Re: Dynacomp vs Supercomp?
I have found that having the attack control makes a comp a lot more versatile. The old Dynacomps were pretty much a one-trick pony, in that the preset attack made it pump at higher compression (sensitivity) settings, so most guys set the sensitivity low and cranked the level. In that respect, the Super Comp would be better, if you are limiting yourself to MXR stuff, as it has the attack control.
My two favorite comps are both BBE pedals: The Orange Squash, which is based on the Orange Squeezer, with added true bypass, LED, and attack pot, and the Bench Press, a Ross Comp (which was an "improved" DynaComp) clone also with TB, LED, and attact pot. The Orange Squash sounds great at any compression setting, with no "pumping", the Bench Press is a great Ross comp-sound, with the improvements. For the old DynaComp sound, I use a Whirlwind Red Box, which is a handwired script DC clone with LED and TB, designed by a guy from the original MXR company. No attack pot on that one, so I use it as described previously, sensitivity low and level up.
