This pedal has one of the best overdrive sounds I have heard in a pedal. (I think this and the Sansamp are the best pedal overdrives.) I would get another if it was lost or stolen. This model can usually be found at a cheaper price than the fabled TS-9, but some of them are almost identical to the TS-9 inside.
I think it sounds better with a 9v battery, but beware leaving a battery in it - the battery is above the board and will leak on it if the battery leaks. If you use the adaptor then you won't have to worry.
Where Obtained: second hand from a friend
The TS-10 has level, tone and distortion controls. It can run on 9V battery or AC adaptor.
I have used it with single coil- and humbucking equipped guitars. (Strat, Ibanez Blazer, and Gibson Sonex) I have used it with Fender Champ, Peavey Studio Pro, & a small Behringer bass amp.
It sounds good with tube and solid state amps.
It works well for classic rock and blues, and if you use an EQ to "scoop" the mids, it gets a pretty good Randy Rhoads sound for "Crazy Train"!
Its very quiet for a distortion/overdrive effect.
Its just as easy to use as any other 3 knob pedal.
Even 1st position chords will sound good with it.
Hard to get a bad sound out of it. I put the drive knob at 9 o'clock and the others at 12 for a "Sultans of Swing" sound.
I put the drive at 12, level at 12 and tone about 11 for a bluesy sound.
Seems pretty durable. Most of my problems with it are due to a battery leak in it many years back. Once I cleaned out the gunk, I replaced a capacitor and the battery clip. I also had to replace the red LED indicator. Just recently I had to remove and resolder a wire that had broken, probably due to all the other work I did while repairing the pedal.
