Features
The new A/DA APP-1 Pedal PreampTM is designed by David Tarnowski and is
a no-compromise 2 channel low noise all analog preamp, and the first
product to use his new patent-pending �D-TORSION� Core Technology to
achieve greater dynamics, string sensitivity and a wider range of guitar
tones. You can go from crystal clear clean to over-the-top grind
without touching a single knob on your guitar, pedals or amplifier.
It has more bloom than the most nimble Class-A tube combo amp and can
ring-out single-coil harmonics to frightening levels � all done with
the subtlety of how hard you hit the strings. You can also dial-in
more �squeeze� than a classic germanium diode distortion box.
The APP-1 offers three devices in one: a clean to high-gain
2-channel preamp, a DUAL BUFFER for your effects and a final signal
BOOST for soloing or overdriving your power amp. The Preamp is designed
to serve as an input buffer for all your effects and your tuner, so
plug your guitar effects into it first. Its high impedance input will
not color or load down your pickup�s signal. As a true guitar preamp,
we have added EFFECTS SEND and EFFECTS RETURN jacks on the rear panel �
just like an amp head or combo amp. Your effects chain�s signal can be
adjusted to compensate for any imbalances or losses, and then sent to
our BOOST circuit, which can add up to 20dB more gain with the BOOST
knob. The APP-1 output jack provides a solid low impedance drive with
high signal integrity to connect to your power amp (or input channel of
your head or combo). The two tone stacks and the VOICING pre-EQ
filters are passive, not active, so they naturally shape your guitar
signal without excessive phase shift or impulse ringing. The tone
stack in the A/DA Pedal Preamp has the exact response as a Fender 1960s
tone stack, and guitarists who are used to the Fender taper will be
immediately familiar with how to get the tone they want from the
APP-1. The VOICING is a pre EQ switch that selects the frequency range
that is fed the distortion generation circuit from your guitar. It
can dramatically change the feel, attack, tightness and density of
single notes or chords, or the emphasis of harmonics in addition to
selecting a more British or American tone and response. The unit has a
TRUE BYPASS switch, so it can be completely taken out of your signal
path or used as a BOOST only driver. If you only want to use it as an
effects loop Dual Buffer and BOOST, then select the BUFFER & BOOST
ONLY position on the top middle switch.
The A/DA Pedal Preamp is made in California and is the first
new product for guitarists from David Tarnowski in over 15 years. He
is known for his MP-1 MIDI Preamp, MC-1 MIDI Controller, Miked Cabinet
Emulator, Flanger and many more creations. As with many of his past
products, the new APP-1 could forever change the way guitarists play and
use their equipment, especially overdrive and distortion. With
world-wide patents pending, it�s a new tool and a new era for
guitarists. After all, David wouldn�t be back if he didn�t have
something big to offer. TECHNICAL INFORMATION
The modes of operation of the APP-1 are:
- BOOST only
- BOOST with the dual buffered FX LOOP
- PREAMP + BOOST
- PREAMP + BOOST with the dual buffered FX LOOP
- TUNER MUTE - this silences everything except the signal to your tuner, which is plugged into the back panel of the APP-1
- TRUE BYPASS (Hardwire bypass) This also disconnects the
TUNER so it won't load your guitar signal. The signal to the TUNER
jack is only present in the IN mode and TUNER MUTE mode, and this signal
is buffered.
By switching the FX LOOP in and out, the user can adjust any
gain loss from the effects in he signal chain with the FX LOOP RTN LEVEL
pot. Also when the FX RETURN jack is unplugged, the signal path is
normalized, meaning the FX LOOP RTN LEVEL pot is out of the path and the
path gain is equal to 1.
The BOOST circuit is post MASTER, so the level of the MASTER is always boosted proportionally up to +16dB of additional gain.
