The Ibanez TS5 Tube Screamer is enclosed in a Soundtank enclosure, featuring the same circuitry as the Ts9 Tube Screamer. It offers Drive, Tone, and Volume knobs.
From Analogman:
The TS-5 is the only tube screamer made before 2003 that was not manufactured for Ibanez by Maxon (Nisshin Onpa). They are pretty cheezy but sound quite decent. Several people have asked about modifying the TS-5 Sound Tank into a TS-808, so I got one to experiment on. I am now satisfied with the modified sound so I will offer this modification for those who already have a TS-5 or are on a budget (Like I was when I had a ".edu" in my EMAIL address!). But for the ultimate in tone, the TS-9 will be the best pedal to modify, as all of its other components and the circuit board are just like an 808.
