Randall has really taken a hold on the module industry. Them and Egnater have really grabbed the preamp modules and owned the entire market of this industry. You can basically put any type of preamp sound you can think of in this unit, because there probably is a preamp design out there that will do any sound that you want. Now there are builders strickly just for modules.

With this little unit you can take one of your favorite preamp and insert it into the power shell. If you don't like the preamp voicing or toe then simple take it out and try a different one.

Honestly this has been such a breakthrough design in recent years. Since there is no much musical influence nowadays , many guitars have influences that go from one end of the spectrum to the other. Finding and amp that can do all of that is pretty much impossible. Well until now it has been impossible.

SOUNDS

This is really a preamp shell. There are no tones at all in this amp. You must go out and buy from Randall or Egnater the preamp voicings that you want. You have three options to put in the slots provided. Randall has built just about any preamp module you can think of. So it can take come exploring and trial and error to find the right one you want for your sound.

One of my favorite modules is the Mr.Scary from George Lynch. I really love that module a lot. It is thick and fat sounding and turns even the most ordinary guitar into a shredder. If you don't like the preamp module you can always dump it and try something else and a minimal cost. Guys on the internet are always buying and selling modules to find that sweet spot in their guitar rig.

OVERALL OPINION

One great thin that is offered in this shell is the depth control. I wish Marshall and other amps would start putting this standard on their amps. So much of time I find trying to nail that low end which can be absent from a lot of guitars. The shell has the density knob which is basically the same thing.

At new these amps come in at around $770, which isn't bad for a shell power amp combo. You can pick up modules for around $200 to $300 depending on which one it is. They are sort of about the price of a good stompbox pedal so I guess you could look at it this way. You generally add pedals to an amps so you are adding preamps t your power amp.
