Worth every penny!

By Kulesk

from auburn, NY

I've had several NOISY heads over the years and this one is, by far, the best "bang for the buck" head I've ever invested in. It gives you total control over your sound, punchy, and extremely flexible. One the best features is the mute button which allows me to tune on stage directly without presenting any unnecessary noise. The tube preamp just adds to the many sounds this amp provides. If you are a working bass player and need a reliable killer head at a decent price, this one is for you!

Everything you need!

By Love

This amp has supplied me with everything that I could ever need. I rarely turn the volume past five, only in outdoor gigs and then it goes to 7 or 8. Sounds do not deteriorate at this point either. It will overpower any instrument and drums if needed. Also, I leave the EQ flat!, all eq-ing is done from my bass controls. Also, I play through an ampeg 4x10. everyone tells me how well I play and sound now.

I've got one.

Like most Yorkville/Traynor products currently being made, the XS400 is full of features and sounds decent (but not better than decent). Bottom line, you can't expect to find better value out there. It's built solid with a warranty to back it up and it won't leave you penniless. In other words, you'll have enough money left to buy that kick-a** Apmeg cab you've always wanted.


Awesome Amp in The Great White North!

By Craig-NcMVL

from The Great White North

I bought this amp at a local music shop along with the traynor 1x15 and 2x10 cab (excellent cab as well). Its awesome and has a great low end, especcially with that cab. The warrenty is great, two year unlimited?!?! Its unbelievable! If you play Rock and like the low end i suggest getting this amp. It lack some of the high end notes I like for the punk, but oh well.


Good, solid amp with great sound.

By Bass Player 49

from Hastings, Nebraska

I've had this amp for about a year now, and it sounds awesome. I used to have a Behringer, and although I didn't have any problems with it, the Yorkville's sound quality is so much better. The tube preamp really gives it a cool, aggressive sound. I would definitely recommend this amp.

I found the amp is right up there with Ashdowns, Ampeg 5 and SWR but half the price with more features.


Great value kick ass amp!

By Muelafunk

from Monterrey, México

Amazing sound at an amazing price. The tube feature it's the best one because it fattens your sound without getting it muddy. The compresor is good, but just good, because you can only adjust the threshold, so when you crank it up the release is kind of slow. The Scoop can help you bring out that high end used for funk but you'll need to add some mids and cut a little on the amp's Bass knob to compensate and not making the sound too boomy. I've tried it in SWR 4x10, Ampeg 4x10 and Hartke 1x15 cabs and the sound's awesome. Great for recording as well since it has line out and pre/post E.Q. with it's Tube D.I. If you want to sound as good as an SWR or Ampeg and save your money do yourself a favor and go get one.


Absolute Best Buy for $$$$

By FreddyFingers

from Sarnia, Ontario

Great sound, great features, great quality for 1/3 the price of an Ampeg...believe it or not, but the sound rivals the Ampegs too...


Excellent Value

By Bassjones-yVLMX

from Fort Wayne, IN

In my opinion this is the best value on the market. Nothing else even comes close. The only thing missing is high-end sheen, but for blues, rock, gospel it's perfect. Probably doesn't have the high-end snap for most fusion or funk players, and the compressor's not too flexible, but this thing pumps out serious room filling booty all night long, and it will not break - EVER! Great warantee just in case


a good honest amp.

I found this amp delivered the goods as specified and more, I found it to be very transparent with great tonal qualities.
