I'm pretty happy with this thing.
$45 - 55 and comes with a total of 3 different chips you can swap out. I've never had a TS, so I don't know how it compares, but it sounds pretty good I think.

Mine came with the 3 chips for $45
he Classic Series of pedals are based on the very successful ToneFancier Series. They can be powered by either a 9V battery or by an AC adaptor (sold separately, or you can use any power supply that's compatible with BOSS PSA pedals). Each pedal is made using German made WIMA capacitors which ensures a fast and very low loss signal transfer (not often seen in general effects pedals). Biyang also use only metal, dust proof sealed pots for long life. All pedals feature a True Bypass design making sure there is no loss of tone when the effect is off. Biyang are so confident in the quality of their pedals they offer a free 5 year warranty.
In the 70's Maxon used the JRC4558 chipset and successfully created a much sought after overdrive pedal. Soon, Ibanez, Boss and other pedal makers started to use the JRC4558 to make it so famous. The pedal also features a 3 way toggle switch giving you different diode clipping options. The biggest breakthrough of the OD-8 is the ability to let the user change the chipset to create different tones, without the need for soldering or professional skills. The OD-12 comes with the JRC4558 chip fitted, other chips are sold separately.
