I replaced the ax7 tube with an au7 tube as I am a harp player. With a minimum of reverb and a small delay this amp performs very well. a great value. Do not try to get much gain on the harp. Bass up treble down gain on but way down, good sound.

need that chicago tube tone for harmonica but on a budget. well this is a excellent value. My 1st tube amp and i love it. Got it to go with a fender 15r in a dual harp amp setup. And it works great gives a great low end. to the overall sound. gives me some tube tone needed so the fender15r aint so crispy. And by itsself aint to bad either. has a couple out jacks making it easier to use with a PA. And has a switch for 2 types of amp sounds other than the 2 drives it offers so you in effect have 4 modes of sound to play around with. I highly recomend this amp to the harmonca player on a budget.

This makes a great harmonica amplifier! I have been using a Fender Blues Junior (with one 12AU7 in place of one of the 12AX7 tubes) and this amp sounds better! The tone produced by this amp is similar to the vintage harp sounds of Little Walter. The only feature that it doesn't have is reverb, but it doesn't seem to need any.

I was not impressed with this amp at all. I purchased it about a month ago from the local guitar shop because it seemed like a good deal at the time. Unfortunately, I blew the speaker after a few weeks with never pushing the volume over 4. I used to have a little peavey 8 inch practice amp and that thing was a tank. I would definitely recommend skipping on this amp.

I've never added to these reviews but they do help so here goes. This little amp is great. I was a bit suspicious since it is not really a "tube" amp but more of a hybrid. I have a Spider Jam which is great fun but a bit antiseptic so wanted a little tube amp that had that tube tone/feel and didn't cost an arm & a leg. Well, that's what I got. I am very surprised at the tube tone and the bottom end from such a small unit. I play a Epi Les Paul Ultra and an Ibanez RG-350 through it and the RG really pushes the drive to a point where you almost don't need any additional distortion. The clean sound is great. I also purchased a Digitech RP 150 at the same time because I knew this amp would really shine with some reverb & effects and it absolutely does. I only gave the amp a 4 on features bc it does not have reverb. Add reverb and this would be a perfect little amp. This has really been a pleasant surprise for the price and I have a feeling this will become my favorite amp.
