Mosrite Mono "300"? Bass

Discussion in 'Basses [BG]' started by yahtzee1280, May 14, 2019.

  1. What I know about it.
    1: It's an early 70s Mosrite 300 Mono with a single pickup in the bridge position.
    2: I have found almost NOTHING about these basses (single bridge pickup 300s) and have only seen pictures of 2 others while googling about it

    How actually rare are these?

    It is in Fairly good condition, with original hardshell case... plays great and has an awesome Big Thump to with that old 70s humbucker.
    I would really like to know more about it since my research has come up with just about nothing other than not very many are pictured and/or published to the internet.

    That zero fret set up is art.

    I would say "Über-rare", at least in my neck of the woods. Never seen that model before. In 20+ years of buying and selling vintage basses in Vancouver (previous millennium) - I think I have ever only seen five Mosrite basses, and three of those were hanging in a New Westminster dealership...

    I've seen them before. Not too common. Mosrite necks are VERY thin, but otherwise they're generally fantastic instruments - typically appreciated most by surf and grunge players in the public eye.

    It doesnt sound as much like a stingray as you'd expect, but its a very cool sound

    The wormy S-curve pg design was initially done by Danelectro (late 50's) and was also gleaned by Japanese guitars in the 60's - Mosrite designs were a conglomerate of the designs floating around during that heady period. My favorite part beside the zero-fret string guide and M-shaped tuner pegs is the blobby shaped neck plate - :thumbsup:

    Maybe try contacting Artie at Front Porch Music in Bakersfield. He has a fantastic collection of Mosrites.

    Very, very cool bass. If I had that it would be tempting to park some more expensive basses and show that one off when I play gigs.

  15. That's a great looking bass. Semie made so many one-offs and custom orders that yours could be a one-of-a-kind build. Those duckfeet tuners are made of unobtanium. Most of the basses equipped with them had at least one tuner break off so be very careful with them.

    Hi! sorry to resurrect an older thread, i thought id chime in. I've got one of these basses. i absolutely love it. they're certainly rare, but not a one off by any stretch. I've seen a few out there (in photos). there was even a two pickup model 350 "stereo" bass, as well as guitar versions of this body style. maybe its the lighting, but yours seems rather darker than mine. do you still have it?
    heres a picture of mine next to, um, another short scale... IMG_0384.jpg

    Thanks for sharing that pic. I don't think I've ever seen that model.

    I've been documenting the 300 and 350 models. Both kinds came as Guitar, and Bass. If they're not purely 1970s (say, 1971 - 74 or 75) then I'd be surprised. It's possible that Mosrite made a few later on, but I've never seen one yet.

    The 300, as shown here, is the cheaper but rarer of the models; Mosrite's 350 (two pickups) model is far more common. I have only 4 different 300 Basses on the serial numbers list (counting the two pictured in this thread.) KB0048 is the highest of the three, so I'm assuming there are at least 48 of them, but these rarely ever show up in the first place. Comparatively, for the 350 Basses, I have 14 documented. 8 with serial numbers (the highest being AB0117,) 1 without a number, and 5 that I don't know the numbers of.

    Here's a ink to my currently newest (June 12th, 2020) update to the Serial Numbers List:

    Mosrite 300 and 350 Serial Numbers? (Guitar and Bass) - Page 6 - mosriteforum.com

    Is your 300 Bass KB0033, KB0053, or KB0063? The number's just after the highest fret. I tried to zoom in, but I'm having difficulty telling what that one digit is.

    @101Volts here is my mono 300 in what i wold call very close to Fender's Mocha/Walnut brown/translucent. i got it locally several years ago at a guitar shop where it was hanging on the wall for almost a year. i couldn't stop thinking about it and since the proprietor was a friend, i traded him a few things and got a great deal on it. it has what i can only assume is the original case, with luxurious green interior and alligator trim. and you were right: KB0063. its a very high quality instrument. it intonates perfectly and has a very even response on every single fret. it feels rather "boutique" especially for a vintage guitar. is there a Mosrite fan club [support group] here on TB? ive put in an 'application" on mosriteforum.com. let me know if you'd like any more angles or info. as i said ive got AB0036 in the mail right now. i would love to see any older photos of it that you may have. i commend your efforts to catalogue these cool and rare pieces of california/ musical history, and ive always found that the individual histories- or pedigrees, or provenances- of guitars are fascinating. who may have owned it, what changes, modifications, it has gone through.
