PRS MT 15 Amp Reviews

Superb sound in its price range

Nice cleans with boost switch that kinda tries to break it, but has a hard time. Tons of distorsion, sounds really good. Personally will keep gain between 9 and 12 o'clock, which seems fine for hard rock/a bit of heavy metal that I'm playing. Seems really loud, haven't tested in a gig yet, but turned it up around 10-11 o'clock and seems my side of the building heard me loud and clear from the 1st to the 4th floor. Tried it with some custom celestion 70s 1x12 as I am still waiting for the paired box to arrive. Also very nice light show on the ceiling from those colors :) Highly recommended, can't wait to get it out to the gig and blast it. Gig bag and footswitch for free are a really appreciated addition as you don't get those always for free.

Unbelievable

This is my very first real tube amp. I will try to be unbiased here.

Exterior: when I took this bad boy out of the packaging (which was tight and sturdy) I was truly amazed how good it looked. Couldn't find any flaws even on the corners which might be sharp on other chinese-made products.

Sound: at the very first hour of playing with the MT15, I was not happy about the lead channel, because it sounded little too fuzzy for me since I was used to play with amp simulations and combo amps with effect processor. So it was not the fault in the amp - it was me who didn't know how a real guitar tone must sound. After few hours my ears started to adopt this warm and powerful sound, which was nicely cutting through the mix when I was playing with my band. During the next day, the sound was even better and I couldn't be happier. And yes, this boy is freaking loud - I play with my band with the volume knob turned at only 8-9 o'clock.

Clean channel - it must be taken to another topic. It's HUUUGE! I have never heard such a rich and full sound coming from a clean channel. I absolutely adore it.

Pros: powerful lead channel, very chugging tone, cuts through the mix, easy to get good tone by turning all knobs pretty much on 12 o'clock (as Tremonti intended); outstanding clean channel; amp aesthetics.

Cons: chinese-made tubes (not a big deal), takes time to get used to the lead channel for newbie tube-head owners.

I was afraid to by this amp, but glad I did it. It's worth every cent. PRS nailed it!

As for a cab I used Harley Benton 2x12 vertical with Celestion Vintage 30s inside.

Faulty Fx loop, returned.

The amp is way TOO loud for a 15 watt amp, especially on the lead channel.

I was unfortunate to receive an amp with a faulty FX loop that produced awful hum as soon as anything was plugged into it.

This seems to be a common issue. BEWARE!

Best Compact Tube Amp Head

I have a 4 cable configuration gig for different guitars and effects, and this amp has given me the satisfaction of being able to keep every as in playing live at a very confortable size.

After playing with the amp for a long while, I found it very versatile and sound is great!

Keep in mind that preamp tubes are 100% 12ax7 (1 for global input, 1 for clean gain, 2 for lead, 1 effects loop) and getting a low volume lead channel is very tricky; but sounds great!

You might want to change global input (AKA v1 tube) to a lower gain tube (12ay7-70%, 12at7-60%) if you are looking for a broader headroom. But lead channel pair of tubes will blast you out to rock-land like a charm.

Your won't be disappointed with the power tubes section (1 12ax7 inverter and 2 6L6WGC). Sound is awesome and can even use different pre-amp pedals (I recomend "Diezel VH4-2 pedal" if require extreme rock-power) directly into power stage by the effects loop return.

Response is very subtle to changes from the knobs, thou I wish the clean channel had separate gain & volume controls, just like the lead channel.

Being able to switch from 15 to 7 watts is best thing that could ever happen to you. If you would like to keep it lower with the same pre-amp response, I suggest a "JHS Pedals Little Black Amp" as the last item in your effects loop chain.

Minor noise is present, do to the compact size of the actual components inside de amp... but that's is expected when you have such a beast enclosed in a "lunch box".

Keep on Rocking In The Free World!

PRS MT 15

PRS and Mark Tremonti have hit the ball right out of the park with the MT 15. The clean channel remains clean all the way up, and the gain channel is reminiscent of a Mesa Rectifier on steroids. The included carry bag is a tight fit, but does its job well. The only downside to this amp is having an effects loop which isn't footswitchable, however this is only a very minor downside in the grand scheme of things. Overall the PRS MT 15 is a killer amp for not much money, and is perfect for those looking for a small, portable amplifier which packs a huge punch.

excellent amp. very loud for bedroom play. takes pedals well. had very high expectations of it and it delivered.

Great amp for the Buck

The sound is just amazing and the colored lights are really sassy. Furthermore this thing is LOUD. If you are worried that it won't be able to take care of the gig, just don't worry. It will do the job great.

A few things that caught me off guard in a bad way:

I noticed that one of the Tubes and the Power Unit are mounted a bit crooked on the board, which was kinda disappointing - but it doesn't really affect the sound.

Sometimes the amp makes a lot of static and scratchy noises until the tubes warm up.

And it will always make a loud popping sound when turned off, no matter what settings you have (volume turned to 0, standby on etc).
