General rock machine!

Gabor Lajer, 13.11.2018
This amp is my second order from Thomann. Best prize, best shop! Keep doin' it Thomann! :)

The amp knows what it needs to know, well equipped. Two channels are really useful with separated reverb control. The EQ works well, many tones can be found with the EQ pots. My view is that the bright switch on the drive channel is not necessary, I would recommend a booster, which should be switched by a foot pedal instead of switching the reverb. Footswitch is solid, but te LED indicators are missing. Effect loop is useful.

Simply excellent! The clean channel is really nice, sparkling, works great with the built-in reverb. The drive channel is the best rock tone, what I ever heard. Enough amount of gain, but not too much, no muddy or crispy sound, really articulated character, you can easily play blues rock or metal as well. Low noise, but really dynamic sound. Beware the volume of this head, it can be really loud!!!

Really nice and solid build. I think it will handle the years of use! Pots and switches are good qulaity parts, connectors are well-knit.

General impression:
PRS is as good in production of amps as in guitar business. After a ten minutes of playing I knew, that this amp will be my favourite for a long time. The sound is so perfect, I never used clean channels on my past amps, but this is so nice sounding, I will definitely use it sometimes. The drive channel is really good as well, the EQ section acts like a modern higain amp, but the character of the sound and the gain is more like a classic amp. It's like a medium-high gain amp. Works really good with ODs, boosters, wahs. I really offer this thing to those, who play many style of rock music. It is modern, but can sound as a classic marshally thing, or if you use the clean channel with cool boutique ODs and boosters, it's like an awesome JC or a bluesy Fender amp. BTW, I use it with a cutom built 2x12 cabinet, witch is an oversize "Orange-style" box with an Eminence Wizard and a Governor. It is loud as hell!

Excellent sound quality
Low noise
Easy to use
Separated reverb adjustment
Simple rock workhorse with a tons of volume... it is very loud!!!

Missing indicators on footswitch
Power and Standby switches on the back panel (I can get used to it, but it is not so comfortable...)

Precise, yet warm amp

Souly , 14.12.2017
+ This amp's marketing is build on statement, that this amp can help you achieve any sound you need. And I have to agree with that - amp translates precisely all the details of picking and all overtones your guitar produces. Sounds are really variable and controls really simple.
+ It is really loud. On the other hand it may be too loud for home studio, so you'll need to take it into account.
+ It sounds simply great and it great for it's price.

- It produces silent ambient noise at overdrive channel. It is not really annoying, but it may need noise gate when recording with low dynamic volume played.
- Power/stand by are placed at the back side of amp, not really big problem though.

In conclusion I'd say this is absolutely great amp, it would be suitable for stage, rehearsal or recording sessions. Really professional tool and nice price.

p.s. Lot of thanks to Thomann support! Order was processed fast enough and delivery doesn't took much time.
