Review: Muff full off METAL! - Wowiee! Remember the first time you did a burn out? Here is the short review: Need distortion? BUY IT. This this is so metal. Need distortion on distortion? BUY IT. This thing is so metal. Need to make a synth scream like your LFO is on fire? BUY IT. This thing is so M-E-T-A-L! If your looking for overdrive, or subtle, look somewhere else. Joyo Uzi works well for that kind of job used lightly... This thing? Oh my, look at what I can do, all boosted to the hilt with an electric mistress pushing from behind delivering a whole dump truck full of crunchy distorted synth bliss. Guitar? YUP, shred that too. Me personally? This hunk of metal just turned my Brute2S patch bay into the dream machine bed the Doom Eternal sound track was conceived on. Im on to you Mic Gordon.
Review: Metalheads ONLY. A very nice addition to my collection. - It's for metal, baby. Don't expect any classic rock or blues. This pedal, however, is "fizzy" as opposed to "crunchy" and if you use your neck pickup, turn the tone knob on your guitar so it cuts the treble, your in Stoner Rock solos heaven. The boost is useable, but your settings will be very limited on the boost for it to be anything more than effective. If you max your knobs out, it will be annoying. There's a good video of what you can expect from this pedal, and the video pretty much shows the (useable) settings that are useable. The video is on you tube, and is by "ProGuitarShopDemos" - do note he's using a 7 string at the beginning of the video. I'm not sure if desertcart will let me post a link to the demo, but here we go: https://www.youtube.com/watch?v=CZ03ekeVbso

## Questions & Answers

**Q: Can I use this on my bass?**
A: used it for bass and i got a great fuzzy tone. just depends on what you’re going for.

**Q: I primarily play death metal with alot of fast speed picking. Does the metal muff have decent clarity for a high gain pedal?**
A: I achieved it playing with the settings of the amp. Bass mids and highs. The pedal is set almost to the middle and the gain around 10 oclock. This gives the good sound and notes clear. Otherwise it is a riff pedal. As the dist is fuzzy.

**Q: Can i use a 9v charger for this pedal?**
A: Yes you can.  It runs on a standard 9v "BOSS" style adapter which is used on 95% of pedals.  We also have them if you need to add one. Matt - Seattle Guitar Store

**Q: Even though the newer ones dont say its made in the usa are they still made in the usa?**
A: Yes they are !
