The TS9DX Turbo Tube Screamer was created in 1998 by John Lomas at Hoshino USA to meet Ibanez (Hoshino's) marketing request for a tube screamer with different modes for output and distortion. It has an additional knob along with the old Drive, Tone, and Level knobs. The new knob is a 4 position MODE switch. The TS9DX has the EXACT same circuit as the original TS-9, but the mode switch changes some of the parameters of certain components of the original circuit.
The changes in the circuit for the 4 modes are :
- Clipping diodes : there are several sets of diodes on new boards mounted on the control knobs, that are switched by the MODE knob.
- Tone Capacitor : There are several capacitors on these new mini boards which are also switched by the MODE knob.
