Barber - Dirty Bomb


Culturejam took one of these apart over at freestompboxes ages ago, I thought I'd add the project here just to keep things ticking.

Here's the description from the Barber website:

"Extremely versatile, high gain distortion, provides wider range of stellar tones.

From ultra chunky, to scooped and back to thick again.

Toggle switch selects mid range character for three distinct modes.

Sweet and powerful Vintage two band E.Q.

Internal adjustable Bass Boost for powerful sub frequencies.

True bypass footswitch delivers clarity when bypassed.

All hand wired in the USA, traditional award winning Barber layout and wiring.

Cascading FET circuit, with MOSFET distortion for incredibly realistic tube quality sounds. "

Ok, now here's an internal gutshot for you:


And a schematic drawn by Culturejam:


As you can see from the gutshot the build quality is top notch. However I'm not sure what they mean "by cascaded FETs". Hmm. It's basically a Marshall Shredmaster with Mosfet clipping diodes... 

It does sound nice though:


Now, what you need to do it go and build a Marshall Shredmaster with switchable diode clipping options..

Here's the freestompboxes.org forum topic for reference: http://freestompboxes.org/viewtopic.php?f=7&t=5592

  1. Maybe because the TL074 has JFET inputs? I count three of those JFET's in series.

  2. The page didn't load the specific content, but pedal reviews that focus on character rather than just specs are more useful than they first appear — a pedal that sounds great in isolation can disappear in a mix, and one that seems harsh alone can sit perfectly in a band context. What makes these write-ups valuable is when they describe how the pedal responds to playing dynamics rather than just listing what it does. The distinction between a pedal that adds character and one that adds volume is often the whole question. There's a discussion on spinrollz bonus about gear that earns its reputation through use rather than marketing — the point about context determining value was well-made. Do you still use it?
