Comments about Washburn AB45 5-String Acoustic-Electric Bass:

I'm giving this bass five stars because it is a great bass, despite not being the bass described/advertised. I ordered this in March and received it in July. The bass looks spectacular with a shine you can comb your hair with; the construction is solid; the acoustic sound is open and clear and the amplified sound is big and rich. HOWEVER the bass I received is not the bass described. The aesthetic differences are actually favorable to me - the hardware is black not gold, which I prefer. The main issue is the bridge. Pictured and described is a one-piece rosewood bridge with an under-saddle ribbon piezo pickup. But what I got are individual rail bridges with contact piezos meaning that THIS BASS IS NOT SUITABLE FOR NYLON-WRAPPED STRINGS and I assume probably not suitable for bronze strings either. I learned the hard way. Before plugging in, I replaced the stock steel strings with a set of nylon-wrapped, tuned it, and played it acoustically for a few days. Sounded great (although a bit on the quiet side for an acoustic) with a nice open sound and clear fundamentals. Then after a few days I plugged it in. the only sound coming from the amp was an ungodly hum. I checked my connections and rechecked the amp with another bass. No, not that. I was just about to return it as defective when I decided to do some research. Turns out that particular type of piezo needs a metal contact to complete the circuit and ground the signal. Washburn's website doesn't mention this nor did the pamphlet that came with the bass. Instead of returning the bass, I figured I would attempt to modify the nylon strings so that the steel core contacted the piezo. Now it works fine but the modified strings slightly alter the intonation and fundamental. Not unplayable but not the greatest. In the future i will restring with flatwound steels to somewhat replicate the acoustic sound I look for. I'm disappointed that Washburn didn't think this through in their design. Also, RE: marketing @ Musicians Friend - PLEASE UPDATE PHOTOS AND DESCRIPTIONS OF THE PRODUCTS YOU SELL so that this doesn't happen again. Thanks for reading.

not sure yet... first one had issues, waiting for replacement

By 1327510

from oakland

Comments about Washburn AB45 5-String Acoustic-Electric Bass:

i took a chance on this one, ordering it sight unseen... and unplayed. i had it shipped direct to my house. it's got a nice neck... thinner than the breedlove. it's also shorter and less fat than the breedlove. the strings are very roundwound... but the overall playability is good, and even... and the sound is good, despite the slotted vs. regular sound hole. there were some issues: - during initial unpacking, i noticed that the case was scuffed up in multiple places... not sure why. - when plugged in, the D and A string output was almost zip... and adjusting the individual string trip pots on the back of the guitar made no difference. - i put on different strings, and noticed that the nut slot for the A string was way too deep.. total buzz and no tone when playing the string open, perfectly fine from the first fret up. it was fine with the stock strings, but noticeable unstrung, and with the alternate strings so... after waiting almost a month, it got returned the day after it was received... and another one is on order... i will update this review when i get the replacement. guitar center was great about the ordering and return, and also matched a lower price... no complaints about the customer service! in the meantime, the jury is still out... hope the second one has no issues, as the guitar is comfortable to play, and essentially what i'm looking for... a mid-priced 5-string acoustic bass.

Try before you buy.

Comments about Washburn AB45 5-String Acoustic-Electric Bass:

I purchased this about a 2 years ago and expected a tobacco sunburst acoustic electric dream bass. When I got it i was surprised to find a yellow-orange sunburst but it looked ok so i didnt let that phase me. It plays very nice, came set up great with its intonation and action. It has decent volume for its thin profile however if played finger style it will not hold up well against an acoustic guitar. Electric this thing stinks. If you want something to plug in this leaves much to be desired. It sounds extremely hot and overdriven, and lacks volume, The only good electric aspect about this is that it won't give you much problem with feed back for and acoustic electric.

Sounds as beautiful as it looks

By Brent

from Sparks NV

Comments about Washburn AB45 5-String Acoustic-Electric Bass:

when I saw this bass i thought it was one of the most beautiful acoustic basses ive ever seen. when i picked it up i noticed the neck is super thin and so is the body. thats better than most ive picked up and the body is too big and uncomfortable. then i strummed it, it has perfectly clear sound with lots of great tone and crisp high ends and deep low ends. when you plug it in it sounds even more clear. this bass it recomended for any style or genre, scince it has a wide viriaty of playability

Not as pictured

Comments about Washburn AB45 5-String Acoustic-Electric Bass:

Very smooth Bass! For the price it didn't have Gold Hardware or Acoustic strings and back plate was putty in color not Black! Called Washburn to check, was told hardware was mixed? Felt black looked better, then what about the back plate? Sounds to me like they are just trying to increase profits! Don't get me wrong it's a nice looking Bass but when you look at the list price you expect as listed!

Wahburn Acoustic-Electric Bass Plugged-in Big Sound

By Mark Snyder

from North Richland Hills, TX

Comments about Washburn AB45 5-String Acoustic-Electric Bass:

I have owned the 4-string version of this bass and was very pleased with the sound of it when plugged in. Great for recording when you want a big bass sound. The fifth string gives you even more low-end joy. Very cool looking bass. The only drawback is the acoustic sound is not very loud and will not keep up with acoustic guitars without amplification. This is the only reason I took one star away. This low price and a bigt sound makes with Washburn Acoustic-Electric Bass a great value.
