It is an almost perfect clone of the original TS808:
ITS808 home ggg.com (general guitar gadgets, USA)

The mine has undergone these changes:
- 3 Germanium diodes (both parallelism, plus one in series)
JRC4558D-chip (yes made ​​the difference in the harmonics! Also diodes!)
R6 4k7-1k, 51k 10k R7, C3 473-224-0.22F 0.047F)
True-bypass switch millennium
-Switch on / off for the C3 0.22F which adds bass without too botch attack
Biensr resistors must be used "metal film" more accurate than "carbon film

UTILIZATION

But very simple configuration changes:
1 booster amp on distortion channel: metal and comp
2 booster strat clean blues pure joy
3 booster bass: with capacity C3 removed by the switch
4 Overd typ Clash / punk: knob to drive in the middle
5 fuzz / distortion: knob to drive to the max and the volume pot of the south mids

SOUND QUALITY

I love everything, even the parasites pretty reminiscent amps lamp ...
It's a pedal MUSIC foremost and indispensable support for composing / recording!

OVERALL OPINION

I also constructed the TS9 but she seems too aggressive, with less effect screamer bcp / sustain. The modification of the volume pot of a drive for mega is rotten and breaks the beauty of the pedal sound ... personally I handed the knob 500k!

I also availing oneself of a super ibanez tube clone in Russia to the '90s, it is lower in output but also musical ...
RANDOM HARMONIC!
