The Monoprice P-bass

I searched, but I didn't see any threads with anyone who had any experience with the Monoprice bass guitars, so I decided to write-up and post my own experiences with my Monoprice P-bass clone. Hopefully this is the correct forum to post this in.

I've been playing bass guitar only for a few months now, but I'm really enjoying it and I wanted to pick up a second bass that I could haul around, toss in the back of my station wagon, etc, and not really worry about it. My first bass is a black Charvel 3B that looks and sounds amazing, and I get a little bit nervous every time I have to transport it somewhere.

The Monoprice "California Classic" guitars have developed a reputation in my circles for being a solid choice for beginners. When I saw that Monoprice had begun selling bass guitars, I decided to go ahead and order one. I chose the white P-bass clone, or "Pub" model as Monoprice calls it.

When I received it, I went over it and noted several problems with it. Most obviously, the pickups were both angled forwards at a sharp angle.

The foam underneath is angled as well. I don't know if the pickups are angled because the foam is angled, or if the foam is angled because the pickups weren't installed straight.

The second thing I noticed was that the E and A strings were would around the tuners (the tuners themselves are cheap Gotoh knockoffs) such that the lowest wrap was clearly out of the recessed area of the tuning peg. Yes, the stock strings have red silk wrapped ends.

But what really matters is how it sounds, right? I plugged it in and did a little playing. The intonation was spot on, but the action felt extremely high, despite the nut being cut lower than I'm accustomed to. The sound wasn't great - it sounded cheap, although I can't put my finger on what aspect of it's tone made it sound cheap, other than a lack of punch on the low notes. The pickups are not humbucking, and easily picked up the fluorescent light in my office. The tone knob did not change the tone in any perceivable way.

All that said, it still sounded better and played easier than the department store Christmas "bass starter kit" basses I've seen. Which I'm not sure is a compliment or not.

Not ideal, but part of the appeal to me for having a cheap bass was that I could play "Jr. Luthier" on it without worrying about screwing up a nice instrument.

The first step was to change the stock strings out. I put a set of D'Addario Balanced Lights on it for an immediate improvement in tone.

Next I turned my attention to the bridge to lower the action.

The bridge is easily the biggest flaw I found with the Monoprice bass. With all the adjustment screws at their lowest possible adjustment (one of the adjustment screws on the D saddle had the threads stripped out when I got it), all 4 strings were still at 10/64ths at the 12th fret.

As I went to retune the guitar after the adjustment, the A string started buzzing terribly above the nut. Apparently the A string needs to be wound as far down the tuner as possible to get an acceptable angle from the nut, and I hadn't left enough extra when I cut the D'Addarios.

I picked up a Hipshot 3-string retainer and replaced the stock "button" with it, which completely fixed my buzzing issue.

While I had the bass apart, I also picked up a used bridge off a Fender Squier J-bass. Of course the Monoprice bridge didn't have the appropriate screw locations for the Fender bridge, so after a bit of measure twice, drill once...

Next I turned my attention to the stock tuning machines. They are functional, but have too much slop for my taste. I replaced them with a well-used set of Gotoh tuners. The Gotoh tuners were a direct bolt on, and are much nicer to use.

With these parts installed, I was able to get a really good setup on the bass, and it became a nice practice instrument.

But I decided, in for a penny, in for a pound.

I picked up a pair of CTS 250k audio taper pots to replace the mini-pots the Monoprice came with, found an assortment of capacitors in the bottom of my electronic parts bin, and picked up a lightly used DiMarzio Split P pickup.

Here's a shot of the backside of the stock pots; I haven't traced the circuit yet, but it didn't match the P-bass schematics I had. The stock tone capacitor is a .047uF.

I used a hand reamer to enlarge the holes in the pickguard for the new pots, soldered everything up, installed the new-to-me pickups, and put everything back together.

And wow, I'll be darned if this isn't now a great sounding, great playing bass.

Of course, the only parts that are original are the body and the neck. But I had fun, learned a lot, and now have a killer bass that I have less than $250 into. Plus, it has the Monoprice logo on the headstock for that extra "stealth" factor.
 
Thanks for the post and in depth photos. Was wondering about their basses? Saw and played with them at Namm 2015 but was wondering what a "real" off the shelf Monoprice bass would be like if ordered? Obviously, they only take their top basses and re-do the setup prior to showing at Namm.
 
It looks like a decent entry level bass, give or take the things you ran into.

The P pickup angle is common on P basses, IME, and is easily corrected. I see nothing wrong with the way the factory strings were installed, and I might have shimmed the neck rather than replace the bridge. Regardless, it looks like you successfully worked out the issues you had with the bass. You probably could have avoided this by just buying a $250 bass in the first place, but where's the fun in that?

EDIT: It is early and I could be missing something, but that looks like a normal P bass circuit to me.

Nice job! I love messing with low budget basses like this. If the basic components of body and neck are sound, you can pick away at the rest and end up with a great bass for short money. I have an $80 junk Chinese bass I am using to learn fret work on. If I screw it up, no great loss. How was the fretjob on these?

The frets are pretty decent. There were a few sharp edges on the sides, but easily corrected with a jewelers file.
 
FWIW, I still have this bass sitting next to my desk at the office. Currently set up with GHS Pressurewound strings. I play it through a Line6 GX whenever I need to clear my head or while I'm waiting for code to compile.

I'm pretty sure that I would have been better off buying a more expensive bass to being with, but as has been said this was more fun. The work done on the Monoprice bass has given me more confidence in doing my own setups on my much nicer Charvel bass.
 
I assume that, after this post, no one else has ventured to buy one of the Monoprice basses? I just wonder if Monoprice has made any update to their units in the 3 or so years since Daedalus got his bass. Has anyone bought one lately?

So yes, I bought a Monoprice J bass (as of 2018, from their current "Indio" Pubb and Jamm line). I was very surprised after buying the Jazz version, that I bought the P bass version as well. The truss rod needed adjusting, but for the money they are surprisingly good-which is why I didn't hesitate to pick up the other version. I have several Ibanez basses and a 72 Precision, and while the $109 Monoprice are in no ways it's equal, I would have no problem playing a gig with either of them. The bridge is ok, it sustains well, stays in tune. The pickups have a pretty high output for being passive but they're hard to adjust and thecovers do look cheap. The neck width is more akin to the Jazz bass, so it is thinner that the standard Precision. After seeing you can buy an Ibanez Talman with a PJ configuration for $169, I'm not sure the Monoprice is a better value, but I don't have buyers remorse. It does nail the Fender sound especially if you're not A-B'ing it and the pickups are quiet. I've already taken steel wool and took of their "Indio" headstock logo. Took less than a minute. Also came with a padded gig bag. For a foul weather outdoor gig or smoky bar gig, this might be the ticket.
 
Oh, the fret job is OK. The edges are not sharp. Intonation is good. They claim every bass is set up in California after being shipped from China. The paint job on the body was excellent, I like they have a fast, satin finish neck.... but if the bass was set up, the dude doesn't seem to like a lower action. 2 quarter turns of the truss rod with the included wrench and it was much, much better.

I have a few of these from 2019-2020, a J copy and P copy with maple fingerboards, and the $107 5 String. I put GHS Precision flats on the P and 5 string, did some truss rod and bridge adjustment. They seem pretty decent; dead spots are no worse than a Mexican Fender and better than some I have had. If you spend a little time on them they are 'ok'. I use the P with a bridge cover and some foam for covering old Country stuff.

I have a Monoprice Pub Bass in Blue. The basics are nice and solid. The neck at the nut is 42mm and I sanded the back of the neck to get it a bit more comfortable. It's not baseball bat like but a bit more of a handful than I like. I had to do a fret level re-crown and polish and go down the sides of the neck to get rid of some fret sprout. Mine has a Maple fretboard and is actually a pretty nice neck. The tuners were meh so I replaced those with with Fender Highway One bass tuners. Those were not a direct fit so I had to fill and drill but the Highway One tuners covered the holes from the old tuners so it looks perfect and those tuners are nice and smooth. Electronics are junk stock. I replaced the wiring harness with an Obsidian wire Vintage P-bass harness and the pickups with Seymour Duncan SB3's. I replaced the bridge with a Hipshot Kickass bridge which was a direct fit and I added a Hipshot 3 string retainer. Total including the bass was $314 and this P is my go to for gigging. Basically for the price of a Fender cheapy Affinity I have a bass that sounds better than my Fender American P which now collects dust and if something happened to this on a gig I wouldn't freak out. I'd just by another and repeat the process. The one downside is that the pickguard on this bass is not cut to any standard P-Bass pickguard know to man. I have tried several different P-Bass pickguards trying to replace the black one that is on this and now looking pretty shabby. I have written Monoprice to see if I can buy a replacement pickguard from them but they have never bothered to reply. Probably indicative of their service overall. If you can get one of these at a good price and the prices on these can vary widely so do some hunting expect to do some work and sink some more money in to it. If you do you will have a great P-Bass!
