Lo V - Episode II - Pepper Shredder MK II
|
 |
UPDATE:
The design of the Pepper Shredder MK II was changed in many
points. The new design is PCB based (LoV-Standard PCB) and
the 12AU7 tubes were replaced with a 12AT7 in the first two
stages and a 12AU7 in the last two stages. A tone-stack is
now also part of the design and therefor the last stage was
changed to a cathode follower.
Design:
Just like the VanillaOverdrive the PepperShredder is designed
for the use of 12U7 / 12AU7 tubes running at 12 V. It has
one more gain stage than the VanillaOverdrive and it sounds
more heavy but it can also sound soft - but just if you want
it.
Sound:
Pure Heavy but no Nu-Metal ! If used with a real 12U7 the
Pepper will have a little bit more bass but it will work of
course perfectly with a 12AU7 too.
Application:
The Pepper can be used as a tube-preamp / overdrive or as
an booster. If it is used in front of an another amp which
has a full tone-stack it is recommended not to build the Pepper
with a tone-stack too - or just with a "little"
tone-stack. It sounds best if used without a tone-stack. Alos
please keep in mind that each tone-stack needs a little power
to work and the more complex the tone-stack gets the more
power is needed and this power is missing at the end. If you
really want to build the Pepper with a tone-stack make sure
to make it switchable so it can get bypassed if not needed.
How To Build:
Again of course very simple as one can see on the picture
- pure point-to-point wiring. All resistors are 1/4 W metalfilm
types which are recommended for this kind of amp but of course
carbin composit resistors can get used too if wanted.
And again: keep it simple and keep the wires short. Try to
avoid long leeds and wires. There is also need need for the
use of shielded wires - contrariwise they could "kill"
the sound.
If you use a good 12 V / 12,6 V powersupply the Pepper is
very quiet, no massive his and also no hum.
How To Build MK II:
Version 2 of the Pepper Shredder was build on PCB. Unfortunatly
we do not have pictures ready yet so for the moment please
refer the picture of the Vanilla Overdirve in the previouse
chapter.
Parts / Kits:

Alternatives
Besides the official releases of the PepperShredder, there
is also an unofficial version, in which the power supply is
designed for 24 V and a Tone-Stack from a Marshall 18 watt
is used. This illustrated version was tested by us and works
fine, but it is currently not supported - say there is no
kit and further support available.
