| Diamond Memory Lane
As you can probably guess already, this isn't
your typical analog delay. The Memory Lane has a number of innovations
that bridge the feature gap between analog and digital delays while retaining
the warmth and unique sound of bucket brigade delay devices in an all analog
signal path. Offering up to 550 ms delay time, tempo can be set either
by dial or by foot tap switch. When you don't need foot control of tempo,
you can use the second foot switch as an on/off switch for the modulation
feature simply by switching the small 'feature' toggle switch from 'tap'
to 'mod'.
| Diamond Memory Lane Specifications
- 550 ms approx analog delay time using 2 NOS MN3005’s running at 15V
- tap tempo footswitch control of analog delay time,
OR footswitchable modulation on/off:
'feature' switch allows selection of footswitch for either
tap tempo operation or modulation on/off
- vibrato modulation depth and speed controls
- tilt EQ in delay / feedback path provides subtle control
over frequency spectrum of repeats (from increasingly
dark repeats to flat to increasingly bright repeats)
- 'kill-dry' delay only output for amplifiers with parallel effect
loops
- inserting cable into delay only output jack automatically
removes delay signal from mix output giving separate
direct only and delay only outputs
- true bypass operation for mix/direct output
- pristine signal paths using premium opamps,
polypropylene caps and metal film resistors
- expression pedal input to control feedback level
- ability to use standard 1/4" stereo to two 1/4"
mono insert cable in expression pedal input to insert
an effect or chain of effects into the feedback loop
(can also be used to insert a standard volume pedal as feedback control)
- LED flashes for visual feedback of delay time
- self-oscillating feedback path with ability to shape via feedback
EQ in realtime
- analog voltage supply internally regulated to 15V for
low noise operation and increased headroom in line level effect loops
- rugged genuine Hammond aluminum diecast enclosure
- DC adapter included |
J-Drive
The J-Drive is two independently switchable pedals
in one: a simple clean boost circuit along with the core Diamond Drive
circuit. Both can operated at the same time for a higher gain tone
reminiscent of the Lead + Drive setup of the stock Diamond Drive!
| Diamond J-Drive Specifications
-Clean boost features include a discrete JFET input,
discrete BJT gain and class A output buffer transistors
as well as a simple single knob gain control.
-Drive features include the core Diamond Drive circuit
with
Warmth tone control as well as
increased gain range over stock Diamond Drive! |
J-Drive TR
The TR evolution of the J-Drive integrates even
more functionality and tonal variations into the combined drive and clean
boost concept. In the clean boost section, the TR has an independently
switchable clean boost consisting of a Vishay JFET and germanium (NOS mil
spec NPN 2N388 JAN's) booster that can be changed to a much higher gain
germanium only 'treble booster' by pulling up on the boost section gain
knob. Turning on both the treble boost and drive circuit together gives
some amazing lead tones with just the right touch of germanium sizzle.
They've also added a cool transformer output stage to the overdrive section
which has a wonderful smoothing effect on the upper mids and highs, placing
an inductive source impedance at the amps input as a guitar's pickup would
(but at a lower output impedance so it works great into other pedals as
well as amps).
Diamond's "Close Asymmetry" overdrive circuit utilizes
a Schottky barrier diode for smooth asymmetrical clipping - which combined
with the transformer output gives a liquid smooth sustain with punch. They've
also added a toggle switchable high frequency shelf filter to add extra
'bite' when needed.
| Diamond J-Drive TR Specifications
- true bypass signal path for both the clean boost and drive sections
- discrete clean boost circuit with JFET input/germanium
drive, transformable to a higher gain germanium only
treble booster by pulling up on the clean boost gain knob
- premium audio components, including 2% polypropylene
capacitors, 1% metal film resistors and a Burr Brown OPA2134 opamp
- NOS 2N388 JAN germanium transistor
- post-volume control overdrive transformer output stage
that smooths upper mids and highs
- 'Close Asymmetry' Schottky diode clipping circuit
- switchable highpass shelf filter for additional 'bite',
implemented without additional active components
- battery or standard negative tip 9V DC adapter operation |
Diamond Compressor
Recording studios often use rackmount 'vocal channels',
a mic preamp, compressor, and EQ all in one unit as a front end for vocal
recording. The Diamond Compressor is their take on a 'guitar channel'
... a dynamics and tone shaping tool for live and studio use with low-noise,
ultra-linear signal buffering, smooth opto-based compression, and a versatile
'tilt' EQ that musically shifts overall frequency balance, all in
a user-friendly 3-control package - just Comp, EQ and Volume!
| Diamond Compressor Specifications
- Vactrol opto-isolator variable resistance path as used in
high-end studio compressors for smooth attack and decay
characteristics while preserving initial signal transients.
- Premium audio components, including 2% polypropylene
capacitors,1% metal film resistors and a pro audio grade
opamp (our signal path opamp alone costs 8 to 10 times
what the industry norm uses).
- Post-compressor 'tilt' EQ provides a very musical
tailoring of frequency response - seamlessly transition
from a darker jazz voicing to a brighter jangle,
with flat frequency response at the center detent position.
- Double filtering stage in side chain to eliminate
low frequency modulation while preserving fast
compression response.
- Dual AC capacitive coupling paths for improved
transient response.
- Bi-color LED provides visual indication of depth
of compression.
- True bypass signal path.
- Battery or standard negative tip 9V DC
adapter operation, can be powered from
9 to 24 V negative tip. |
Diamond Fireburst
Thick saturated fuzz with amazing amounts of low-end
- the Fireburst. To add to its utility, Diamond put in a unique, footswitchable
mid-boost eq and pre/post gain circuit that snaps the fuzz into focus and
turns the Fireburst into a tightly focused distortion pedal. The
fuzz and distortion gain and mid-boost eq circuits are all discrete component,
while they use an audiophile grade opamp for an active Baxandall bass/treble
control. The bass and treble controls act independently at extended frequency
extremes (<150 Hz and > 3 kHz), allowing for some very interesting post-distortion
tonal shaping.
| Diamond Fireburst Specifications
- true bypass signal path.
- footswitchable beween thick liquid fuzz and focused mid-boosted distortion.
- premium audio components, include 2% polypropylene
capacitors and 1% metal film resistors.
- all discrete-component distortion and mid-boost circuit.
- active Baxandall bass/treble tone control system with audiophile
grade op-amp.
- battery or standard negative tip 9V DC adaptor operation. |
