Hehee! Couldn't help myself. It is in reality a TS9 :) If you want it 1:1, then use TA75558 and 2SC1815 transistors (mind the pinout!). You could of course build it with JRC4558D and check the output resistors to make it 808.. I still thought we needed at least one more Soundtank to our library.
The same basic circuitry as the famed TS9 Tube Screamer in a more economical format (the TS9 has a more expensive housing and its handwiring makes it more labor intensive to build than the TS5). Most people can't hear the difference between the our affordable Soundtank Tubescreamer and the more expensive originals. Are you one of the few who can?-why not find out for yourself.
