Formula B That Screamer *Authorized Dealer* FREE Shipping!

"That Screamer 4558" packs into a single pedal three expensive and hard-to-find vintage versions of the world's most famous green overdrive

We have thoroughly examined the original circuitry of our three Original pedals:

TS808 from 1981 The TS9 from 1982 and the TS10 from 1986

from these we have faithfully reproduced the circuitry and capturing every nuance.

The result of this meticulous work has been incorporated into the THAT SCREAMER overdrive professional 4558.

All components have been selected. Inside there are tantalum capacitors for the tone part and we used the bipolar electrolytic capacitors in the buffer part.

The drive circuit consists of the original opamp JRC4558D (Japan Radio Company)

and clipping entrusted to the very rare MA150 diode made in Japan.

In addition to respecting the components, we have improved the dynamics and increased the volume over 5dB

In addition, the pedal is truebypass.

Controls:

DRIVE - Controls the amount of overdrive. Rotated clockwise is more, clockwise decreases. 
TONE - Controls the tone of the pedal. Turned clockwise is brighter, by turning counterclockwise it will be darker.
LEVEL - Controls the output volume. Turning counterclockwise results in less volume, 
in reverse turning the knob clockwise increases the volume.the core can be reached by unscrewing the four screws located on the back. Inside, you'll discover switches that allow you to tailor your sound to your preference.
