Overdrive – Based on* the DOD
®
Overdrive/Preamp 250
This preamp is designed to slam the input of a tube guitar amp as well as add distortion. This increase of input level causes the
amp to distort in such a way that guarantees a visit from your mom, who obviously does not share your enthusiasm for distortion!
For several guitarists, including Yngwie Malmsteen, the Overdrive Preamp became an integral part of their signature sound.
Once again the original had only gain and level controls, so your DM4 has knobs to spare. Fear not! You may now approach the
EQ. When used tastefully, you’ll bring a tear to your momma’s one good eye. Or, you can go for the extremes and start looking
for a new place to sleep. We’ll trust you on this one.
Screamer – Based on* the Ibanez
®
TS-808 Tube Screamer
®
From Stevie Ray Vaughan to Michael Landau, the simple Tube Screamer is the overdrive heard ’round the world. This medium-
gain pedal was introduced in the early ’80s, and in many blues circles, you’re not allowed to solo without one. Over the years,
Ibanez issued several variations of the venerable Tube Screamer, but none have reached the fabled status of the TS-808. The
MID knob on the DM4 acts like the Tube Screamer’s tone knob. In addition, you can shape your tone using the BASS and
TREBLE controls. (Or leave these in the 12 o’clock position, and they’ll have no effect).
Tube Drive – based on* the Chandler Tube Driver
®
Originally designed by keyboardist Brent Butler to add grind and girth to his Farfisa. Utilizing a single 12AX7 preamp tube, the
Tube Driver delivers the sweet singing sustain craved by guitarists worldwide, and has been a staple of Eric Johnson’s rig since
the mid ’80s. Our model of this classic offers sweet tone with Hi and Lo EQ controls like the original. And as with many of the
DM4 models, we’ve added an optional MID control that allows you to boost or cut the midrange to tailor the tone for you and
your guitar - MID in the 12 o’clock position has no effect.
Boost/Comp – based on* a MXR
®
Micro Amp
This box was used by many a guitar god to “push” the front-end of their non-master volume tube amp, helping them to achieve
that cranked sound at a somewhat-less than stadium level. Our model delivers the same “goose the input of the amp” experience
and serves up a little secret sauce on the side. You see, the Micro Amp had only one knob. That left us with four other knobs
ready and willing to serve. Set BASS and TREBLE to 12 o’clock for the classic sound. MID adjusts the amount of compres-
sion.
