BitMo offers several reasonably priced kits
to add additional tonal flexibility to the
stock Valve Junior, priced from between $25
The kits are available through either eBay

BitMo Brat – This mod kit adds a tone control with a pull-switch which adds gain and a
British top boost overdrive.
moving the spots where his components
are placed in a kind of cross-continental,
electronic game of chess. After we heard
what this thing is capable of in “Whoa!”
mode, I’m fine with losing a little headroom in the “Low” position. Keep in
mind that Bruce ships current kits with
winded jams. I’m sure my neighbors hate
this thing, but who cares, I pay taxes
too. It was so nice to be able to get that
familiar fat tone without breaking either
the eardrums or the wallet.
Position two, or “Mo’” mode, imparts
more of a British flavor to the Valve
Junior, increasing the gain and bottom
end. This was a nice setting with the
Junior’s volume knob between nine
and 12 o’clock, offering up a convincing Faces-era Ronnie Wood-esque
medium grind. This would be great for
fat rhythms, and less sustainy, stringier
The capper here is the aptly named
“Whoa!” position. All of the bases can
be covered here – clean-ish, grind, and
distorted, all while retaining the amp’s
new-found, British-flavored thickness.
Park the amp’s volume control at three

volume knob becomes your amp’s chan-

Bruce has managed to take a very good
thing – the stock Epiphone Valve Junior
– and with a relatively simple mod, make
it a thousand times better, taking it from
good to great. This amp and mod combo
would be great for most any live club
situation when a cranked-sounding tube
amp is needed. It’s almost a must for
home recording, although I can’t guaran-
tee it won’t wake up the young ‘uns.
We’d like to thank Epiphone for unleash-
ing the Valve Junior upon an unsuspect-
ing public. The combos go for $150, and
the heads and the cabinets go for $130
each. They are available wherever fine
instruments are sold. For more informa-
tion, visit epiphone.com.
