This is the TC Electronic Spark Booster (not the mini).

I've had this for about a year, tbh I cant remember if it was new or second hand, but either way it is good condition as you can see from the pictures, and comes with original box. 

I do not gig or anything so this has not left my house since purchase.

NOTE : I have this item for sale elsewhere as well, so I have the right to remove this listing if it sells before I can remove it.

DETAILS : 

• Up to 26 dB of clean boost
• Level and Gain controls, plus a Clean / Fat / Mid selector
• Two-band active EQ with bass and treble that both cut and boost
• True bypass switching
• Dimensions: 2 x 2.8 x 4.8"
• Runs on a 9V battery or a 9VDC centre-negative power supply (not included)
• Original box included
