The Ibanez Tube screamer pedal serial no. 166177,
as made famous by Stevie Ray Vaughan and numerous recording artists.
Was produced (officially) between 1982-1985 however,
there are some very rare 1981 models.
I used to own this very pedal between 1984-1993 when I
sold it to our accountant!
It has been serviced with components from ANOLOG MAN
and has a plug in socket for the chip, meaning it can be converted to TS 808 spec. by just exchanging the component.
This interesting little pedal -aimed at the metal market- was only in production for a year. But in the states, they are gaining popularity because when modded (analog man or pedal doc. ect.) they sound like high gain valve amplifiers.
Bass chorus CEB-3
HM-100 Heavy Metal.
Made by the German Nobels company, a good solid road worthy casing (cheaper than a boss!)
It does what it says on the tin.
7 band graphic on a budget.
