This is one sic puppy!

Comments about Breedlove Atlas Series Solo BJ350/CM4 Fretless Acoustic-Electric Bass Guitar:

There's not a lot of choices out there for a quality acoustic style bass. There's Ibanez, Dean, Washburn, Laguna as well as other laminate imports. None of them are of a high quality nature even though they are usually pleasing to the eye. I bought and then traded in my brand new Laguna acoustic electric bass in towards the purchase of this instrument. Having owned an domestic Breedlove 6 string, quality materials and craftsmenship were expected even at import status. I was not disappointed. It's simplicity and " meat and potatoes " attitude, demeanor, and character make this a choice player! From it's stylish peghead through it's thick fat ebony fret board, across it's solid red cedar top to the guitar pick shaped sound hole on the top side this bass screams quality instrument at a moderate price. I liked it better then the Taylor or Martin basses being offered. Being a guitar player first and a bass player second I love playing all over the neck with a tendencey to get melodic as oppossed to rythymic, I find this bass an absolute blast to play. Came with the action a little higher then I'd like but what new guitar doesn't. Fretless might not be for everyone but I'm enjoying the challange and discovering new tones everyday! Yep, this is one sic puppy. If it wasn't for the action I'd give it 5 stars but I don't like giving anybody 5 stars anyway. 5 should be reserved for perfection!

Good value for the money

By Chuck Sylvester

Comments about Breedlove Atlas Series Solo BJ350/CM4 Fretless Acoustic-Electric Bass Guitar:

Features: Pretty basic 4-string fretless acoustic bass. decent undersaddle pickup. Sounds pretty natural plugged in. A nice extra is the spare bridge saddle provided. That way you can change the action but still keep the original saddle in case you mess up. Comes with round wound strings. If you leave them on very long, you'll start to get little grooves in the rosewood fingerboard. I replaced mine with D'Addario Chromes, which are easier on the fingerboard and my fingers. They also sound less "zippy" than roundwounds and more like an upright. Mine came in a nice luggage-style hard case, but I believe newer ones are shipping in a high quality pasdded nylon case. Quality & Reliability: Quality is pretty good, although the nut on mine came loose. Easily fixed with a light touch of white glue. Other than that, it seems well built. I used the spare saddle and cut it for the exact action I like- fairly low, but not so low that you get too much fingerboard buzz. Look & Feel: Satin finish isn't as nice as gloss (in my opinion) but for the price, it has a great look and feel. Neck is a bit chunky, more similar to an upright neck that an electric bass. But it plays smooth and easy. This bass is louder unplugged than others I played (Fender, Michal Kelly, Dean, and Ibanez). It also sounds great through a bass amp- lots of lows, but with enough articulation. This instrument is made in Korea. Final setup and QC is done in the States. A very good value for the money. If I could split the starts in half, I'd give it 4.5 stars.


Amazing axe!

Comments about Breedlove Atlas Series Solo BJ350/CM4 Fretless Acoustic-Electric Bass Guitar:

Just got my BJ350 last week and can't stop playing it! This is my 1st fretless bass, but I've tried out many. This is a special instrument. The tone is wonderful - rich and loud acoustically if your remove the side port cover...just what I need to hear my pitch. It takes a while to get used to the dots being the on-pitch if you're coming from a guitar or another fretted instrument. I would prefer fret-lines, but I'm getting the hang of it. The built-in tuner works well, but is positioned a bit far back on the side to see easily. Some say the neck is chunky, but I like it a lot better than my Ibanez SR400's "fast, slim" neck. It's more substantial and I think it adds to the sustain. I don't have big hands. The JDL rod inside is probably helping as well. The tone is miles ahead of less expensive acoustic bass guitars. I don't normally buy guitars with laminate sides and back, but in this design, I don't think it hurts. This axe is build tough like a tank. The L.R. Baggs preamp seems fine but it takes some finesse to play without the "growl" - at least with the round wounds it ships with. Even with them, you can play delicately and reduce the growl and the touch of this axe is superb can control the whole note ASDR envelope- unlike a fretted bass. I?ll be trying some mics out for recording to compare. My K&K Meridian?s goose neck seems a bit short for this big body, to have enough positioning flexibility like for my acoustic guitars. I'm thinking a stand mounted tube condenser or a ribbon will sound great. I like the matte finish ? it hides dings well and is tasteful. The tone is somewhere between an upright and a fretless electric (either solid or hollow body). It's a very cool tone and I think is a new one the scene that makes its own statement - perfect for my more progressive Americana tunes (not Roots). I have a new appreciation for Korean workmanship. The inside looks cleanly executed and even sanded ? no splinters or sharp edges on braces etc. Francesco -
