Analog Man Bad Bob Booster Originally built by Robbie Wallace - RGW Electronics
In 2010 Analog Man started making this pedal ourselves. They have been available with hand stamped
graphics like our switch boxes until late 2013 when we came up with nice graphics like the original, but in heavy duty epoxy ink instead of a fragile sticker. In June of 2017, we made the logo full color, adding red like Robbie's original!
The Bad Bob pedal is a booster based on the famous and much copied mini-booster "JFET mu-amp" design of Jack Orman
(check out his site to learn more). This design was also used as the basis for most other boutique boost pedals.
It is a class A booster that is capable of driving your favorite tube amp into tonal nirvana! With well over 20dB of gain, the Bad Bob fattens up even the cleanest high powered tube amp.
Do you use a lower wattage amp already on the verge of breaking up? The Bad Bob pushes it over the edge to obtain rich sustain.
Do you like a vintage or modern 30 Watt Class A tube amp cranked to the hilt? If so you will love the Bad Bob...
Bad Bob Booster by Robbie Wallace
Here are some of the features:
- Cast aluminum enclosure with baked-on silver
- Metal Switchcraft 1/4" input and output
- High quality double sided PC Board.
- True bypass switching with special wiring
to minimize external noise.
- 2.1mm DC power jack for use with most
standard regulated 9VDC adaptors (Boss PSA-120 or Voodoo Labs PP2
- Low power consumption!
Under 1mA when off, under 3mA when on, no IC chips, so battery will
last a LONG time.
- Capable of running at up to 18VDC for a
cleaner, punchier tone with more headroom!!
- Awesome after fuzz pedals to add more focus and cut
- Awesome after tube screamer type pedals, brings some low end back.
- Metal Film resistors and coupling
capacitors for optimum tone.
- SIZE : 2 5/16" x 4 5/16", MXR size 1290 or 1590B enclosure.
- Mini Bad Bob size is 1.5" wide, 3 1/2" long, and 1 1/4" tall.
- Mini Bad Bob with battery option is 1.5" wide, 3 1/2" long, and 1 1/2" tall (about 1/2" taller).
New in late 2018 : Drive knob option
The optional DRIVE knob (on the right) is exactly the same as before when turned up all the way. You can turn it down to get a cleaner sound. Down all the way is a totally clean boost. Like many pedals, the drive knob has a voltage on it, so it will make noise when you turn it. You won't be turning it while playing so it's not an issue.
New in 2013 : MINI BAD BOB
Some people really like the tiny pedals, especially when used with switching systems or on boards with very little room. So we can make the Bad bob in the tiny box, with power jack only as there is no room for a battery.
New in 2013 : MINI BAD BOB with battery room
For people who like to use batteries sometime, and want a tiny size boost pedal, we now have the answer. This half-inch taller case allows room for a battery, and the power jack.
Bad Bob in Ernie Ball Volume pedal
We can build the Bad Bob into an Ernie Ball VP Jr 25K volume pedal (6181), with a bypass switch and a power jack. The Bad Bob is a great buffer so when it's ON, you don't need any other buffers before the 6181. No power is needed if you turn the toggle DOWN to bypass the Bad Bob. Why have an expression pedal insert on your booster and have two pedals
on your board, if you can do it in one? For ordering, see our
Ernie Ball 6181 page.
There is a short demo on Facebook. The delay is being used for a
buffer when the bad bob is off. Itís not needed when it is on as the bad
bob is a very good buffer. Note the sparkly Bad Bob clean-up when the
guitar is turned down:
In 2018 we made a batch using polished bare metal cases instead of silver powder-coated paint. We are leaving the metal bare, it may develop patina but the finish won't chip or flake off. We tried clear-coating, but it chipped off too much. We can optionally make a Bad Bob in a normal bare metal box with red hand-stamped graphics like the Mini Bad Bob above. And in late 2018 we got the silver cases back in again, with new option for LESS DRIVE knob!
Here is a comparison of the Bad Bob to my other favorite Clean Boost
DUAL BAD BOB
In 2018 we made a few DUAL BAD BOB pedals by request. You can crank the first one up to add distortion, and turn the second one down as a master volume. We can build these as below with red hand-stamped graphics. Put a note in the order comments area if you want the large/wide (Large Bicomp style, see yellow one below) box, or large narrow (like Bi-Chorus layout) or the small narrow (Mini Bicomp) one, and a color preference.
Small : Sunface Gold, Mini Chorus Blue, Juicer Orange, CompROSSor Grey, Yellow, or bare metal,
Large: White, Gold, Blue, Yellow, Orange, or bare metal.
KLON : The KLON Centaur is not as clear as Bad Bob, it is
more compressed, even at minimum gain. Also the KLON is not nearly as loud at
it's clean boost setting. The tone difference is really noticeable with the
guitar's volume and/or tone turned down a bit - it makes the KLON sound dull in
Z Vex Super Hard On : This pedal is much cleaner than the BB, if you
just a totally clean booster the SHO is probably better. Our optional
DRIVE knob allows the Bad Bob to get ALMOST as clean as the SHO. The Bad
Bob has nice
grit/drive even at the same volume setting as OFF. But the sound is not
useful at a unity gain setting, so it's not a great buffer pedal like
At medium boost, the SHO is sharper and cleaner sounding, the Bad Bob is
bright, has a thicker, richer tone. The SHO is just as loud when turned
the way, and the two pedals sound more similar when cranked up loud as
is really running overloaded by that point. The Bad Bob has a bit less
cranked, I was surprised by this but maybe due to some high end rolloff.
Bob is sort of like a Rangemaster clone (our
) but without the tone change and emphasis of certain frequencies.
Beano Boost (not really a clean boost) : The Beano Boost is a Rangemaster
clone. It will give an amp nice cut and focus, and add a ton of crunch,
how high you have the level set on the pedal. The Rangemaster pedals
tone, boosting the selected frequencies. If you are going for a classic
rock tone, it could be awesome and I like to run my Beano Boost into a
dirt pedal as my amps are usually set clean.
The Bad Bob is a dirty clean boost, it does not change your tone. It has some crunch but gets nice and clean by backing the guitar down (or with the LESS DRIVE knob option). Bad Bob may cause your amp to overdrive
more, depending on how close the amp is to breakup, and how high you have the
Volume knob on the pedal.
