About This Listing
The TS9 reissue features the same careful hand wiring and analog circuitry as the original classic. Like almost all of the original TS9s, the reissue features the TA75558 IC chip. The TS9DX Turbo Tube Screamer adds three new settings for increased low end crunch: +, Hot,  

Modest Mike's Mean Ass Mod ($59.99)

We start by replacing the op amp with a JRC4558D (or RC4558P if you prefer). Several capacitors are replaced with better quality metal film caps to enhance tone quality.  Key resistors are replaced to match your pedal to original 808 specs, we use metal film resistors to help eliminate background noise. The bass response is improved,  and the pedal has a nice middle now that keeps your guitar sounding good when everyone turns up the volume.  

The "Plus" part of this mod? Additional capacitor and resistor values are changed to put a little more hair on it's chest. You get about twice the normal gain, and also the ability to clean up the sound when you roll back the volume. We top it off with a nice water clear LED. The LED is clear when the pedal is off, and a nice bright blue when the pedal is on. For tube screamer lovers, it doesn't get better than this!  Your tube screamer will sound better from it's head to it's ...fets!

Two added switches. One switch is for an optional bass boost .The other switch is the mean ass switch, but you don't need that switch...unless you want to rock! This switch adds two extra diodes in series with the stock diodes. This gives your TS-9 more gain, pushing it into asymmetrical clipping.  These two switches can give you a variety of sounds...all good! This mod is great for the TS-9DX, TS-7, and also that TS-808 Pro Reissue or TS808HW you bought...you know, the one that was a little milder than you expected. The TX9DX already has 3 boost settings, so only one one switch is needed.
