Compared to the original and much loved Tim pedal, the V3 is in a shorter box with all the pots on top and all the jacks on back. The 3-way clipping switch has the same top and middle settings but with a new 3rd more "open" asymmetrical setting. A 3-way "Hi-Cut" switch is added which helps it sit better with brighter amps/speakers. It's flat in the middle with -3dB @ 3khz and -3dB @ 1k5hz settings. The FX loop is now tied in with the boost for added flexibility in that mode. Internal voltage converter included so the input is +9vdc only. Additionally, the new Tim V3 is true bypass, but controlled by a Soft Switch relay circuit that minimizes the loud pop/click that some pedals have when engaging the switches.
