? Depends on whether the neck needs more or less 'bow'. Turning clockwise will decrease the 'bow', turning anti-clockwise will increase the 'bow'. Hope this helps.

Roger Phillips Posted February 6 Share Posted February 6 Aye, I'd go along with Dad3353's comments. It's like a capstan and by the looks the holes are spaced for quarter turns. Roger in the South Lakes. 2 Quote Link to comment Share on other sites More sharing options...
FarquariousFjord Posted February 6 Author Share Posted February 6 Next stop the saddle, which is also a bit different from what I'm familiar with. There are two screws that raise / lower the saddle and two that move it closer or further away from the neck. In regards to raising / lowering the saddle, can those screws be removed entirely so that the saddle sits directly on the body? With the screws removed the distance between the frets and strings is 1mm at the first fret and 3mm at the 12th fret. Whereas with the screws set at their lowest position (without being so loose they might fall out) the 12th fret is 4mm from the string. Adjusting the other screws is limited as the length of the screws are such that they touch the strings if I try to move the saddle away from the neck. At the farthest setting I can manage (without the strings hitting the screws when played), I'm still coming up quite sharp. I figure I'm either doing something very wrong or maybe these aren't the original screws? I'm thinking about shortening these screws, but figured I should ask here first in case I'm the issue not the screw. Your expertise and advice is welcomed. Don't be shy to call me a dafty if I'm going about this all wrong. Thanks again. Quote Link to comment Share on other sites More sharing options...
warwickhunt Posted February 6 Share Posted February 6 Caveat re 'righty tighty'... never take this as gospel; sometimes it is the reverse. Make an initial very small turn and check (or even keep the bass connected to a tuner to see if the pitch increases/decreases). 1 Quote Link to comment Share on other sites More sharing options...
FarquariousFjord Posted February 6 Author Share Posted February 6 I can loosen and tighten as far as the attached photos, either way the bass is sharp at the 12th fret. E is reading as halfway to F. I want to try going farther, but the screws get to close to the strings and it becomes unplayable. Quote Link to comment Share on other sites More sharing options...
FarquariousFjord Posted February 6 Author Share Posted February 6 I'm thinking maybe I should just pop a new bridge on it. Quote Link to comment Share on other sites More sharing options...
BigRedX Posted February 6 Share Posted February 6 Unless you still have, and want to fit, the original bridge cover which attaches to the the bit sticking up between the A and D strings, replacing the bridge would probably be a good idea. However check the string spacing first as it tends to be narrower than normal on these old basses. 1 Quote Link to comment Share on other sites More sharing options...
FarquariousFjord Posted February 6 Author Share Posted February 6 Thanks. I have the bridge cover, but can live without it if it means I can get this bass into shape. I'll check the spacing. Quote Link to comment Share on other sites More sharing options...
Grahambythesea Posted February 6 Share Posted February 6 That is one crude bridge piece. Makes a Gibson 2 point look sophisticated. 2 Quote Link to comment Share on other sites More sharing options...
PaulThePlug Posted February 6 Share Posted February 6 (edited) Luverly take on a Compensated Bridge Saddle Blade... Shorter Screws for Intonation and Height... I'd hack saw 5mm or so off, or replacements from somewhere like Spaldings Fasteners on the 'bay - I use em for A2 Stainless Grub Screws for bridge saddles.

Pea Turgh Posted February 6 Share Posted February 6 Having recently developed a bit of a thing for odd old basses, I’d be interested in seeing more pictures! 2 Quote Link to comment Share on other sites More sharing options...
Rich Posted February 6 Share Posted February 6 1 minute ago, Pea Turgh said: Having recently developed a bit of a thing for odd old basses, I’d be interested in seeing more pictures! Likewise. I think the kindest thing that could be said about the bridge is 'rough and ready' I would echo BRX's comment, unless you have the cover and are intent on keeping the bass 100% original I'd replace that bridge straightaway.

BreadBin Posted February 6 Share Posted February 6 That's an old Kay, I am fairly sure. I bet it has a plywood neck. Quote Link to comment Share on other sites More sharing options...
jonno1981 Posted February 6 Share Posted February 6 I’m intrigued. If you get a sec, can you post a pic of the bass? Looks really cool! Quote Link to comment Share on other sites More sharing options...
