Description

Edit description

Transform your practice sessions with the innovative 'Jam' Jar Amp, a pint-sized powerhouse that redefines portability and creativity for guitarists. Handcrafted in Wales, this 1/4 watt amplifier is ingeniously encased in a genuine jam jar, making it not only a conversation starter but a functional piece of art. Its compact size and playful design belie the versatility hidden within.

The 'Jam' Jar Amp's lid doubles as a housing for the internal speaker, and a cheerful red LED illuminates when you're plugged in, adding an extra touch of charm. With the simple twist-off lid, you have quick access to the 9-volt battery compartment, ensuring that your practice never skips a beat. But don’t let its diminutive size fool you; this amp is designed to perform beyond expectations.

This pint-sized dynamo offers three distinct modes to suit your playing style: as a standalone amplifier with its built-in speaker, as a driver for external speaker cabinets ranging from 8 to 16 Ohms, or as a gritty overdrive pedal to inject character into your sound. Whether played through its integrated speaker or connected to a full-sized cabinet, the 'Jam' Jar Amp delivers a surprisingly robust and rich tone, perfect for those spontaneous jam sessions or intimate living room performances.

Key Features:

Handmade 1/4 watt amplifier housed in a genuine jam jar
Built-in speaker integrated into the jar lid
Red LED indicator for power status
Easy access to replaceable 9-volt battery
Three operational modes: stand-alone amp, speaker cabinet driver, or overdrive pedal
Supports external speaker cabinets of 8-16 Ohms

Glass jar turns guitar amp with the 'JAM' Jar | MusicRadar

musicradar.com

The 'Jam' Jar Amp is an inventive concept, blending novelty and functionality by housing a 2.5" speaker in a literal glass jar. With a modest 1/4-watt output and the ability to drive larger cabinets, it offers a quirky option for guitarists seeking unique tones. The amp's fuzz-tinged overdrive is a standout feature, though the low power might limit its practical appeal. At £25, it's a fun and affordable gadget for those looking to experiment, but serious musicians might find its utility limited. Overall, it's a charming yet niche product for the adventurous guitarist.

In this video, at minute 4:18, Leo shows us two Jam 'Jar' Amps and coments about them. He says "I think these are really cool and you can also hook'em up to your cabinet. They actually run a 4 by 12 cabinet, so that's really awesome.".
