Boss Pedals, well you can not really go wrong with a Boss, they are good value, last forever and can take a few knocks.

They will loose you some tone but if you combine them with some other pedals and have "true bypass" somewhere in the chain, then no problem.

Favourites are the "KEELEY DS-1", my old PH1-r and the PN-2 tremolo, grab a cheap SD-1 and have a tweak to make it into a TS-9, its almost the same circuit.
