Roland Blues Cube Hot 30W 1x12" Guitar Combo Amplifier with Tube Tone
  • Great amp. Really like the power switch so I can go from 30 watts down to .5 watts. Nice tone and boost buttons also.
  • Well, I have to tell you, the Roland Blues Cube Hot is a really great sounding amp. It can give you jazz, fusion, rock, blues and all those things in between. I really like it; it inspires playing.
  • This is a great amp! Love the way it sounds. Just what I was looking for. Even my friends with tube amps were impressed.
  • This amp will be any kind of amp you want it to be ,absolutely love it ,,Brian Vandekeere was great at assisting me ,,thanks Brian thanks Sweetwater.
  • However there is a very noticeable hiss that appears when the volume knob(not master volume) is up or the tone or boost buttons are engaged.
Fender Blues Junior III 15-Watt 12-Inch Guitar Combo Amp
  • The new Celestion A-Type speaker gives better clarity and bigger lows. It's capable of extremely loud and clean. Also has a nice warm tube breakup tone when needed. It's a jazz and blues monster.
  • The Reverb has been tapered back so it's not over the top. I always had problems with reverb live but not with this one. The highs are less harsh than the previous BJ 3 model which sound wilder, less focused.
  • Fender really did something special here. The tone is much tighter and delivers some shine and growl compared to the older versions. A top notch low wattage amp for the money.
  • Unreal tone and great control. Sounds rich and for 15 watts this amp is loud!
  • The first note I played on this amp I fell in love and new that I would buy one. I love the reverb and the simple controls. I mainly play clean / bluesy so this amp suits me perfectly, even when I only play it at 3. It doesn't sound bad when I turn up the pre-amp either.

What customers say about "Features"
Roland Blues Cube Hot 30W 1x12" Guitar Combo Amplifier with Tube Tone
  • If I designed an amp, this would be it. Simple controls (unlike godforsaken, built for 12 year-olds, modeling amps), reasonable weight (saved my back), loud as hell, or soft as you need it, loves pedals, and most important solid tone. I'm happy all round.
  • This amp puts out the cleanest cleans and just the right amount of dirt (I do mostly blues and some country). I play plugged straight in and often go hours before making a single adjustment on the amp's settings.
  • The power attenuator allows you to dial a great tone at lower volumes. You can dial in a good clean tones. The drive button gives a pretty good distortion sound too.
  • The amp at 15 or 30 watt selection can easily play over a heavy drummer. It has amazing volume for such a small amp. It is a great value and tone wise is superior to it's closest tube competitor.
  • The 12" speaker gives me all of the range that I've been looking for with full deep bass and excellent clarity. The noise level is minimal even at 30 watts. This is a great amp.
Fender Blues Junior III 15-Watt 12-Inch Guitar Combo Amp
  • This amp takes all my pedals real well and the Celestion speaker is a big plus.I own five Fender tube amps but this one is my favorite.
  • The Volume control acting as a "gain" control for the master volume, and the fat switch acting as a boosted second channel to funnel just enough oomph to make lead breaks soar.
  • This little amplifier has a great fat tone for rock and blues with 12" speaker. Surprising power loud enough to be heard in a large music store.
  • My problem is the tone of this amp. It has a fat boost switch, however there is no jack for a pedal switcher. This is needed very bad, as for clean you need one and dirty you need another on this amp. I tried many different kinds of overdrive as well. Just doesn't sound as good as it should.
  • I have tried two of these amps. The first one exhibited an intermittent "crackling noise" like a short in a connection or a tube issue. This amp was exchanged for another one that has a constant "buzz" that seems to be associated with the reverb (it disappears when I turn the reverb completely off).
