Features:
The Liquid Sunshine is hand made in Dundee Oregon with high
quality components.
Die cast metal enclosures for durability.
3PDT switches for true bypass switching.
Runs for many hours on a single 9 volt battery, or can be powered by
a 9VDC adapter.
Red LED indicator.
Three-year limited warranty.
And it looks cool too.

A special note to
Liquid Sunshine owners: The lower drive knob on the pedal
operates a little differently than most drive controls on other
pedals. The short explanation is that it will always sound a little
scratchy. It is not defective, its simply the way the circuit
works.
The longer
explanation: The liquid sunshine has two gain stages which are
basically fet versions of tube inverters with bypass caps on the
source. One of the stages has a capacitor tied to the lower drive
knob. The capacitor holds a charge at all times, and the fet tries
to keep its source voltage constant relative to the input (or gate)
of the fet. When you turn the knob the pot acts as a variable
voltage divider, and the fet does all it can to keep the source
voltage the same. What you hear as a scratchy pot, is actually the
capacitor charging and discharging. |
Liquid Sunshine
Class A Overdrive - JFET
based design for natural breakup and huge available volume boost.
The Liquid Sunshine will give your amp a good kick in the ass.
Equally useful as a clean boost, treble booster, and overdrive. Responds
well to boosters, and loves pushing your other dirt boxes too.
What is the Liquid
Sunshine?
The Liquid
sunshine is a Jfet based overdrive with graceful breakup and pick
attack, and will not cover up the the natural sound of your guitar
and amplifier.
With two drive
knobs, the Liquid Sunshine allows you to control the character of
the overdrive rather than simply controlling overall gain. The
drive knobs controls two separate gain stages, each with their own
characteristics. The top drive knob pushes the overall
frequency range, while the bottom drive knob accentuates the middle
and high frequencies. Both are very interactive, and allow the
Liquid sunshine to perform as a clean boost or treble booster, as
well as an overdrive.
Why doesn't the
Liquid Sunshine have a "tone" knob?
Unlike a lot of
other overdrives that use diodes to clip an amplified signal, the
jfet circuitry produces no "sharp edges" or hard clipping.
Many tone knobs on overdrives have a very narrow band of useful
settings.
Instead, the
bottom drive knob on the liquid sunshine controls gain and also
alters the frequency response, with many useful settings over a wide
range.
The Liquid
Sunshine now has two internal controls for bass, and treble boost.
Notes from the engineer:
First lets start
out with the definition of overdrive. What is an overdrive
pedal supposed to do? It seems that if you ask 100 guitarists
you could get 100 different answers.
My definition is:
An effect that adds harmonic content, and volume to the guitar
signal that must possess the following three characteristics.
- Graceful
breakup while preserving playing dynamics.
- Pushes an amp
in to overdrive without getting muddy.
- Equally as
useful with a clean or already overdriven amplifier.
There are many
overdrives out there that possess one or two out of these three
characteristics. Then there are others which define overdrive
in a completely different way, by attempting to emulate vintage
amplifiers, often with far more signal compression, obliterating the
nuances of the notes originally played.
Can be powered by
a 9 volt battery or 9VDC adaptor with a negative center 2.1mm barrel
style plug. Current draw is less than 10mA.
