Rating and Reviews: MXR M133 Micro Amp Pedal

Give yourself a boost when it's time for your solo. It operates with one knob that delivers the right amount of gain when you need it.

Overall: This little pedal has just one knob but it does way more than 3 or 4 different pedals combined. Depending on placement in the chain, I can use it as a boost pedal or a volume pedal or as a pedal to increase my signal strength going into an interface or as a gain pedal. It sort of reminds me of my keeley compressor without the added noise because it also enhances sustain. I don't need insane amounts of gain where clarity of notes is lost or poor technique can be hidden. I like a driven sound with some grunt, much like how a P90 in an SG might sound. This pedal gives me that option. I have decided to pack away my FS2, OCD, Zendrive, compressor and wampler triple wreck in favor of a more subtle tone with dirt. So far, this delivers that.

Sound: Perfect, in everyway Feature: It has one knob, pretty self-explanatory Ease of Use: It has one knob, really? Quality: YES Value: YES Manufacturer Support: Haven't had any need to get support The Wow Factor: YES Overall: It was what I had been looking for. It was the sound I'd always had in my head. I run a Gibson Les Paul Traditional through a Marshall DSL100H and cab. It sounded amazing before this pedal but after it, boy, it sounds like the sound of Christ's amplifier. BUY IT!

Overall: simple 1 knob pedal. I run it in front of my Klonclone (ARC), with a Keeley Katana after that to give me multiple gain stages. just gives that little bit of extra gain and clarity. Nice pedal, does what it is supposed to.

Sound: Doesn't color the sound -- which is what I want. Overall: I play old guitars through old amps -- no second (lead) channel. This pedal is perfect for punching up your lead where you want it; it doesn't color the sound at all, nor does it really overdrive it. Simple, clean, and just what I want.
