I have a Super Duper 2 in 1 by Z Vex... So I am covered as far as a clean boost.. I want to replace my SD-1 Boss Overdrive with something boutiquey and more expensive because its fun... So I think i've settled on the TIM or TIMMY I can't find any info about either online through google etc... what does the tim have that timmy does not? since i already have a beautiful clean boost, do I need a TIM?
