Dimarzio "Acoustic Model" Pickup DP130, works on a variety of acoustic stringed instruments!

From Dimarzio:
The Acoustic Model™ is a piezo-electric transducer that can be mounted in any location on the guitar's top. A non-hardening putty is used to mount the pickup, allowing simple installation and removal. Every acoustic guitar has its own balance of highs, mids and lows, and it's easy to experiment with the position of the Acoustic Model™ to determine the spot that achieves the best tone for your taste. It can also be semi-permanently mounted on the inside face of the guitar and connected to an acoustic endpin jack, so it's practically invisible. The Acoustic Model™ works on all steel, bronze and nylon string instruments.

Dimarzio "Elemental" acoustic Guitar Pickup

From Dimarzio:
What comes to mind when you hear the Elemental™ are words such as “warm” and “friendly”. It's sensitive to differences in picking attack, and “hears” the change in tone as the right hand moves along the string length. This makes the Elemental™ particularly suited to finger-picking styles with small and medium-size guitars. Like the Super Natural Plus™, the Elemental™ installs easily with foam-insulated mounting brackets. Twelve adjustable pole pieces allow precise string balance, and there's a convenient slide volume control and 12-foot cable.

Dimarzio "Super Natural Plus" acoustic Guitar Pickup, with woodgrain finish! DP136

From Dimarzio:

The Super Natural Plus™ is just what its name implies–it goes beyond ordinary-sounding acoustic pickups. The Super Natural Plus™ is voiced specifcally for dreadnought-sized guitars, where our combination of incredibly crisp treble and tight bass response will allow acoustic players to deal with real-world problems of feedback and muffled tone. The pickup is built into a plastic cover molded to look like dark-grained rosewood. It installs easily beneath the strings, with shock-absorbing foam lining the inside edges of the mounting brackets to keep the Super Natural Plus™ in place and protect the soundhole.

Dimarzio "Virtual Acoustic" acoustic Guitar Pickup, DP138.

From Dimarzio:
The Virtual Acoustic™ uses the same technology as the Virtual Vintage® line to create a pickup that's practically noise-free even compared to humbuckers. The sound is both warm and open, reproducing the natural dynamics and tonality of steel-string guitars and enabling the Virtual Acoustic™ to capture the character of the particular instrument it's mounted in. Like the Super Natural Plus™, the Virtual Acoustic™ installs easily with foam-insulated mounting brackets, which can be cut down in order to accommodate guitars with smaller soundholes. Twelve adjustable pole pieces allow precise string balance. It also has a volume control with a compensated tone network–to minimize tone changes when the volume is adjusted–and a 12-foot cable.

Recommended For: All steel-string guitars with sound holes measuring between 3-11/16” and 4-1/8” (94-105 mm) in diameter.

Dimarzio "Model P" Bass Pickup, in Black. DP122

From Dimarzio:

by replacing its stock pickup with a DiMarzio® Model P®. This hum-canceling two-piece pickup brings big, punchy sound to Fender Precision Bass style pickups. The DiMarzio® Model P® accurately reproduces the sound of your bass with added gain and solid tone. DiMarzio® Model P® pickups cut through the band without sacrificing bottom-end power. Gutsy mid-range provides growl when the bass is pushed hard. Combine the DiMarzio® Model P® with a bridge position DiMarzio® Model J™ and experience any tone from a tight mid-range punch to a warm bottom-end with bright, clear attack.
