Even a better guitar amp

By The Bear-_qi7t

from The gorgeous Commonwealth of Kentucky

I was so pleased with its bass performance, I wanted to see if it would make a good guitar amp like some bass amps due. I put an Eminence Commonwealth 15" speaker which is a pretty accurate clone of the JBL D130F.

Let me tell you that this is the best sounding guitar amp I have ever played through and it loves pedals.

The Eminence Commonwealth is an incredibly efficient speaker so the amp is LOUD with more clean headroom than you can possible imagine.

Having both high and low midrange controls allows me to EQ the amp perfectly for any room.

I play country lead and a lot of fingerpicking stuff and this amp rivals the old Standels with a lot more punch.

When you want to go back to bass, the speaker swap takes about five minutes since all you do is pull off the Velcroed grill cloth and whip out a few screws.

I'm looking for a second one to have in reserve.


Just sounds pretty loud

By Maxx Chiefogo

I will recommend it to newcomers like me who do not know much but just like bass.
Not complicated. SInce I am new, this helps.
I often get carried away by its rich volume. When family complain, I tell them to give me one more minute which never ends. They end up leaving me alone to enjoy my bass.
Best bang for the buck. To me, that is.


Simply Awesome!!!!

By Tony-rfJuA

My old amp blew up, and after reading all the reviews in Musicians Friend, I choose the Kustom KB100. I found out very soon, it's simple, powerful, and has a lot of tone shaping. I am very satisfied. The K100 is definently made my rig a professional outfit.

Great GooglyMoogly!!

By SustainerFreak

from Indiana

Ive owned this amp for a little over a year now, and i must say that I couldn't have bought a better amp to do small gigs with and play in church with.The thing I like most about this amp is that it doesn't include built in effects.I cant stand that stuff. If i want to have effects I'll plug in some pedals,not multi effects pedals either.I guess you could say Im an analog junkie when it comes to playing bass.But this amp is probably the best solid state amp you could get,when you crank it up all the way you get that natural distortion that comes with tube amps. Im not saying this sounds close to a good tube amp,but for what it is it dang sure gets the job done. You can mic it at shows and it works really great for that. I play a vintage modified Squier jazz bass and a big muff pi bass distortion pedal, with a really old no name chorus/delay combo pedal that i bought at a garage sale for five bucks(best deal ever for a sweet vintage bass pedal) through this and it has a really sweet sound that works perfect for the style I play.


Great amp

By Oxfan

from Pittsburgh, Pa

Just opened up my new Kustom KB 100 and of course had to try it out. My plan was to run dual amps through a Tech 21 Bassdriver DI, when I powered up the first notes sounded like John Lodge with the Moody Blues. Old school sound with good depth. This isn't an amp that will be able to put out on full volume without notable distortion but, playing within reason will give good volume and great tone. Lot's of features that make this a great choice, XLR balanced out, with direct out volume control, effects loop and ground. I hate to say, "For the money, this is a good amp" but, for the money it's a good amp,As always, my purchase was easy, Musicians Friend is always my first choice.

Best buy!

By marty tao

from kentucky

I have been playing bass for 25 years and I have used alot of amps.I am not a "gear junky" so when I was looking for a new amp,I wasn't impressed with all the trendy design features of modern bass amps like kick-back cabinets with the the controls on the rear panel and metal grill covers,etc...The Kustom KB-100 was just what I needed! A relatively compact combo capable of delivering solid,versatile bass tone with simple controls.It has all the features I need,like a balanced line out with volume control and ground lift (no more getting shocked at the gigs when i try to sing!)and a simple four band eq capable of dialing in virtually any bass tone you desire!It also has 1/8" aux input and headphone jacks,so no more adaptors!It is quite simply "the best bang for your buck!"
