Recommend a high gain pedal for my setup.

All three of those pedals are completely different.

The Rat is distortion with a fuzzy edge. The Beaver is a Muff fuzz and the MXR is more classic ala Hendrix fuzz.

So really it's a question of what sound you are after. For versatility, I would go with the Rat.

 

i have only tried a basic Rat, but when i compared it to a sansamp gt2, modded metal zone, and damage control metal pedal..the Rat was quite lame

 

Monte Allums modded Boss MT-2. Sounds like you're on a budget, and this pedal is leaps and bounds over any other pedal I've tried in that range.

yup. cmatmods will do it for you. You'll have to get the pedal yourself and ship it to him

Even the plain vanilla Sustainia mod without the tri-gain option is killer (if you want to save 20 bucks). In fact, that's the one I used to have. The tri-gain gives you extra versatility though

 

Not all Rats are created equal. Trust me, a good Rat is a very decent distortion device.

 

Lovekraft Chupacabra or Barber's Dirty Bomb

 

You could just get a cmatmods Brownie, it's the best distortion pedal I've ever played. Barber's got a new one called the Dirty Bomb which is pretty sick too.

 

Love my MI Audio Tube Zone...but unfortunately, I like my older 3-knob version better than the newer 6-knob one. Don't know if they're easy to find anymore...

The pedal does great high gain, cleans up nicely with the volume knob and has a great warm, tight chunka-chunka. Great definition with no muddiness at all.
