The (S)cream

The (S)cream is an advanced diode overdrive that develops the sonic potential of the classic small green box :
Its sound comes from the TS9, but not exclusively centered on midrange: The (S)cream can as well recover the sound of 1975-85, recall the nervous grain of the first Black Face amps, or generate a contemporary overdrive …

The (S)cream basic - Boîtier - 1- les deux versions

The (S)cream —  Basic version and  *** version.

The Tube Screamer® family were a turning point in the late 70s, and remains a reference.
The narrow bandwidth made it possible to overdrive the most shrill amps without breaking one’s ears. Furthermore, especially since pure nickel strings became rare, skinny guitars could get some dense colours again.

However, its limits in treble and bass could be frustrating for some musicians : Lack of clarity with humbucker guitars or closed cabinet amps, lack of bottom for heavy strings users. It is by thinking of these critics, and while respecting the original genius of the TS9, that I upgraded the little green beast.

General features

Operational amplifier with diode negative feedback.
3 tone presets :
— Classic (= TS9)

— Brite (sharper)
— Deep (wider bandwidth)
 Customizable and adjustable diode array.
 Op-amp model to choose when ordering.

The (S)cream is designed to operate with a 7 to 12V supply.
(Internal 9V battery, or external power supply. Coaxial jack of 2.1mm, negative center).
An internal electronic filter eliminates residual noises from the power supply :
Hiss from switching power supplies ; hum from poorly filtered transformer supplies.

A lot of options in each version

3 options are available — just click when ordering…

JRC4558D : the classic, still available. Its limited response ensures a warmer sound.
TLO72 : a general purpose model of the 80s. Discreet, it lets diodes do their job …
NE5532 : modern model of the 80-90s. Clear and nervous, recommended for leds.

Choose the diodes

5 options are available — just click when ordering…

Diodes with germanium : soft and compact compression
• They cause specifically a soft grain and a tight dynamic due to their low saturation level.
Silicon Diodes : classic overdrive for a 70s rock / blues sound.
• They cause specifically the grainy and somewhat dark sound from the years 70-80.
Leds : sharp tone and large headroom, for today’s blues, rock or pop.
• They cause a specifical vigorous and colorful sound, with moderately saturated peaks.
Silicium >< Germanium combination : to mix roughness and tight compression
• Silicon causes roughness and harmonics, with a moderate compression.
• Germanium rounds this texture and tightens more the dynamics …
Leds >< Silicium combination : the best to mix crunch and dynamics
• LEDs preserve a colorful and incisive sound before coming into saturation.
• Silicon diodes compress this clear headroom and bring a more bushy texture.
