The Ultimate Bass Head!


from Indianapolis, Indiana

Comments about Acoustic B800H 800W Bass Amp Head:

I am a semi-pro bassist, review should not be taken lightly, I know what I'm talkin' about. I started with the Acoustic B450 combo which is the best combo you will find, awesome tone. Later I added an Acoustic B15 Neo cabinet. This was a perfect bass rig, and the B450 stacked perfectly on top of the B15Neo...which made a great looking stack. I loved this rig. But...being a tone perfectionist, I had to get the just announced new B800H amp head. When I picked it up, I spotted a used B410 cabinet and since I lost 2-10's trading in my B450 combo, figured I'm gonna' need it for this new 800 watt rms cabinet. It turns out that the B15 Neo and B410 are a perfect match for the B800. (I live 26 stairs up, so the B810 would be impossible for me to gig with.) These two cabinet can handle the B800H just fine. I put rubber feet on the side of the B15 Neo so I could lay it sideways on the bottome, and the B410 on top. (This leaves about 1/2" on either side of the B410 beyond the B15 Neo.) I am thrilled, excited, and proud of this set-up. The B800H is from Acoustic's new line of products, and improvements have been made. This new line of Acoustic's added a built in (switchable) compressor which functions perfectly, has the same Notch Filter (switchable & adjustable) which is a must for tone fanatics, and a newly added Shape Pad which is great filtering out the highs and putting emphasis on the lows...great for Slow Blues...also good for knocking down walls! I've had this B800H for 3 weeks now, and I'm still fine tuning to the tone(s) I want to achieve my own individual sound. I am amazed at what this head can do, and now to the point I'm experimenting with the Overdrive & Overdrive Level knobs...never thought I would use these, but now I'm finding at the right adjustments just adds even more to fine tune my tone. If you can afford it, buy will never need another amp head...I know I won't. (Unless you play huge, huge outdoor could also get a second B800H 'cause they are made for slave set-up...but what would you do with 1,600 watts?...crazy but possible.) Sorry "other brand fanatics", but the Acoustic products far surpass Ampeg, Fender, Mark Bass, SWR and all the others...why they cost more? Makes no sense to me.

Update on my review.

Comments about Acoustic B800H 800W Bass Amp Head:

I've had the B800H for 3 months now. Everyone compliments its tone. I am in the host band for a weekly blues jam and so I have a lot of bassist of all styles and basses, and they all love my rig. Since my last reveiw I've kept the Acoustic B15 Neo which pushes the lows too much as a stand alone cabinet. I've switched from the 4-10 cabinet to a GK Ultra Lite 15, which pushes mid's & highs (it's not capable of pushing lows so not a good stand alone cab either). However, with the two cabinets hooked up to the B800 I'm getting the full 800 watts and I get complements every week. I bought the Ampeg PF350 as a back up amp and it does fine although with passive pick ups you have to turn the gain way up to get the volume needed...great back up amp at 11 lbs). Anyway, I've used the B800H enough times at gigs now to say this is the best amp head out there at any matter what your style, with all the tone shaping controls, you can get any sound/tone you want. I love this amp and so does everyone else that has tried it. BUT, I must stress that cabinets, speakers, and pick ups also have a huge affect on you're not getting the sound you want with the B800H, it's not the amp, it's you equipment. I use a Fender Getty Lee MIJ Jazz with DiMarzio Ultra Jazz pickups. I will never want for another amp, guitar, or cabinet. ALSO, make sure you know about ohms, parallel, and watts!

Comments about Acoustic B800H 800W Bass Amp Head:

I am a professional bassist of 35 years. As a matter of fact my first nice bass amp was an Acoustic 360 bass amp and cabinet. After selling that rig in the late 70's I think I've tried just about every combination and brand of bass amplification that is out there. When I first heard that Acoustic was making a comeback, I was hesitant because sometimes the "reissued" product is not always as good as the original product. Anyway, I purchased a B600H and B810 Mk 1 series and I was blown away. Recently I had an old Ampeg that I got rid of and thought I'd try this new Mk 2 series out. The B800H is the first part of that and honestly, I think this is the finest amp I've ever used in my career. It's got tons of headroom, it has tons of tone, and the one thing I remembered that I loved so much about my old 360 was the tone shaping ability. This one is better by far. I also like that added touch of built in distortion, a lot like my old 360 had. I set it for solo's or trio rock gigs and it words wonders with my Fender and Gibson basses. So I would HIGHLY recommend this bass amp to anyone who wants a loud, powerful, sturdy bass amp with tons of tone. Now all I have to do is pick up a matching B810 MK 2 cab. It's actually rated at 1200 watts instead of the 800 watts of the MK 1 series. I'm guessing better 10' speakers. Check on out at the store, or just buy it. You can't beat Acoustic warrantee/guarantee either! Back to previous scheduled programming! :)

Outstanding Amplifier!

Comments about Acoustic B800H 800W Bass Amp Head:

I purchased a B800H a year ago, and exactly one year to the day later, It frazzled out on me at a gig. Luckily I had my B200 Combo amp to use as a backup, and the gig was saved. I took the broken amp into Guitar Center in Des Moines Iowa on Monday afternoon, and by Wednesday, I had a brand new replacement delivered right to my house! Not only is the B800H the best amplifier I have ever played through, but the customer service and warranty are simply the best also. I wouldn't play through any other Amplifier. The tone control is awesome, and it has enough power to handle anything you want to do. If one isn't enough, you can chain these awesome things together for even more! Pure and simple, once you play through one of these, you'll never want to use any other amplifier!

Just because its not a well known brand...

Comments about Acoustic B800H 800W Bass Amp Head:

i own a acoustic b100 combo amp and im upgrading to this. i looove the versatile sound the b800h has ! i play anything from classic rock, modern rock, rockabilly, funk and anything in between. this head matched with the b115mkII has the sound to cover that all. with great sounding mids for slap bass (funk or rock) and a rich deep end with that growl ive been looking for. i tried ampeg, Gallien-Krueger , and other brands but they just seemed to be lacking compared to this. the head. cabs and combo amps appear to be well built and sturdy too.


Love it!

Comments about Acoustic B800H 800W Bass Amp Head:

Wow! Is this the warmest, most powerful, most cost effective and versatile bass amp on the market? For my money ,Yes, here's why. First of all this tolex cover and housing is sturdy and durable for road use. The EQ is extensive with built in overdrive, no problem, shape any tone quickly. Plenty of power to deploy two cabinets for bigger venues. I bought the neo 1x15 and 2x10 for an all acoustic stack that is light weight and sounds heavenly and nasty at the same time. Very impressive!
