Ibanez Tube Screamer Ts10 Serial Number
An Ibanez Tube Screamer is an overdrive/distortion pedal that is mild compared to many, but allows the true sound of the guitar and player's technique to come through. The following list are some of the serial numbers and features of TS-808 pedals I have had in the shop or friends' pedals. (R) means the.
The Tube Screamer TS808 by Ibanez is the most famous overdrive guitar pedal. It is suitable for blues and all range of rock music, adding a classic standard tone characterized by the tubelike distortion, good sustain, and smooth overdrive. The frequency response is tailored to emphasize the mid frequencies, creating a hump that helps to keep the guitar sound over the general mix of the band.In terms of electronic design, the hit of the pedal remains on how the signal is filtered and distorted over the stages. The clever schematic is easy to understand and prone to modifications. The circuit was designed in 1979-1980 by S. Tamura, a Japanese Engineer working for Nisshin Onpa/Maxon, an Original Equipment Manufacturer for Ibanez.Due to the pedal success, several versions and reissues were released over the years with small circuit variations.
This article is focused on the first design, which is considered the most attractive: the Ibanez Tube Screamer TS808. Table of Contents:1. Tube Screamer Schematic.The Tube Screamer circuit can be broken down into some simpler blocks: JFET Bypass Switching, Power Supply, Input Buffer, Clipper Amplifier, Tone/Volume Control and Output Buffer.The functionality is simple: The input buffer isolates the pedal from the guitar, keeping the signal fidelity.
Then, the Clipping Amp stage incorporates the distortion to the signal and the Tone/Volume block will add the tonal bass/treble adjustment. Finally, the Output Buffer will prepare the signal to be injected in other pedal or amplifier. The JFET Bypass Switch task is to activate/deactivate the effect and the Power Supply stage provides energy to all the circuit.The pedal has three knobs: Distortion, Tone and a Level.
The Distortion knob controls the level of overdrive, the Tone setting adjusts the amount of treble and the Level knob controls the output volume of the pedal. 1.1 JFET Bypass Switching.The original TS808 Tube Screamer is not True Bypass, so it needs a JFET Switch Circuit in order to activate/deactivate the effect using a simple push button. It can turn the effect on, routing the signal through the circuit core or turn it off, bypassing the pedal and keeping the guitar signal unmodified.The JFET Bypass is formed by two switches and a toggle block to manage these switches:. To activate the effect: Switch A (Q 2) is on and Switch B (Q 4) is off. The signal will pass through all the effect stages. To bypass the effect: Switch A (Q 2) is off and Switch B (Q 4) is on.
The signal will skip the core of the effect but it will still pass through the input and the output buffer.In both states, the signal always passes through the input and output buffer, so it will work as a buffer even whether the effect is bypassed. Buffering the guitar signal avoids tone sucking, this is the reason why some players place the Tube Screamer early in the pedal chain before other pedals without input buffer as the Wah Wah, and therefore keeping sound fidelity.1.1.1 JFET Switch Operation.The switches are implemented with an N-channel JFETs working in saturation/off mode.
The essential part of their operation is to control the biasing of the diodes D 3 and D 4:. If the diode D 3 or D 4 is reverse biased, (gate control voltage is at least V F higher than most positive input signal amplitude) the JFET switch is on and the signal passes through. If the diode D 3 or D 4 is forward biased, (gate control voltage is at least V F more negative than the pinch-off voltage of the FET) the switch is off and the FET presents a high impedance.Note that V F is the forward voltage of the diode.In practice:. JFET is off when V G.
Examples of Ibanez serial numbers on back of headstockIbanez serial numbers are unique identifiers placed on instruments sold under the brand. Ibanez guitars have used serial numbers since the mid 1970s. Some sources say the practice started in September 1975, but serial numbers indicating production as early as October 1974 have been spotted.The serial numbers are generally a character string containing letters and numbers, although some are purely numeric. Serial numbers can be useful in determining the age of a guitar as well as in which country and by which builder it was produced.Unfortunately, there is no single unified format used for Ibanez serial numbers. Guitar production is outsourced to several companies and facilities through the world and the numbering schemes are different in each region and/or factory. The information on this page is culled from several sources both on-line and off-line and represents a distillation of the available information.

What is known is that this rubric is used by Ibanez to set the production date for warranty claims.Note: as of November 2004, the serial number represents not necessarily the year the instrument was produced but rather the model year to which the instrument belongs. It has long been Ibanez's practice to begin production for the subsequent model year in November (or even late October), but the serial numbering change that was implemented in November 2004 acknowledged and formalized this practice.1997–October 2004, FujiGen, 'F' + 7 digits Eight charactersFYY#####single letter ( F)2-digit number5-digit numberExample: (March 1999).
