Boutique pedals are designed by smaller, independent companies and are typically produced in limited quantities. Some may even be hand-made, with hand-soldered connections. These pedals are mainly distributed online or through mail-order, or sold in a few music stores.<ref>{{cite web|url=http://www.keithmcmillen.com/products/batt-o-meter/whereToBuy.php|title=Batt-O-Meter : Where to Buy|publisher=•Keith McMillen Instruments|access-date=18 September 2010}}</ref> They are often more expensive than mass-produced pedals<ref>{{cite book|last=Hunter|first=Dave|url=https://books.google.com/books?id=7DjYrk7Vap4C|title=Guitar Effects Pedals: The Practical Handbook|year=2004|publisher=Hal Leonard|page=204|isbn=9781617747021}}</ref> and offer higher-quality components, innovative designs, in-house-made knobs, and hand-painted artwork or etching.
