Product Description ● This effector is a modified version of the vemuram TSV808, with the internal switch for diode clipping and BASS made easily accessible. It also features an added booster, making it a 2-in-1 effector. ● The upper toggle switch selects the diode clipping: down is symmetrical (2 silicon diodes), up is asymmetrical (3 diodes), and middle is symmetrical (4 diodes). ● The knobs are: top left - Booster VOL, top middle - CLIP switch, top right - BASS, bottom left - VOL, bottom middle - TONE, bottom right - DRIVE. Saturation is stored internally, just like the original. ● The op-amp is socketed, allowing for easy replacement.

It can withstand up to 18V. ● True bypass. ● Features a 5mm high-intensity blue LED. ● The aluminum case size is 92 x 119 x 34 (height) mm. ● EBK is a name used only for auctions.
