Muddy Buddy

The Muddy Buddy is a high quality miniature Practice/Recording Micro Tube amplifier.
Single ended class A shock-mounted miniaturized vacuum tubes at 1 Watt RMS driving an Alnico 8" speaker.





Small tubes, but sizable warmth, presence, power and transparency.
These special purpose tubes were developed by the military to operate smoothly under extreme conditions
with maximum life span.

The Muddy Buddy has beautiful textured and pure cleans making a smooth transition through a wide range of
overdrive and distortion tones peaking into raw 60s style fuzz tones.

The small diameter speaker and low output is perfect for microphones in the recording studio.
Higher impedance Ribbon mics can now be used for beautiful natural guitar sounds.
The mic can pick up more detail without being overloaded by the low frequencies and higher output of larger speakers.




Chassis only version



This little amplifier is an unbelievable powerful recording tool.
The Line out can be used as a quasi overdrive pedal or to go directly into a mixer or recorder.
The sound and response from the genuine power tube section with it's super hi-quality output transformer
leaves typical battery powered distortion pedals behind.
Away with fuzzy unnatural toy-like character - welcome natural and musical even-order harmonic single-ended power tube overdrive.
The 8 ohm speaker output can also drive larger speaker cabinets.


Custom wood cabinets and colors available.

Eastern White Pine

Curly Maple

Quilted Maple

Available also as chassis only version.


As with all Siegmund Amplifiers, the speakers are installed already 'broken in'.


Note: The first few Muddy Buddy's came equipped with Weber's 6" speaker.
In April 2006 Weber has discontinued this speaker and the new speaker size is now 8" - same magnet and voice coil diameter.
